How Long Does Clarithromycin Stay In Your System

How long does clarithromycin stay in your system? 500 mg of clarithromycin stays in the body for a period of about 8 to 12 hours. The half-life of clarithromycin (500mg) is 5 to 7 hours. In this duration, if any significant health issue arises, get a medical opinion at the earliest to know if this is unusual.

How long does clarithromycin take to leave your body?

How long does it take for Biaxin to work? In most cases, it should only take a few days for () to reduce the symptoms of your and make you feel better. For some infections, it may take longer for signs and symptoms to go away. For example, clarithromycin can take around 7 days to have a noticeable effect on skin infections such as cellulitis.

Biaxin may also take longer than a few days to resolve symptoms of a stomach infection caused by the bacteria Helicobacter pylori (H. pylori). Even if the drug has eliminated the H. pylori bacteria, symptoms can persist if the infection caused an ulcer to form. In this case, your doctor may prescribe an acid-reducing medication as well.

is typically prescribed as a 7- to 14-day treatment, meaning that even if your symptoms have resolved after a few days, you will still need to continue taking the medication until you’ve completed the entire course of treatment. Stopping the medication early can result in bacteria being left behind, potentially leading to antibiotic resistance and increasing the risk that the infection returns.

The half-life of clarithromycin can range from 3 to 4 hours for a lower dose (250 mg) to 5 to 7 hours for a higher dose (500 mg). This means that 250 mg of clarithromycin will be completely eliminated from the body 16 to 22 hours after taking it, while 500 mg of clarithromycin will be eliminated about a day and a half following the last dose.

Can I stop taking clarithromycin after 5 days?

pronounced as (kla rith’ roe mye sin) Clarithromycin is used to treat certain bacterial infections, such as pneumonia (a lung infection), bronchitis (infection of the tubes leading to the lungs), and infections of the ears, sinuses, skin, and throat.

It also is used to treat and prevent disseminated Mycobacterium avium complex (MAC) infection, It is used in combination with other medications to eliminate H. pylori, a bacterium that causes ulcers. Clarithromycin is in a class of medications called macrolide antibiotics. It works by stopping the growth of bacteria.

Antibiotics such as clarithromycin will not work for colds, flu, or other viral infections. Taking antibiotics when they are not needed increases your risk of getting an infection later that resists antibiotic treatment. Clarithromycin comes as a tablet, an extended-release (long-acting) tablet, and a suspension (liquid) to take by mouth.

The regular tablet and liquid are usually taken with or without food every 8 (three times a day) to 12 hours (twice a day) for 7 to 14 days. The extended-release tablet is usually taken with food every 24 hours (once a day) for 7 to 14 days. Your doctor may tell you to take clarithromycin for a longer time depending on your condition.

Take clarithromycin at around the same time(s) every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take clarithromycin exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.

Shake the suspension well before each use to mix the medication evenly. Swallow the long-acting tablets whole; do not split, chew, or crush them. You should begin to feel better during the first few days of treatment with clarithromycin. If your symptoms do not improve or get worse, call your doctor. Take clarithromycin until you finish the prescription, even if you feel better.

If you stop taking clarithromycin too soon, or skip doses, your infection may not be completely treated and the bacteria may become resistant to antibiotics. Clarithromycin also is used sometimes to treat other types of infections including Lyme disease (an infection that may develop after a person is bitten by a tick), cryptosporidiosis (an infection that causes diarrhea), cat scratch disease (an infection that may develop after a person is bitten or scratched by a cat), Legionnaires’ disease, (type of lung infection), and pertussis (whooping cough; a serious infection that can cause severe coughing).

Is clarithromycin a strong antibiotic?

Clarithromycin is as potent and effective as any other antibiotic when taken in a dosage of 500mg. With its very mild side effects, Clarithromycin is available both as a liquid and a pill to fight an array of bacterial infections.

What not to eat with clarithromycin?

Common side effects – These common side effects of clarithromycin happen in more than 1 in 100 people. There are things you can do to help cope with them: Feeling sick (nausea) Stick to simple meals and do not eat rich or spicy food while you’re taking this medicine.

It might help to take your clarithromycin after you have a meal or snack. Being sick (vomiting) Try taking small, frequent sips of water to avoid dehydration, Signs of dehydration include peeing less than usual or having dark, strong-smelling pee. Do not take any other medicines to treat vomiting without speaking to a pharmacist or doctor.

