Priapism: Why a Four Hour Erection Means Go to the ER Now
Priapism, a four hour erection, is a painful erection that lasts longer than four hours and does not ease on its own. It is a medical emergency. Go to the nearest emergency room right away, because waiting can cause lasting damage to the penis (NHS, Priapism).

The basics01
What is priapism, and why does a four hour erection matter?
Priapism is an erection that lasts more than four hours without sexual arousal, or that continues long after arousal has ended. It is not a sign of strength. It is a medical problem.
The NHS calls a four hour erection an emergency and says to get hospital care straight away (NHS, Priapism). Blood becomes trapped in the penis and cannot drain. Trapped blood loses oxygen, and tissue that lacks oxygen can be harmed.
What to do02
What should you do if an erection will not go away?
Go to the nearest emergency room, or call 911 if you cannot get there safely. Do this once four hours have passed, and sooner if the pain is severe.
Tell the staff about every pill, gummy, supplement or medicine you took. Bring the bottle if you can.
- Chest pain, fainting or a racing heartbeatStop and call 911. Do not wait to see if it passes.
- An erection lasting more than four hoursGo to an emergency room now. This needs urgent care to protect the penis.
- Dizzy or faint when you stand, especially on blood-pressure or nitrate medicineSit or lie down, stop the gummy and call your doctor before the next one.
- Rash, swelling or hivesStop. Trouble breathing or a swollen face or throat needs 911.
- Yellow skin or eyes, dark urine or belly painStop and call your doctor the same day. Liver problems have been reported with some herbal extracts.
- Cramps or loose stoolsSorbitol and the other ingredients can upset the stomach. Stop if it continues and ask your doctor.
Call 911For chest pain, trouble breathing, a swollen face or throat, or if someone passes out.

Causes03
What can cause a four hour erection?
Several things can, and they are not all related to supplements. Some prescription erection medicines can do it, and so can other drugs, blood disorders and injuries.
MedlinePlus lists an erection over four hours as a reason for urgent care with sildenafil or tadalafil (MedlinePlus, Sildenafil) (MedlinePlus, Tadalafil).
| Possible factor | What the source says | What to do |
|---|---|---|
| Prescription ED medicine | Label warns of erections over four hours (MedlinePlus, Sildenafil) | Emergency care |
| Tribulus terrestris | Rare case reports of priapism (MSKCC, Tribulus terrestris) | Emergency care |

Does Stallion Power cause a four hour erection?
We have no report of it and no trial of the product, so we cannot say. The gummy is a supplement, not a prescription erection medicine.
The label lists tribulus terrestris inside an 82 mg blend. By our arithmetic from the label order, not a lab test, it can weigh 5 mg or less per gummy. Trials of tribulus used 400 to 750 mg a day (Vilar Neto 2025, tribulus review).
Hidden drugs are a separate worry. FDA has repeatedly found undeclared sildenafil or tadalafil in male enhancement products (FDA, Tainted sexual enhancement products) (Tucker 2018, FDA tainted supplements). We have not tested this gummy and no lab report is published. If anything unusual happens, the label says to discontinue use and consult your doctor. See the side effects page and the hidden drug warnings.
Afterward05
What should you do after a long erection is treated?
Tell your regular doctor, and stop any product you suspect until you have talked. Report a reaction to a supplement through FDA's Safety Reporting Portal (FDA, How to Report a Problem with Dietary Supplements).
Keep taking prescribed medicine unless your doctor tells you to change it (FDA, Mixing medications and supplements). Do not stop a heart or blood pressure medicine on your own.
Gummies look like candy, so keep the bottle away from children (CDC MMWR, Kids and melatonin gummies). See the pricing page only after talking with your doctor.

FAQ06
Questions about long erections
How many hours is too long for an erection?
More than four hours is too long. The NHS treats an erection that lasts over four hours as an emergency and advises getting hospital care immediately (NHS, Priapism). Pain with a long erection is another reason to go sooner.
Can a long erection cause permanent damage?
Yes, it can if it is not treated. Trapped blood lacks oxygen, and tissue can be harmed over time (NHS, Priapism).
Should I wait to see if priapism goes away by itself?
No. After four hours, go to an emergency room. Waiting raises the chance of lasting harm (NHS, Priapism).
Is priapism only linked to erection pills?
No. Prescription erection medicines carry the warning, and rare case reports exist for tribulus, but other medicines and conditions can also cause it (MedlinePlus, Sildenafil) (MSKCC, Tribulus terrestris).
