QUESTION:
Dear Dr. Heller,
Are there any drugs that affect Depo-Provera’s effectiveness?
ANSWER:
Depo-Provera is a long lasting contraceptive injection. It generally lasts 3 months, and prevents the monthly mood swings many women experience. Occasionally women feel ill on the medications. The only drug interaction is with “aminoglutethimide” – which will make the injection less effective.
