Disadvantages

This concern may be greatest during the teen years, when young women should be building bone mass.1 Talk to your health professional about whether the benefits of long-term use outweigh your risks and how you can protect your bones with daily calcium and regular weight-bearing exercise, such as walking or running.2

- Causes slight weight gain
- Fertility may not return for 6 to 8 months after stopping the medication
- May decrease levels of HDL ("good") cholesterol
- Provides no protection against sexually transmitted infections (STIs)
- May increase the risk of chlamydia or gonorrhea infection among women who are sexually exposed to these bacteria. (Depo-Provera users who have any risk of exposure to STIs are advised to use condoms.3)
