Clarithromycin ER is an extended-release macrolide antibiotic used to combat bacterial infections of the skin and respiratory tract. It is also part of combination therapy to eradicate Helicobacter pylori, a bacteria linked to stomach ulcers. The medication works by killing bacteria and stopping their growth. It is crucial to finish the entire prescribed course, even if symptoms improve, to prevent antibiotic resistance. This drug does not treat viral infections like colds or flu. Before starting treatment, inform your doctor of any history of heart conditions (especially long QT syndrome or coronary artery disease), myasthenia gravis, liver or kidney disease, diabetes, or electrolyte imbalances. Clarithromycin ER is not recommended during pregnancy as it may harm the fetus; effective contraception is advised during treatment.
