Patients with respiratory tract/skin and soft tissue infections.
Adults:
The usual dose is 250 mg twice daily although this may be increased to 500mg twice daily in severe infections. The usual duration of treatment is 6 to 14 days.
Children older than 12 years:

Children younger than 12 years:
Use of Klaricid 500mg Tablets are not recommended for children younger than 12 years.

Therefore, children under 12 years of age should use clarithromycin paediatric suspension (granules for oral suspension).
Clarithromycin may be given without regard to meals as food does not affect the extent of bioavailability.

a. Summary of the safety profile The most frequent and common adverse reactions related to clarithromycin therapy for both adult and paediatric populations are abdominal pain, diarrhoea, nausea, vomiting and taste perversion. 8). There was no significant difference in the incidence of these gastrointestinal adverse reactions during clinical trials between the patient population with or without pre- existing mycobacterial infections.
b. Tabulated summary of adverse reactions The following table displays adverse reactions reported in clinical trials and from post-marketing experience with clarithromycin immediate-release tablets, granules for oral suspension, powder for solution for injection, extended-release tablets and modified-release tablets.
The reactions considered at least possibly related to clarithromycin are displayed by system organ class and frequency using the following convention: very common (≥1/10), common (≥ 1/100 to < 1/10), uncommon (≥1/1,000 to < 1/100) and not known (adverse reactions from post-marketing experience; cannot be estimated from the available data).
Within each frequency grouping, adverse reactions are presented in order of decreasing seriousness when the seriousness could be assessed. System Organ Class Very common ≥1/10 Common ≥ 1/100 to < 1/10 Uncommon ≥1/1,000 to < 1/100 Not Known* (cannot be estimated from the available data) Infections and infestations Cellulitis1, candidiasis, gastroenteritis2, infection3, vaginal infection Pseudomembranous colitis, erysipelas, Blood and lymphatic Leukopenia, neutropenia4, Agranulocytosis, thrombocytopenia system thrombocythaemia3, eosinophilia4 Immune system disorders Anaphylactoid reaction1, hypersensitivity Anaphylactic reaction.

Use of any antimicrobial therapy, such as clarithromycin, to treat H. pylori infection may select for drug-resistant organisms. 6). Clarithromycin is principally metabolised by the liver. Therefore, caution should be exercised in administering this antibiotic to patients with impaired hepatic function.
2). Hepatic dysfunction, including increased liver enzymes, and hepatocellular and/or cholestatic hepatitis, with or without jaundice, has been reported with clarithromycin. This hepatic dysfunction may be severe and is usually reversible.
8) have been reported. Some patients may have had pre- existing hepatic disease or may have been taking other hepatotoxic medicinal products. Patients should be advised to stop treatment and contact their doctor if signs and symptoms of hepatic disease develop, such as anorexia, jaundice, dark urine, pruritus, or tender abdomen.
Pseudomembranous colitis has been reported with nearly all antibacterial agents, including macrolides, and may range in severity from mild to life-threatening. Clostridioides difficile- associated diarrhoea (CDAD) has been reported with use of nearly all antibacterial agents including clarithromycin, and may range in severity from mild diarrhoea to fatal colitis.
Treatment with antibacterial agents alters the normal flora of the colon, which may lead to overgrowth of C. difficile. CDAD must be considered in all patients who present with diarrhoea following antibiotic use. Careful medical history is necessary since CDAD has been reported to occur over two months after the administration of antibacterial agents.
Therefore, discontinuation of clarithromycin therapy should be considered regardless of the indication. Microbial testing should be performed and adequate treatment initiated. Drugs inhibiting peristalsis should be avoided. There have been post-marketing reports of colchicine toxicity with concomitant use of clarithromycin and colchicine, especially in the elderly, some of which occurred in patients with renal insufficiency.
1. 5). 5). 5). 5). 5). Concomitant administration with ticagrelor, ivabradine or ranolazine is contraindicated. Clarithromycin should not be used concomitantly with HMG-CoA reductase inhibitors (statins) that are extensively metabolized by CYP3A4, (lovastatin or simvastatin), due to the increased risk of myopathy, including rhabdomyolysis.
5). 5). Clarithromycin should not be given to patients with electrolyte disturbances (hypokalaemia or hypomagnesaemia, due to the risk of prolongation of the QT interval). Clarithromycin should not be used in patients who suffer from severe hepatic failure in combination with renal impairment.

Patient exposure is estimated to be greater than 1 billion patient treatment days for clarithromycin. c. Description of selected adverse reactions Injection site phlebitis, injection site pain, and injection site inflammation are specific to the clarithromycin intravenous formulation.
4). g. somnolence and confusion) with the concomitant use of clarithromycin and triazolam. 5). There have been rare reports of clarithromycin ER tablets in the stool, many of which have occurred in patients with anatomic (including ileostomy or colostomy) or functional gastrointestinal disorders with shortened GI transit times.
In several reports, tablet residues have occurred in the context of diarrhoea. It is recommended that patients who experience tablet residue in the stool and no improvement in their condition should be switched to a different clarithromycin formulation […]
5). 3). 5). 8). 3). 5). Furthermore, clarithromycin should be used with caution in the following: • Patients with coronary artery disease, severe cardiac insufficiency, conduction disturbances or clinically relevant bradycardia; • Patients concomitantly taking other medicinal products associated with QT prolongation other than those which are contraindicated Epidemiological studies investigating the risk of adverse cardiovascular outcomes with macrolides have shown variable results.
Some observational studies have identified a rare short-term risk of arrhythmia, myocardial infarction and cardiovascular mortality associated with macrolides including clarithromycin. Consideration of these findings should be balanced with treatment benefits when prescribing clarithromycin.
Pneumonia:
In view of the emerging resistance of Streptococcus pneumoniae to macrolides, it is important that sensitivity testing be performed when prescribing clarithromycin for community-acquired pneumonia. In hospital-acquired pneumonia, clarithromycin should be used in combination with additional appropriate antibiotics.
Skin and soft tissue infections of mild to moderate severity:
These infections are most often caused by Staphylococcus aureus and Streptococcus pyogenes, both of which may be resistant to macrolides. Therefore, it is important that sensitivity testing be performed. g. allergy), other antibiotics, such as clindamycin, may be the drug of first choice.
Currently, macrolides are only considered to play a role in some skin and soft tissue infections, such as those caused by Corynebacterium minutissimum, acne vulgaris, and erysipelas and in situations where penicillin treatment cannot be used.
g. Acute generalised exanthematous pustulosis (AGEP), Stevens-Johnson Syndrome, toxic epidermal necrolysis and drug rash with eosinophilia and systemic symptoms (DRESS)), clarithromycin therapy should be discontinued immediately and appropriate treatment should be urgently initiated.
Clarithromycin should be used with caution when administered concurrently with medications that induce the cytochrome CYP3A4 enzyme (see section […]
