What Experts Say

Clarithromycin is a macrolide antibiotic that works by stopping bacteria from producing the proteins they need to grow and multiply. Pakistani treatment guidelines list it as a first line option for community acquired pneumonia and H. pylori eradication therapy, especially in patients allergic to penicillin.

Doctors in Pakistan often pair Megamycin with a proton pump inhibitor and a second antibiotic for stomach ulcer treatment, since resistance patterns here make dual coverage important. Absorption is not affected much by food, so patients can take it with or without meals based on stomach comfort.

Cardiologists caution that clarithromycin can prolong the QT interval on an ECG, an effect that raises the risk of dangerous heart rhythms in people with existing heart disease or those on other QT prolonging drugs. Regular medical supervision is advised for older patients and anyone with a history of arrhythmia before starting this medicine.
