Rilonacept and Pregnancy
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.
Rilonacept falls into category C. Based on animal data, this medication may cause harm to your unborn baby. No well-controlled studies have been done in humans. Rilonacept should be used during pregnancy only if the possible benefit outweighs the possible risk to the unborn baby.
Rilonacept and Lactation
Tell your doctor if you are breastfeeding or plan to breastfeed.
It is not known if rilonacept 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 rilonacept.
