Dont worry. The at-risk group includes people with 1- low levels of potassium 2- low magnesium, 3- a slower-than-normal heart rate, 4- or people who take certain drugs used to treat abnormal heart rhythms, or arrhythmias. Zpack has been around for more than 20 years. Call your md.There is no long term effect from zpack as related to this story. Your doctor has to make sure you are not in the high risk.
