Cautions with other medicines
Other medicines will not usually affect how medroxyprogesterone contraceptive injections work.
But tell your nurse or doctor when you go for the injection if you're taking other medicines. You can also talk to a pharmacist.
Mixing medroxyprogesterone contraceptive injections with herbal remedies and supplements
Do not take St John's wort, a herbal remedy used for depression, with medroxyprogesterone contraceptive injections. It can affect the way medroxyprogesterone works.
There's not enough information to say that other complementary medicines, herbal remedies and supplements are safe to take with medroxyprogesterone contraceptive injections. They're not tested in the same way as pharmacy and prescription medicines. They're generally not tested for the effect they have on other medicines.
