Intrauterine Devices (IUD) with progestogen have been marketed as a safe alternative to birth control
pills and other options such as the patch or injections, but Consumer Safety Watch says manufacturers have failed to warn women and their doctors of the link to pseudotumor cerebri.

Birth control allegedly contributes to the likelihood of acquiring the injury also commonly called idiopathic intracranial hypertension. Excess fluid in the brain can contribute to severe headaches, blurry vision or double vision, permanent blindness and other injuries.
