Your healthcare provider will decide if you need heart monitoring (electrocardiogram or ECG), or blood tests during your treatment with Halaven to watch for this problem.

The FDA categorizes medications based on safety for use during pregnancy. Five categories - A, B, C, D, and X, are used to classify the possible risks to an unborn baby when a medication is taken during pregnancy.
Halaven falls into category D. There are no well done studies in pregnant women. In animal studies, pregnant animals were given this medication and had some babies born with problems. This medication is expected to cause fetal harm when administered to a pregnant woman. However, in some serious situations, the benefit of using this medication may be greater than the risk of harm to the baby.