If you take contraceptive pills and you’re being sick, your contraception may not protect you from pregnancy. Check the pill packet for advice. Diarrhoea Drink lots of fluids, such as water or squash, to avoid dehydration, Signs of dehydration include peeing less than usual or having dark, strong-smelling pee.

• Do not take any other medicines to treat diarrhoea without speaking to a pharmacist or doctor.
• If you take contraceptive pills and you have severe diarrhoea for more than 24 hours, your contraception may not protect you from pregnancy.
• Check the pill packet for advice.
• Bloating and indigestion Try not to eat foods that cause farting (flatulence) like lentils, beans and onions.

Eat smaller meals, eat and drink slowly, and exercise, There are pharmacy medicines that can also help, such as antacids or simeticone, Ask a pharmacist for advice. Headaches Rest and drink plenty of fluids. It’s best not to drink too much alcohol. Ask your pharmacist to recommend a painkiller if you need one.

1. Talk to your doctor if the headaches last longer than a week or are severe.
2. Difficulty sleeping (insomnia) Avoid having a big meal, smoking, and drinking alcohol, tea or coffee in the evening.
3. Try not to watch television or use your mobile phone before going to bed.
4. Instead, try to relax for an hour before bedtime.

If this advice does not help and any of these side effects continue to bother you, keep taking the medicine, but tell your doctor or pharmacist.

Can I take antibiotics for 5 days instead of 7?

Posted on February 24, 2019 by 5908 Do you really need to take those antibiotics for 10-14 days or will five days do? Some providers are changing the way they prescribe antibiotics, based on evidence-based national research, and are recommending a shorter duration of three to seven days in place of the standard duration of seven to 14 days.

A 2016 study published in JAMA Internal Medicine found that a five-day antibiotic therapy was just as effective as a 10-day therapy for treating patients hospitalized with community-acquired pneumonia. The readmission rate was also lower in those who received the shorter duration. “Shorter courses of three to seven days are proven to be just as effective as longer, traditional courses, and can have less harmful side effects,” says Rachel Kenney, Pharm.D., a Henry Ford pharmacist who is co-leading an initiative under the health system’s Antimicrobial Stewardship Program,

The initiative focuses the shorter therapy course for four common bacterial infections:

Bladder infections Cellulitis, a mild skin infection COPD acute exacerbation and community-acquired pneumonia Urinary tract infections

What is the success rate of clarithromycin?

4. Discussion – Previous studies regarding H. pylori infection mainly investigated themes such as the results of antimicrobial susceptibility testing and the comparison between empirical and tailored therapy, These studies concluded that tailored therapy was superior to empirical therapy, which suggests that antimicrobial susceptibility testing before treatment can be important for successful eradication.

However, these studies merely compared the eradication rates between empirical and tailored therapy, without providing significant evidence. To the best of our knowledge, this is the first study to identify the correlation between the susceptibility status for individual antibiotics included in the regimen and the therapeutic outcome for H.

pylori, We determined that the rate of resistance to clarithromycin was 29.6%, which is higher than the results from other studies. One recent Korean nationwide study reported 17.8% as the resistance rate for clarithromycin, This difference might be caused by several factors.

First, the characteristics of the geographic area might influence this result. Most patients in our study lived in a region with high antibiotic prescription rates. Moreover, clarithromycin is a macrolide antibacterial agent that is used for various infections in addition to H. pylori such as respiratory tract and skin infections,

Second, the MIC breakpoint is an important factor for this difference. The MIC breakpoint, which was adopted in previous studies, was an inaccurate criterion, This makes it difficult to compare the resistance rate for clarithromycin or other antibiotics between studies.

Standard triple therapy and concomitant therapy are considered the first-line empirical regimens in Korea in which antibiotics, such as clarithromycin, amoxicillin, and metronidazole, are combined with a PPI. The clarithromycin susceptibility of H. pylori is a significant factor for successful eradication.

Molecular factors such as 23S rRNA mutation are the main mechanisms underlying this resistance, Although the precise mechanism underlying the resistance to other antibiotics is unclear, several gene mutations such as rdxA, frxA, and fdxB (associated with metronidazole resistance) and pbp1A (associated with amoxicillin resistance) have been reported,

We identified the degree of importance for individual antibiotics included in the regimen, which is the strength of this study. Among 77 patients who received standard triple therapy, 62 exhibited successful eradication (eradication rate: 80.5%). We analyzed the eradication rate based on the results of antimicrobial susceptibility testing for clarithromycin and amoxicillin.

