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.
Alprolix falls into category C. No studies have been done in animals, and there are no well-done studies in pregnant women. Alprolix should be given to a pregnant woman only if clearly needed.
Alprolix and Lactation
Tell your doctor if you are breastfeeding or plan to breastfeed.
It is not known whether Alprolix crosses into human milk. Because many medications can cross into human milk and because of the possibility for serious adverse reactions in nursing infants with use of this medication, a choice should be made whether to stop nursing or stop the use of this medication. Your doctor and you will decide if the benefits outweigh the risk of using Alprolix.
