Prometrium

In rare cases, women taking Prometrium suffer a sudden drop in blood pressure that can cause them to faint.

Possible food and drug interactions when taking Prometrium

Tell the doctor if you're taking the antifungal medication ketoconazole (Nizoral) or a similar drug. It's possible that it may increase Prometrium's effect.

Special information if you are pregnant or breastfeeding

Because the possibility of harm to a developing infant cannot be ruled out, Prometrium should not be taken during pregnancy.

Prometrium appears in breast milk. The drug is recommended for nursing mothers only if it is clearly necessary.
