Anistreplase

Tell your doctor if you are pregnant or plan to become pregnant.

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.

Anistreplase falls into category C:

In animal studies, pregnant animals were given this medication and had some babies born with problems. No well-controlled studies have been done in humans, though. Therefore, this medication may be used if the potential benefits to the mother outweigh the potential risks to the unborn child.

OR

There are no well-controlled studies that have been done in pregnant women. Anistreplase should be used during pregnancy only if the possible benefit outweighs the possible risk to the unborn baby.

OR

No studies have been done in animals, and no well-controlled studies have been done in pregnant women. Anistreplase should be given to a pregnant woman only if clearly needed.
