What Is Depo-Provera?

Depo-Provera DoseDepo-Provera is a birth control shot that contains depot medroxyprogesterone acetate (DMPA), which is a synthetic version of the female sex hormone progestin. Depo-Provera is given as an injection once every three months, and works by suppressing ovulation, preventing the ovaries from releasing an egg for fertilization, and by thickening the cervical mucus to keep sperm from reaching the egg. Many women chose this form of birth control as it is convenient and does not require taking a pill every day or refilling a prescription every month.

This drug was approved for use as a contraceptive by the U.S. Food and Drug Administration (FDA) in 1992. Depo-Provera is currently manufactured by Pfizer, and used by millions of women world-wide. The shot must be injected once every 12 weeks in order for the woman to remain fully protected against pregnancy. Once the hormone has been administered it has a contraceptive efficacy rate of over 99%.

Why is Depo-Provera Dangerous?

Woman having a Migraine from Depo-ProveraUnlike oral contraceptives, that release a small amount of progestin into a woman’s body daily, Depo-Provera delivers a one-time, high dose burst of the hormone into the body. While this method has been shown to be effective in preventing pregnancy, the body needs time to adjust to the change in hormones. Side effects can often be severe during the first month of use. Once the hormone has been injected, there is nothing that can be done to stop the hormones effects on the body other than waiting out the side effects and symptoms.

Why Are There Depo-Provera Lawsuits?

Depo-Provera LawsuitsA number of lawsuits have already been brought against Pfizer for complications linked to Depo-Provera birth control, including a $700 million class action lawsuit filed in Canada, alleging bone loss and osteoporosis side effects from the injectable contraceptive. In 2010, Pfizer settled several class action lawsuits involving problems with Depo-Provera, and product liability lawyers across the country are now investigating claims by women who received Depo-Provera injections in the past and have since suffered other serious medical conditions, like pseudotumor cerebri.

Depo-Provera lawsuits brought against Pfizer allege:

  • The drug maker manufactured a defective and unreasonably dangerous drug.
  • The drug maker failed to adequately warn about the potential link between Depo-Provera and PTC side effects.
  • The drug maker marketed Depo-Provera as a safe contraceptive method for long-term use.
  • The drug maker knew about the potential for serious side effects in Depo-Provera users.
  • The drug maker placed company profits over patient safety.

Have There Been Any Medical Studies Completed On Depo-Provera?

Depo-Provera Medical StudiesOne of the first studies linking birth control and PTC was published in 1995, when researchers described 56 cases in women on contraceptives containing levonorgestrel (progestin).

  • December 2012: A report funded by the Faculty of Sexual and Reproductive Healthcare in the UK identified a case report involving a 23-year-old woman who suffered PTC side effects after receiving only one dose of Depo-Provera birth control two months prior to the diagnosis. After discontinuing treatment with Depo-Provera, the woman made a full recovery within four months.
  • April 2012: In a study published in the medical journal Cancer Research, researchers found that young women who were on Depo-Provera for a year or more were twice as likely as their contemporaries to be diagnosed with breast cancer.

What Has The FDA Done?

FDA meeting about Depo-ProveraIn November 2004, the FDA announced that a black box warning would be added to the labeling of Depo-Provera Contraceptive Injection. This is the FDA’s most severe warning level and is designed to draw attention to serious and even life-threatening side effects that a medication may cause. The new Depo-Provera label warns users that prolonged use may result in the loss of bone density, and that the loss may be greater the longer the drug is administered. Other warnings listed include the risk of severe bleeding, fluid retention, pulmonary embolism and cerebrovascular disorders. It is advised that if any of these symptoms occur, the use of Depo-Provera should be stopped immediately.
