Priapism is a long-lasting painful erection. It can cause permanent damage to your penis if not treated quickly.
There are things you can try to reduce your erection.
Call 999 or go to A&E if:
- you have an erection that lasts more than 3 to 4 hours
- you have sickle cell disease and a painful erection that lasts for more than 1 hour
An erection that lasts this long needs to be treated in hospital as soon as possible to avoid permanent damage to the penis.
Treatments to help reduce your erection include:
- using a needle to drain blood from your penis, which is done while the area is numbed under local anaesthetic
- tablets or injections directly into your penis
- surgery to drain the blood through a tiny cut, done while you're asleep under general anaesthetic
Priapism often affects people with sickle cell disease.
Other causes include:
- blood-thinning medicines, like warfarin
- some antidepressants
- drugs, like cannabis and cocaine
- some medicines for high blood pressure
- other blood disorders, like thalassaemia and leukaemia
- some treatments for erectile dysfunction