We divided the 77 patients into three groups. The first group was susceptible to clarithromycin and amoxicillin, the second group was susceptible to clarithromycin but resistant to amoxicillin, and the third group was resistant to clarithromycin but susceptible to amoxicillin.

The eradication rate was the highest in the first group (eradication rate: 85.9%), and the second group had a higher rate than the third group ( p = 0.013). This suggests that although the two antibiotics are important for eradication, clarithromycin is more effective than amoxicillin. Next, we analyzed the 43 patients who received concomitant therapy, and the eradication rate was 86.4%.

We also divided the 43 patients into three groups. The first group was susceptible to clarithromycin and metronidazole, the second group was susceptible to clarithromycin but resistant to metronidazole, and the third group was resistant to clarithromycin but susceptible to metronidazole.

We found that the first group had the best eradication rate (96.3%) and the third group had poorest (50.0%) ( p = 0.016). This indicates that although the two antibiotics are important for eradication, clarithromycin is more effective than metronidazole. This study has several meaningful messages for H.

pylori eradication. First, it emphasizes the importance of antimicrobial susceptibility testing. Although there are some commercial testing kits for susceptibility testing for clarithromycin, they are not widely used. This study demonstrates the necessity of a molecular testing kit.

1. Moreover, this study also emphasizes the importance of susceptibility testing for not only clarithromycin but also other antibiotics such as amoxicillin and metronidazole.
2. Therefore, a susceptibility testing kit for dual antibiotics is also required for successful eradication.
3. Second, we used a precise cutoff value for the MIC by adopting the EUCAST guidelines.

The observed resistance rates for antibiotics in H. pylori varied from those in previous studies. This variation is associated with several factors, such as the characteristics of the geographic area, method of susceptibility testing, and MIC breakpoint.

1. Among these factors, the unification of the MIC breakpoint is important for comparing the resistance rate across areas and according to the times.
2. There are two international guidelines for antimicrobial susceptibility testing, the EUCAST guidelines and the Clinical and Laboratory Standards Institute (CLSI) guidelines.

Regarding H. pylori, the MIC breakpoint in the EUCAST guidelines was mentioned above. The MIC breakpoint for clarithromycin is ≥1.0 mg/L, but the other four antibiotics evaluated do not have established breakpoints in the CLSI guidelines, However, the cutoff breakpoint values in previous studies were not exact,

• This makes it challenging to evaluate the precise resistance rate.
• Therefore, this study is important, as it provides a standard resistance rate when compared to other studies using the EUCAST guidelines.
• Third, our study indicates that multidrug-resistant (MDR) strains, which have resistance against two or more antibiotics, are important problems in successful eradication.

The MDR rate was approximately 30.4% in our study. Moreover, in standard triple therapy and concomitant therapy, the eradication rate was low for MDR strains. Recently, there were several studies regarding MDR in various infectious diseases including H.

Pylori infection, Based on the results of our study, future studies regarding the mechanisms and new antimicrobial agents for MDR strains of H. pylori will be needed. There were several limitations of our study. First, this was a retrospective study with a small sample size of enrolled patients. Therefore, a prospective and large-scale study is warranted to clarify the significance of our findings.

Second, this study was not a nationwide study, and there was a selection bias for the geographic area of the enrolled patients. However, we divided the enrolled patients into three groups according to the susceptibility status in each regimen, and compared the eradication rates between the three groups.

What bacteria does clarithromycin treat?

Clarithromycin is a macrolide antibiotic whose spectrum of activity includes many gram-positive (Staphylococcus aureus, S. pneumoniae, and S. pyogenes) and gram-negative aerobic bacteria (Haemophilus influenzae, H.

Is clarithromycin giving me anxiety?

Case Report: The potential for antimicrobials to adversely affect mental state This is a case report highlighting the influence that antimicrobials (clarithromycin in particular) can have on one’s mental state. We discuss the case of a middle-aged woman who presented to an acute admissions unit under Irish Mental Health Act for involuntary admission because of concerns expressed by her family and general practitioner regarding a recent change in behaviour and onset of irritable mood.

