Depo-Provera
Also called: depot medroxyprogesterone, birth control shot bone loss
What it means
Depo-Provera is a birth control shot containing depot medroxyprogesterone acetate, given every few months to prevent pregnancy. It lowers estrogen levels, and it carries a warning about bone density loss with long-term use.
Lower estrogen from this shot can speed up bone loss, so it matters if you've used it for years or have other bone risk factors.
Depo-Provera is an injectable form of progestin called depot medroxyprogesterone acetate. It's used as birth control and works partly by suppressing ovarian hormone production, which lowers estrogen. Because estrogen helps protect bone, this drop can lead to faster bone mineral density loss, especially with use lasting several years.
This effect is more noticeable in younger women still building peak bone mass, but anyone using it long-term should be aware of it. For most users, bone density loss tends to partially recover after stopping the shot, though this isn't guaranteed and depends on individual factors like age and overall bone health.
If you've used Depo-Provera for a long time, or you're approaching menopause, it's reasonable to talk with your doctor about whether a bone density scan makes sense. Decisions about starting, stopping, or switching birth control methods should always be made with your prescriber, taking your full health picture into account.
This birth control shot lowers estrogen and can speed up bone loss with long-term use.
