Claricin 500mg Tablet: A Macrolide Antibiotic for Bacterial Infections

What it is

Claricin is a brand of the generic medicine clarithromycin, which belongs to a class of drugs called macrolide antibiotics. Macrolide antibiotics work by stopping the growth of bacteria that cause infections.

What it's used for

Claricin is used for mild to moderate infections caused by certain bacteria. These include flare-ups of chronic bronchitis, sinusitis, community-acquired pneumonia, throat infections (pharyngitis/tonsillitis), uncomplicated skin infections, and middle ear infections in children. It is also used to treat and prevent disseminated mycobacterial infections, and to help eliminate H. pylori bacteria in adults with duodenal ulcers.

How it's taken

Claricin tablets are typically taken by mouth every 12 hours, with or without food. The dose and duration depend on the type and severity of infection, and must be determined by a doctor or pharmacist. For most infections in adults, the usual dose is 250 mg to 500 mg twice daily for 7 to 14 days. For H. pylori treatment, it is often taken every 8 or 12 hours for 10 to 14 days along with other medicines. In children, the dose is based on weight.

Important cautions

Do not take Claricin if you are allergic to clarithromycin or any macrolide antibiotic. It is also not safe to take with certain medicines: cisapride, pimozide, colchicine (if you have kidney or liver problems), lomitapide, lovastatin, simvastatin, ergot alkaloids, or lurasidone. If you have had jaundice or liver problems while taking clarithromycin before, do not use it. Tell your doctor if you have a heart condition (such as a long QT interval), slow heart rate, or low potassium/magnesium levels. Stop taking Claricin and see a doctor if you notice signs of an allergic reaction, yellowing of the skin or eyes, or severe loose stools.
