Priapism is a prolonged, often painful erection that lasts longer than 4 hours and does not go away after orgasm or without continued sexual stimulation. It is rare but serious.
What Is Priapism?
Defined as an erection lasting more than 4 hours
Not related to ongoing sexual activity
May become painful over time
Can lead to long-term damage to erectile tissue if not treated promptly
Why It Can Happen
ED medications increase blood flow to the penis. In rare cases, this can lead to poor outflow and a trapped erection. Risk is higher with:
Higher doses of medication
Use of other drugs affecting blood flow
Blood disorders (e.g. sickle cell disease)
History of priapism
How to Reduce the Risk
Take only the prescribed dose
Avoid recreational use or combining with other substances
Don’t take another dose before the previous one has worn off
Avoid using medications not prescribed to you
What to Do If It Happens
If your erection lasts longer than 2 hours:
Try walking, climbing stairs, or doing light exercise
Apply a cold compress to the inner thigh or perineum
Take a cold shower
If your erection lasts longer than 4 hours:
Go to the emergency department immediately
Do not delay. Permanent damage can occur without urgent medical treatment
Priapism is a rare but serious side effect of ED medications. Monitor the duration of your erection.
Anything lasting more than 4 hours is a medical emergency and requires immediate treatment to avoid permanent damage.
Always follow your doctor’s dosage instructions and report any unusual responses.