This lady was diagnosed with an episode of mania that was thought to be precipitated by a combination of psychosocial stressors, recent discontinuation of psychotropic medication and complicated by a recent course of clarithromycin. Antimicrobial-induced mania is a rare but important side effect of some antibiotics.

It should be considered as a risk for patients with and without known mood disorders who develop episodes of mania. Clarithromycin and ciprofloxacin are thought to be the two most frequently associated with development of mania. This case reports aims to highlight the potential for the antibiotic clarithromycin to negatively affect mental state.

At the point of admission it is necessary to enquire about all medications that a patient may be taking, including non-psychotropics. This case report hopes to remind readers of this essential element of history taking. In this case the patient had recently completed a course of clarithromycin therapy although this did not come to light at the point of admission.

It is also important to keep in mind the possibility of an organic or non-psychiatric cause to atypical presentations. It is hoped that this case report highlights one such unusual presentation and that the reader may be reminded of some basic history taking skills and the need to compile a comprehensive list of differential diagnoses.

This is the case of 57-year-old mother of three who presented to an acute psychiatric unit for involuntary admission after the family voicing concerns to general practitioner (GP) regarding sudden onset of erratic behaviour, irritable mood and disinhibition. History revealed that the patient had not been sleeping well in the previous 5 days and reported not feeling able to relax.

She reported having excess energy and decreased concentration. Collateral history revealed that she had appeared confused and preoccupied at times and was hostile and verbally aggressive towards family. Precipitating factors included the sudden death of the patient’s elderly mother 3 weeks previously as well as the patient feeling concerned about her daughter’s ill health.

• Also the patient had been on duloxetine 60 mg once per day but her prescription had run out 4 days prior to admission.
• She had also been prescribed a course of clarithromycin 500 mg three times per day for a lower respiratory tract infection (LRTI) by her general practitioner (GP) which was completed 1 week prior to her presentation to the psychiatry department.

Psychiatric history included having had a short admission (3 days) in 2008 for a mild-moderate depressive episode and also a 6 week admission in 1999 for a steroid-induced psychosis in another mental health service. She had been treated with duloxetine for the previous 24 months by her GP for the treatment of neuropathic pain.

• This woman was living at home with her husband and three adult children.
• She had been in full-time employment until approx 1 week prior to admission.
• She is a non-smoker and non-drinker.
• Regarding medical history, she was being treated for chronic back pain, hypertension and recurrent respiratory tract infections.

Medications prescribed at the time of admission included only duloxetine 60 mg once daily although she was not taking this medication in the preceding 4 days. There was no known family history of mental health problems. Mental state examination at the time of admission revealed a well-groomed woman who appeared agitated and restless.

• Her speech was pressured and there was evidence of flight of ideas.
• She was easily distractible with poor concentration.
• Her mood was notably labile.
• There were no psychotic symptoms elicited and no evidence of perceptual abnormalities.
• She denied suicidal ideation.
• She was offered a combination of stat dose of 5 mg haloperidol and 2 mg lorazepam to help manage her level of distress at the time of admission.

She was started on high-risk observations (15 min checks) and 4 hourly BP, O 2 saturation, HR and temperature checks.

Mini Mental State Examination 30/30 Physical exam Blood tests—full blood count (FBC), urea & electrolytes (U&E), liver function tests (LFTs), thyroid function tests (TFTs) Urine drug screen

All blood test results were within normal limits and physical exam was unremarkable. Urine drug screen was negative. Differential diagnoses at the time of admission included:

F30.1 Mania without psychotic symptoms F30.9 Manic episode, unspecified F31.8 133 Bipolar affective disorder (BPAD), current episode mania without psychotic symptoms F38.0 Other mood disorder—mixed affective episode F39.0 Unspecified mood disorder F06.3 Organic manic disorder

The patient was reviewed by the consultant the following day who found her mood to be elated with possible delusions of reference. She appeared perplexed with circumstantial speech. An admission order under the Mental Health Act 2001 was completed. She was started on olanzapine 5 mg two times a day and clonazepam 0.5 mg three times a day.

• It came to light during consultant review that she had been on antibiotic therapy for a chest infection prior to admission.
• The patient had been treated by her GP with a 7 day course of clarithromycin 500 mg three times a day which finished 1 week prior to psychiatric review.
• The patient’s condition improved very quickly and she was regarded to voluntary status 4 days later and had a period of two nights leave with her family which went well.

