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.

Minipress falls into category C. There are no good studies in pregnant women. Minipress should be used during pregnancy only if the possible benefit outweighs the possible risk to the unborn baby.

Tell your doctor if you are breastfeeding or plan to breastfeed.

Minipress has been detected in human breast milk. Because of the possibility for adverse reactions in nursing infants from Minipress, a choice should be made whether to stop nursing or to stop use of Minipress. Determining the importance of the drug to the mother should be considered.
