FDA Warns Zithromax Could Cause Heart Problems


The Food and Drug Administration says a commonly used antibiotic could cause heart problems.

The drug Zithromax and it's typically prescribed in what's called a Z-Pak.

The FDA says it can cause abnormal, and possibly fatal heart rhythms in some people.

Researchers say patients who have low blood levels of potassium or magnesium are at a higher risk, and so are people with irregular heartbeats.

The drug's manufacturer, Pfizer, says the majority of people won't have any heart issues from Zithromax.


A South Carolina woman is doing something a lot of women who've had babies couldn't imagine -- she's teaching fitness classes at eight months pregnant.

Jennifer Warren says she's been active throughout her pregnancy, and actually ran a half-marathon at about four months along.

As she gets closer to her due date, though, Jennifer says she's decreasing the intensity of her workouts.

Experts say staying active during pregnancy can help labor and delivery go more smoothly.
