What is Depo-Provera?
Depo-Provera is a synthetic progesterone that is injected directly into a woman’s arm or buttocks. Each shot protects against pregnancy for up to 14 weeks, but the drug must be administered once every 12 weeks for the patient to remain fully protected. Depo-Provera is made by Pfizer & Co., and was approved by the FDA in October 1992.
Depo-Provera and Idiopathic Intracranial Hypertension
In December 2012, a report funded by the Faculty of Sexual and Reproductive Healthcare in the U.K. outlined a case report of a 23-year-old woman who developed idiopathic intracranial hypertension after being treated with Depo-Provera. It was the only medication she had taken, and she had only been injected once, 2 months before being diagnosed with IIH. She quit Depo-Provera and recovered completely within 4 months.

The most commonly reported symptom of idiopathic intracranial hypertension is severe headache, which has been described as being throbbing in nature. Other symptoms of associated with IIH include:
- Blurred vision
- Double vision (diplopia)
- Eye injury (papilledema)
- Buzzing sound in the ears (tinnitus)

Depo-Provera Linked to Increased Risk of HIV: Meta-Analysis
