This risk may increase if you use certain drugs (such as diuretics/"water pills") or if you have conditions such as severe sweating, diarrhea, or vomiting. Talk to your doctor about using clarithromycin safely.Older adults may be at greater risk for developing the serious fast/irregular heartbeat, severe dizziness, and fainting while using this drug.This medication should be used only when clearly needed during pregnancy.
