Always inform your doctor about all medications you are taking, including over-the-counter drugs and herbal supplements, before starting Prometrium. Certain combinations can lead to undesirable effects.
Specifically, you should avoid or carefully monitor the following while using Prometrium:
- Drugs that induce liver enzymes (like rifampin, carbamazepine, phenytoin, and St. John’s Wort): These medications can accelerate Prometrium’s metabolism, reducing its effectiveness. Your doctor might need to adjust your Prometrium dosage. Oral anticoagulants (like warfarin): Prometrium can potentially alter the effects of blood thinners. Close monitoring of your INR (international normalized ratio) is crucial to prevent bleeding or clotting complications. Drugs metabolized by the same liver enzymes as Prometrium: This can lead to increased levels of either drug, possibly causing unwanted side effects. Examples include certain anti-depressants and anti-anxiety medications. Your doctor will consider potential interactions carefully before prescribing any concurrent medication. Hormonal medications (including birth control pills): Prometrium is a progesterone medication; combining it with other hormones can disrupt hormonal balance and lead to unexpected results. Discuss all hormonal therapies with your physician.
