What are the possible side effects of Depo-Provera CI?
Depo-Provera CI can cause serious side effects, including:
- Effect on the bones: See "What is the most important information I should know about Depo-Provera CI?".
Teenage years are the most important years to gain bone strength. The decrease in calcium in your bones is of most concern if you are a teenager or have the following problems:- bone disease
- an eating disorder (anorexia nervosa)
- a strong family history of osteoporosis
- you take a drug that can lower the amount of calcium in your bones (drugs for epilepsy or steroid drugs)
- you drink a lot of alcohol (more than 2 drinks a day)
- you smoke
If you need a birth control method for more than 2 years, your healthcare provider may switch you to another birth control method instead of using Depo-Provera CI. If you continue using Depo-Provera CI, your healthcare provider may ask you to have a bone test, especially if you have other risks for weak bones.
When Depo-Provera CI is stopped, your bones may start to regain calcium. However, in a study of teenage girls who used Depo-Provera CI for more than 2 years, their hip bones did not completely recover by 5 years after they stopped using Depo-Provera CI. Taking calcium and Vitamin D and exercising daily may lessen the loss of calcium from your bones.
- possible increased risk of breast cancer. Women who use Depo-Provera CI may have a slightly increased risk of breast cancer compared to non-users.
- blood clots in your arms, legs, lungs, and eyes
- stroke
- a pregnancy outside of your uterus (ectopic pregnancy). Ectopic pregnancy is a medical emergency that often requires surgery. Ectopic pregnancy can cause internal bleeding, infertility, and even death.
- allergic reactions. Severe allergic reactions have been reported in some women using Depo-Provera CI.
- loss of vision or other eye problems
- migraine headaches
- depression
- convulsions or seizures
- liver problems
Call your healthcare provider right away if you have:
