What it is

Joclar is a brand of clarithromycin, a macrolide antibiotic that stops the growth of bacteria.

What it's used for

Joclar is used for mild to moderate infections caused by susceptible bacteria, including acute bacterial exacerbation of chronic bronchitis, acute maxillary sinusitis, community-acquired pneumonia, pharyngitis/tonsillitis, uncomplicated skin and skin structure infections, acute otitis media in pediatric patients, and for the treatment and prophylaxis of disseminated mycobacterial infections. It is also used in adults for Helicobacter pylori infection and duodenal ulcer disease (in combination with other medications).

How it's taken

Joclar caplets are taken by mouth. The typical dosing schedule is twice daily, but the exact dose and duration depend on the infection being treated, the patient's age, and kidney function. For H. pylori eradication, dosing may be every 8 or 12 hours for 10 to 14 days. Dosing for children is usually based on weight. Always follow your doctor's prescription.

Common side effects

Based on available data, serious side effects include allergic reactions, heart rhythm changes (QT prolongation), liver toxicity, and severe diarrhea (Clostridium difficile-associated). For a complete list of possible side effects, consult your doctor or pharmacist.

Important cautions

Do not take Joclar if you are allergic to clarithromycin or any macrolide antibiotic, or if you have a history of liver problems after taking clarithromycin. It is also contraindicated with certain other drugs, including cisapride, pimozide, colchicine (if kidney/liver impairment), lomitapide, lovastatin, simvastatin, ergot alkaloids, and lurasidone. Avoid in patients with known QT prolongation or those taking medications that prolong the QT interval. Discontinue use if signs of hepatitis occur.
