The birth control shot is a birth control method taken once every three months. It is one of several birth control options and is sometimes referred to as a “depo” shot – short for Depo-Provera – the brand name of the medicine in the shot. The birth control shot contains progestin, a hormone that prevents ovaries from releasing eggs. It also thickens cervical mucus, which helps block sperm from getting to the egg in the first place. The shot may be administered by Dr. Hill or Nurse Practitioner Cynthia Daniels at the Associates in Women's Health office in Youngstown, Ohio.
