Adverse effects of Erectile Dysfunction medications

Adverse effects of ED medications

Common side effects

Viagra, Levitra and Cialis don't usually cause severe side effects. Some men have reported headache, flushing, indigestion, and a stuffy or runny nose after taking Viagra, Cialis or Levitra. Men taking Levitra have also reported back pain and muscle aches. In some men, Viagra caused temporary vision changes, such as "blue" vision.

Rare but serious side effects

Vision loss. A few men using Viagra, Levitra and Cialis have had permanent vision loss due to a condition called nonarteritic anterior ischemic optic neuropathy (NAION). However, it's unclear whether the drug - or an underlying condition - caused blindness. If you have a retinal disorder, such as diabetic retinopathy, see your eye doctor before taking any medication for erectile dysfunction.

Sudden hearing loss. Some men have reported hearing loss after taking Viagra, Levitra and Cialis. However, it isn't clear whether the hearing loss was directly caused by taking these medications. If you're taking one of these medications for erectile dysfunction and have sudden loss of hearing, don't take any more of the medication and seek medical help right away.

An erection that doesn't subside on its own. Called priapism, this rare condition can be painful and requires medical treatment to avoid damage to your penis. If you have an erection that lasts more than four hours, see your doctor.
