Depo-Provera is a popular form of injectable birth control known for its convenience and effectiveness in preventing pregnancy in women. It is administered every 3 months and works by stopping ovulation, thickening cervical mucus, and thinning the lining of the uterus. The drug is manufactured by Pfizer and contains a synthetic hormone called medroxyprogesterone acetate.
Recently, Pfizer has faced many class action lawsuits for the administration of Depo-Provera, as many users of the birth control claim that severe side effects of the drug were withheld from the public.
