What if an erection lasts more than 4 hours after Fildena?

Get care. An erection that lasts more than 4 hours after Fildena 100 mg is an emergency if the unit is sildenafil. The US Viagra file tells patients to seek immediate help at that clock. Priapism - a painful erection longer than 6 hours - can damage tissue and potency if it is not treated. Brand ink does not change the phone number. Men with sickle cell disease, multiple myeloma, leukemia, or a bent penis (Peyronie's, angulation, fibrosis) carry extra caution on that file. The flush probe covers common rows. This probe stays on the four-hour clock.

01What if an erection lasts more than 4 hours after Fildena?

Forest-green still life: four-hour red thread, export tablet

Seek immediate medical assistance. Do not wait to see if morning solves it. Tell the team you swallowed sildenafil, and say 100 mg if that was the stamp.

The Fildena 100 mg vault lists this row with sudden vision and hearing loss. All three are same-day problems.

02Who needs the same-day call after a 100 mg strip?

Anyone whose erection has lasted more than four hours, painful or not. Pain makes it easier to name priapism. The four-hour instruction does not wait for pain.

Mateo signed this probe on 2 September 2026. Emergency care is a hospital, not this inbox.

03Does brand ink change the emergency number?

It does not. Fortune art and Pfizer art share the salt. The clock is the salt's clock. A jelly sachet that named sildenafil uses the same four hours.

Do not email a photo to [email protected] while you wait. That inbox is not emergency care.

04What should you do while waiting for care?

Go. Do not swallow a second PDE5 tablet. Do not add a nitrate. Do not try to 'walk it off' past the four-hour mark as a plan.

The stimulation probe is about starting an erection. This page is about one that will not stop.

05Why does the clock start at four hours, not overnight?

The labelled patient instruction is four hours. Priapism as a painful erection is written as longer than six hours. Tissue injury does not wait for a convenient clinic slot.

A 'still going at dawn' story is already late. The file wants the call at four.

06Which men carry extra priapism caution on the file?

Men with anatomical deformation of the penis - angulation, cavernosal fibrosis, or Peyronie's disease. Men with conditions that predispose to priapism: sickle cell anemia, multiple myeloma, or leukemia.

There are no controlled clinical data on safety or efficacy in sickle cell or related anemias. That sentence is a caution, not a DIY experiment with a 100 mg export stamp.

Vault consult

Answers follow the U.S. Viagra (sildenafil) label for the INN; Fildena is an export carton name.

Maja R. Five hours and still hard after Fildena 100. Wait until morning?

Vault reply

No. The labelled clock is four hours. Seek immediate care. Say sildenafil 100 mg to the team.

Quentin S. I have sickle cell. Is Fildena 100 a special problem?

Vault reply

The US file says use caution in men predisposed to priapism, including sickle cell. There are no controlled data in that group. Ask the clinician who already knows your blood before anyone names a PDE5.

Leila H. Painful at six hours. Same phone?

Vault reply

Yes, and you are already past both labelled clocks. Get care now. Untreated priapism can permanently damage potency.

Before you start, stop, or change any medicine, speak with your prescriber or pharmacist - they hold your chart, this vault card does not. Open the vault disclaimer.
