What to do if…
you have a painful erection that has lasted several hours and will not go away

Produced and maintained by PanicStation.org Published: Last reviewed: Editorial policy USA guide

Short answer

Go to an emergency room now. A painful erection that has lasted several hours, and especially 4 hours or longer, needs emergency care; if you cannot get there safely, call 911.

Do not do these things

  • Do not keep waiting once it has lasted several hours.
  • Do not drive yourself if you are in severe pain, feel dizzy or faint, are intoxicated, or would be unsafe to drive.
  • Do not take more erectile dysfunction medicine, supplements, or injection medicine to try to “undo” it.
  • Do not use extreme cold, heat, force, or pressure on the penis.
  • Do not rely on masturbation, sex, exercise, or other home attempts, and do not let any home attempt delay emergency care.
  • Do not let embarrassment delay you. This is a medical emergency, not a moral issue.

What to do now

  1. Go to the nearest emergency room immediately. If you cannot get there safely, call 911 for an ambulance.
  2. At check-in, use direct wording: “I have a painful erection that has lasted several hours and will not go away. It may be priapism.”
  3. If you have sickle cell disease, say that immediately.
  4. Write down or screenshot these details for triage:
    • When the erection started, using your best estimate
    • Whether it is painful and how severe the pain is
    • Any erectile dysfunction pills, penile injections, alcohol, recreational drugs, recent injury, or new medicines, including antidepressants such as trazodone if relevant
    • Any history of sickle cell disease or previous episodes like this
  5. Bring medication bottles, injection supplies, allergy information, ID, and insurance details only if they are easy to grab. Go now even if you do not have them.
  6. If speaking feels difficult, show staff your phone with the sentence in step 2 and ask to speak privately.

What can wait

  • You do not need to diagnose the type of priapism yourself.
  • You do not need to work out what caused it before going.
  • You do not need to decide about follow-up specialists, medication changes, sexual activity, or long-term treatment right now.
  • You do not need to try multiple home remedies first.

Important reassurance

Emergency room teams treat urgent genital problems and are used to handling them privately. Feeling panicked or embarrassed is common, but getting care quickly is the most protective next step.

Scope note

These are first steps only. After emergency treatment, later decisions about medicines, sickle cell care, erectile dysfunction treatment, or prevention may need help from a medical specialist.

Important note

This is general information, not medical advice, a diagnosis, or a substitute for professional care. A painful erection that has lasted several hours, and especially 4 hours or longer, should be treated as an emergency.
