if prescribedSample pricingYou'll see your exact total before you're charged anything. Nothing is charged for the visit itself.
Adding to your plan doesn't order anything and doesn't charge you — it tells the provider what you're hoping to discuss.
About 5 minutes. A licensed provider reviews your health and prescribes tadalafil only if it's right for you — there is no checkout here, and that's deliberate.
How it works
What it actually does
The same pathway as sildenafil — inhibiting PDE5 so cGMP persists and vessels stay relaxed — but tadalafil clears from the body more slowly. That's what makes a low daily dose possible, and why the as-needed version has a longer window. Arousal is still required either way.
See the full mechanism, step by stepA provider may consider it if
- You'd rather not plan around timing — the daily option removes that
- You want a longer window than sildenafil offers
- Your cardiovascular history has been reviewed and is clear for it
It won't be prescribed if
- Anyone taking nitrates — the same absolute contraindication as sildenafil, and it lasts longer because the drug does
- Recent cardiac events, unstable angina or uncontrolled blood pressure
- Anyone on alpha-blockers or specific antivirals without a full medication review
These are the same checks the visit runs. If one applies, the visit will tell you plainly rather than take your money.
What to expect
Realistically, month by month
Daily dose
Taken at the same time each day. It takes several days to reach a steady level, so the first day is not the verdict.
As-needed dose
A longer window than sildenafil, which is the main reason people prefer it.
Ongoing
Your provider adjusts based on what you report back.
Safety, stated up front
Side effects, before you decide
Headache, indigestion, back or muscle ache, flushing and nasal congestion are the common ones — back ache is more associated with tadalafil than with sildenafil. Seek emergency care for an erection lasting more than four hours, or sudden vision or hearing loss.
- FDA prescribing information: tadalafil
- Nitrate co-administration contraindication per FDA labelling

Questions
Asked honestly, answered honestly
Daily or as-needed?
Daily suits people who don't want to think about timing; as-needed suits less frequent use. Your provider will recommend based on your health and how you'd actually use it.
