Clarithromycin is a macrolide antibiotic used to treat various bacterial infections, including respiratory tract infections (like pneumonia and bronchitis), skin infections, ear infections, and sinus infections. It is also a key component in treating H. pylori stomach ulcers.

Clarithromycin works by inhibiting bacterial protein synthesis. It binds to the bacterial ribosome, preventing the bacteria from producing the essential proteins they need to grow and multiply, allowing the body's immune system to eliminate the infection.

An abnormal or metallic taste (dysgeusia) is a very common side effect of Clarithromycin. It occurs because the medication is secreted into the saliva. This sensation is temporary and usually disappears once the course of treatment is completed.

The dosage depends on the severity and type of infection. 250mg is often used for milder infections or for children (under medical guidance), while 500mg is typically prescribed for more severe infections like pneumonia or as part of H. pylori treatment.

No, you must finish the entire prescribed course even if your symptoms improve. Stopping an antibiotic early can lead to antibiotic resistance, where the surviving bacteria become stronger and harder to treat in the future.

Clarithromycin can be taken with or without food. However, taking it with a meal or a glass of milk can help reduce potential stomach upset or nausea, which are common side effects.

Take the missed dose as soon as you remember. If it is almost time for your next dose, skip the missed one and continue your regular schedule. Do not take two doses at once to make up for a missed one.