Her mental state was fully improved by day 4 with no signs of elation or hypomania. She was then discharged and was followed up in the community. Duloxetine was restarted as it was helpful for her back pain. Olanzapine 5 mg at night was prescribed on discharge.

Clonazepam was reduced to 0.5 mg at night. She was cautioned about the potential adverse effects of clarithromycin on her mood. She was seen in outpatient clinic 2 weeks later and was noted to be very well. She was feeling quite tired so it was decided that olanzapine be reduced to 2.5 mg at night and clonazepam was discontinued.

There were no concerns expressed by family regarding her mental state. She continues to be followed up in clinic on a regular basis. Clarithromycin is an antibiotic commonly used in the treatment of respiratory tract infections, local infections and in the treatment of Helicobacter pylori infection.

1. Common side effects include nausea, vomiting and diarrhoea.
2. More unusual and rare side effects include anxiety, dizziness, disorientation, mania, hallucinations and insomnia.
3. The first description in the published literature of clarithromycin-induced mania was in 1995 where two patients were receiving treatment for Mycobacterium avium infection.

In 1996 a further case was described where a patient developed mania after clarithromycin treatment for a soft tissue infection. Other cases were described from 1998 to 2004 where the antibiotic was prescribed for treatment of sinusitis infection and in another case for the treatment of H pylori infection.

• The mechanism of action for antibiotic-induced mania is thought to possibly involve central nervous system penetration and possible interaction with neurotransmitters although the exact mode of action remains unknown.
• It is recognised that clarithromycin has excellent cerebrospinal spinal fluid penetration.

Treatment of antibiotic-induced mania generally involves discontinuing the offending agent and symptoms improve. However, if symptoms do not resolve quickly or the patient’s level of functioning is impaired then it may be necessary to add a psychotropic medication, for example, antipsychotic with or without benzodiazepine.

We cannot say for certain the exact cause of the short-lived manic episode in our patient but is was important to consider Clarithromycin as a potential causative or contributory agent. It is important to bear in mind that any patient on certain antibiotic medication may be at increased risk of developing mania.

Cases documented in the literature report the occurrence of the symptoms of mania approximately 1 week after initiation of clarithromycin. In our case the symptoms occurred approximately 1 day after discontinuation of the antibiotic. The symptoms tend to resolve very rapidly in 24–36 h although in our case it was closer to 48 h post admission.

• We acknowledge that it is unusual that symptoms worsened rather than improved after discontinuation of the antibiotic.
• However, it is important to keep in mind that there were other factors affecting this patient’s mental state including the stress caused by the death of her mother and the anxiety about her daughter’s ill health.

Another important consideration in this case is the role played by duloxetine. The medication was being taken by the patient for many years for the treatment of neuropathic pain. Two to 3 days after the discontinuation of clarithromycin and while the manic symptoms were beginning this medication was stopped by the patient herself as she failed to have her prescription filled.

What does clarithromycin do to the body?

Descriptions – Clarithromycin is used to treat bacterial infections in many different parts of the body. It is also used in combination with other medicines to treat duodenal ulcers caused by H. pylori. This medicine is also used to prevent and treat Mycobacterium avium complex (MAC) infection.

• Tablet, Extended Release
• Tablet
• Powder for Suspension

Can I take paracetamol with clarithromycin?

Clarithromycin can safely be taken with painkillers such as paracetamol, ibuprofen or co-codamol.

Can clarithromycin stop you sleeping?

Objective – Some central hypersomnolence syndromes are associated with a positive allosteric modulator of GABA-A receptors in cerebrospinal fluid. Negative allosteric modulators of GABA-A receptors, including clarithromycin, have been reported to reduce sleepiness in these patients. We sought to systematically assess the effects of clarithromycin on objective vigilance and subjective sleepiness.

What happens if you skip clarithromycin?

How should I take clarithromycin? – Take clarithromycin exactly as prescribed by your doctor. Follow all directions on your prescription label. Do not take this medicine in larger or smaller amounts or for longer than recommended. Do not use this medicine to treat any condition that has not been checked by your doctor.

