Plain-language guide

Tadalafil, explained by our clinical team

What it is

Tadalafil is the long-acting member of the PDE5 family. A single dose works for up to 36 hours, and a low daily dose provides continuous readiness without timing.

Because it also relaxes smooth muscle in the prostate and bladder, it is the one PDE5 inhibitor approved to treat BPH symptoms.

FDA-approved uses

Erectile dysfunction
Signs and symptoms of benign prostatic hyperplasia
ED and BPH together

Our doctors prescribe for approved uses. Any other use is a decision made only by your doctor, for you, after evaluation.

How it is taken

Either 2.5–5 mg once daily at the same time each day, or 10–20 mg as needed before sexual activity, no more than once a day.

What to expect

With daily use, erections become reliably easier within a week; urinary flow symptoms improve over about four weeks. Headache, back or muscle ache, flushing and indigestion are common.

Who should not take it

Anyone taking nitrates or riociguat
Unstable heart disease or recent stroke
Severe liver or kidney disease without dose adjustment

Questions we hear

Daily or as needed?

Daily suits men who want spontaneity or who also have BPH symptoms; as-needed suits occasional use.

Can I drink alcohol?

Moderate amounts are usually fine; heavy drinking raises the chance of dizziness and low blood pressure.

Is it safe with finasteride?

Yes, that combination is common for men with BPH.
