How do sildenafil and tadalafil work?
Answered in film.

It is the same active ingredient. Generic sildenafil tablets are FDA-approved medications held to the same standards as the brand. The difference is the name on the label and the price.

Most men take it about an hour before sex. It typically works for four to six hours. A heavy, fatty meal can slow it down; an empty-ish stomach keeps it on schedule.

No. It amplifies your body’s own response to arousal by improving blood flow. Without arousal, nothing happens - which is exactly how it should work.

The most reported are headache, flushing, stuffy nose, and upset stomach - usually mild and short-lived. Rare but serious effects exist; sudden vision or hearing changes, or an erection lasting over four hours, need immediate care.

Because it can keep working for up to 36 hours. You take it, and the pressure of timing disappears - Friday night doesn’t have to be scheduled around a pill.

A low dose taken every day, so the medication is simply always on board. Often chosen by men who want spontaneity without planning anything.

You don’t have to - your clinician does, with you. Broadly: sildenafil for planned occasions, tadalafil for a longer window or daily readiness. Meals matter less with tadalafil.

A drink or two is generally tolerated. Heavy drinking works against you twice - it can drop blood pressure alongside the medication and blunt the response you took it for.

A compounded tablet containing both molecules - sildenafil’s faster onset alongside tadalafil’s longer window. It is prepared by a licensed compounding pharmacy for an individual prescription.

No. Compounded medications are not FDA-approved, and FDA does not review them for safety, effectiveness, or quality before marketing. Your clinician prescribes it only when they judge a combined approach fits your situation.

Anyone taking nitrates (for chest pain) - the combination can drop blood pressure dangerously. Men on certain alpha-blockers or with significant heart disease need an individual decision. This is exactly why a clinician reviews your history first.

The whole visit happens online, and medication ships in plain packaging with nothing on the outside indicating what is in it. Your care stays between you and your clinician.
