What's the likelihood of getting prolonged qt or torsade de pointes from taking biaxin. i don't have any heart problems. ?

Use HealthTap Prime.: It's hard to say what the likelihood is in your case, without knowing your medical history & getting an inventory of medications you are taking or could potentially take. The risk factors are gender (you're female), age (but you're young), & heart disease. If you've ever had QT prolongation before or electrolyte abnormalities, you should avoid Biaxin or at least be monitored by EKG while taking it
