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.
