What if an erection lasts more than 4 hours on Levitra?

Four hours is the call. Rare reports exist of erections lasting greater than 4 hours and of priapism (painful erections greater than 6 hours) for this class, including vardenafil. If an erection lasts longer than 4 hours, the patient should seek immediate medical assistance. If priapism is not treated immediately, penile tissue damage and permanent loss of potency may result. The 20 mg ceiling does not change the phone number. The same stop sits at 2.5 mg.

01After an emergency visit, can 20 mg restart at home?

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

Restart is a clinician decision after the cause is clear. This page will not reopen 20 mg by inbox the morning after a 4-hour erection.

Bring the exact time of the swallow, the milligram, and any second PDE5 or alpha-blocker to that visit. The vardenafil 20 mg vault is a label page, not an after-care plan.

02What other sudden stops sit next to this one?

Sudden loss of vision in one or both eyes can be NAION. Stop Levitra and seek care. Sudden decrease or loss of hearing, sometimes with tinnitus and dizziness, is the same stop-and-call instruction.

Those rows are not priapism. They are the other class emergencies that outrank a 20 mg coupon. Chest pain with a nitrate in the kit is the third.

03Is a 3-hour erection a success story?

A prolonged erection is a warning, not a review-site win. The labelled goal is a response with stimulation, not a hours-long rigidity contest.

Do not take a second PDE5 to 'keep it'. Do not add 20 mg on top of leftover tadalafil. The once-daily cap and the class stop both apply.

04Does 2.5 mg skip this warning?

The priapism warning is a class row. It is not waived at 2.5 mg and it is not created by 20 mg. CYP caps and age-65 starts still carry the 4-hour call.

The stamp on the tablet does not change the emergency number. Say vardenafil was taken, and say when.

05Who sits on the caution list?

Use caution in anatomical deformation of the penis (angulation, cavernosal fibrosis, Peyronie's disease) and in conditions that predispose to priapism: sickle cell anemia, multiple myeloma, or leukemia. Those histories belong on the visit that writes any strength.

A prior erection that lasted more than 4 hours is on the patient leaflet's 'tell your doctor' list. Do not hide that night from the next prescriber.

06When does the insert say to get help?

In the event that an erection lasts more than 4 hours, seek immediate medical assistance. Pain is not required for that 4-hour call. The class also names priapism as a painful erection greater than 6 hours.

Waiting until morning because 'it might go down' is how tissue damage starts. The 20 mg tablet is not a reason to wait longer than 4 hours.

Vault consult

Answers follow the U.S. Levitra label.

Orla H. Three hours and still rigid after 20 mg. Wait it out?

Vault reply

The insert's call is an erection lasting more than 4 hours, painful or not. Do not plan to sleep on it.

Jamal E. I have sickle cell. Is 20 mg closed?

Vault reply

Sickle cell anemia is a labelled caution because it predisposes to priapism. That history belongs to the prescriber before any strength. This page will not clear it.

Ruth P. Does 5 mg skip the 4-hour rule?

Vault reply

No. The 4-hour call is a class warning. It sits at 2.5 mg and at 20 mg.

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.
