An Introduction to Your Dosage of Medroxyprogesterone Subcutaneous Injection
As is always the case, do not adjust your dosage unless your healthcare provider specifically tells you to do so.
Medroxyprogesterone Subcutaneous Injection Dosing Guidelines
The standard dose of
medroxyprogesterone subcutaneous injection for preventing pregnancy and for relieving pain caused by endometriosis is 104 mg every 3 months (every 12 to 14 weeks). The first injection should only be given at a time when pregnancy is not a possibility. These times include:
- The first five days of the menstrual period
- The sixth week after birth in women who are breastfeeding.
Medroxyprogesterone subcutaneous injection is most effective if given every 12 to 14 weeks. If more than 14 weeks have passed since the last shot, pregnancy should be ruled out again before another shot is given.
If you are switching from another form of birth control to medroxyprogesterone subcutaneous injection, your healthcare provider will determine when you should receive your first shot to ensure you have continuous birth control coverage. For example, you may receive your first shot:
- Within seven days of taking the last active birth control pill, if switching from combination oral birth control (birth control pills that contain estrogen and progestin)
- Within seven days of removing the birth control patch or ring, if switching from these methods of birth control
