Depo-Provera is a hormonal contraceptive administered by intramuscular injection once every eleven to thirteen weeks. Depo-Provera is manufactured by Pfizer, Inc.
Depo-Provera is commonly prescribed as a birth control method. However, Depo-Provera is also used in treating certain types of cancer, including cancer of the endometrium (lining of the uterus).
A recent study shows that using Depo-Provera long-term may result in significant loss of bone mass density (BMD), resulting in osteoporosis. The loss of bone mass density increases the longer Depo-Provera is used.
On November 17, 2004, the FDA issued a "black box" warning regarding the long-term use of Depo-Provera and its strong causal relationship to significant loss of bone mass density, including development of osteoporosis and osteopenia. The warning reads:
"Use of Depo-Provera may cause you to lose calcium stored in your bones. The longer you use Depo-Provera the more calcium you are likely to lose. The calcium may not return completely once you stop using Depo-Provera."
Due to the concerns over bone loss, both the FDA and Pfizer recommend that Depo-Provera usage be limited to two years, unless there is no other viable method of contraception.
All individuals who have used Depo-Provera as a method of birth control may consider requesting a bone scan from your doctor to determine if you are suffering from osteopenia, the precursor to osteoporosis, or osteoporosis.
If you or a loved one have been diagnosed with osteopenia and/or osteoporosis as the result of using Depo-Provera, you may be entitled to compensation. For a free legal consultation , contact us today!