Do not share this medicine with another person, even if they have the same symptoms you have. You may take the regular tablets and oral suspension (liquid) with or without food. Clarithromycin extended-release tablets (Biaxin XL) should be taken with food. Do not crush, chew, or break an extended-release tablet,

Swallow it whole. Shake the oral liquid well just before you measure a dose. Measure liquid medicine with the dosing syringe provided, or with a special dose-measuring spoon or medicine cup. If you do not have a dose-measuring device, ask your pharmacist for one.

Clarithromycin is usually given for 7 to 14 days. Use this medicine for the full prescribed length of time, even if your symptoms quickly improve. Skipping doses can increase your risk of infection that is resistant to medication. Clarithromycin will not treat a viral infection such as the flu or a common cold.

Store this medicine in the original container at room temperature, away from moisture, heat, and light. Do not keep the oral liquid in a refrigerator. Throw away any liquid that has not been used within 14 days. If your infection is treated with a combination of drugs, use all medications as directed by your doctor.

Is clarithromycin good for COVID?

Introduction – The COVID-19 pandemic is currently a major concern worldwide. In Japan, a cumulative of 932 361 PCR test-positive cases have been confirmed, and 15 190 deaths were reported by the Ministry of Health, Labour and Welfare in Japan as of 1 August 2021.1 Approximately 5% of the patients with COVID-19 were hospitalised, 1.6% had severe symptoms requiring intensive care and 1.0% died in Japan.2 Recently, dexamethasone and remdesivir have been used as standard treatments for patients with moderate-to-severe COVID-19 who require respiratory support, 3–5 and the monoclonal antibody therapy, such as casirivimab/imdevimab antibody cocktail, have been demonstrated as effective for mild to moderate COVID-19.6–8 However, these treatments require intravenous drip infusion, and no oral medical treatment has been established for mild COVID-19, which accounts for the majority (approximately 80%) of patients with COVID-19.

The mechanism of exacerbation in COVID-19 has been reported to correlate with dysregulation of the immune response, resulting in exaggerated inflammation to produce excessive cytokines (the so-called cytokine storm).9 Indeed, infection with the SARS-CoV-2 induces high expression of inflammatory cytokines, such as granulocyte macrophage colony-stimulating factor and interleukin-6 (IL-6), thereby accelerating the inflammation.10 Therefore, suppression of inflammatory cytokines is an important target for preventing the exacerbation of COVID-19.

This is supported by the evidence that tocilizumab, an antihuman IL-6 receptor monoclonal antibody that inhibits IL-6 signalling, and dexamethasone, anti-inflammatory and immunosuppressing steroid, reduced risk of mortality and exacerbation that required ventilation.11–13 Clarithromycin is a macrolide antibiotic that has been widely used as a monotherapy for bacterial respiratory infectious diseases.

Clarithromycin has also been used as a standard combination therapy with beta-lactam antibiotics for severe community-acquired pneumonia, 14 owing to its ability to suppress inflammatory cytokines.15 16 Viral respiratory diseases, such as influenza, are not an exception in the mechanism of exacerbation, and combination therapy with clarithromycin and antiviral agents demonstrated clinical efficacy in influenza A infection.17 18 Considering the use of macrolides for COVID-19, evidence in the efficacy of azithromycin to COVID-19 is controversial; some reported the beneficial effect of azithromycin on COVID-19, 19 20 while others reported no benefit in patients with COVID-19.21–23 Clarithromycin may have several advantages over azithromycin.

First, clarithromycin is well tolerated, with even lower frequency of adverse events (AEs)/side effects compared with azithromycin.24 25 Second, dose of clarithromycin can be adjusted based on patients’ age, weight and symptoms by using a tablet of 200 mg in Japan.

Third, clarithromycin and azithromycin affect differently to suppress immune cells and inflammatory cytokine production, 26 27 and to inhibit NF-κB activation.28 Together with these, clarithromycin is a good candidate for alleviating symptoms and preventing the exacerbation of COVID-19 by suppressing inflammatory cytokines and could be safely used in patients with COVID-19.

This trial is planned to estimate the efficacy of clarithromycin in patients with mild COVID-19 pneumonia who do not require oxygen administration.

What is the half life of clarithromycin 500 mg?

The elimination half-life of clarithromycin was about 3 to 4 hours with 250 mg administered every 12 hours but increased to 5 to 7 hours with 500 mg administered every 8 to 12 hours.

How do you stop the side effects of clarithromycin?
