Key takeaways

FDA-approved generic tadalafil in both on-demand and daily strengths.
A single on-demand dose covers up to 36 hours — the practical advantage over sildenafil.
Daily dosing removes the tablet-before-sex ritual entirely.
Daily 5 mg is also licensed for benign prostatic hyperplasia.
Nitrate interval is 48 hours, which matters if you have cardiac disease.

Our verdict

The strongest single product across both Hims and Ro, for one reason that has nothing to do with either company: tadalafil's duration genuinely changes how treatment fits into a relationship. Ro delivers it as an FDA-approved generic in both regimens, dispensed in-house. If you are choosing one product to start with from a telehealth service, this is a better default than sildenafil for most men who have sex more than occasionally — provided the 48-hour nitrate interval is not a concern for you.

Why this molecule tends to win

Head-to-head, tadalafil and sildenafil are equally effective — around 60–70% of men respond to either. Where studies ask men who have tried both to state a preference, tadalafil usually wins, and the reason given is almost always the longer window rather than a firmer erection.

Taken on a Friday evening, a single dose covers most of the weekend. That removes the planning, the clock-watching and the ritual — which for men whose ED has an anxiety component is frequently the whole problem.

Daily or on-demand?

	On-demand	Daily
Dose	10 mg or 20 mg	2.5 mg or 5 mg
Best if you have sex	Once a week or less	Twice a week or more
Spontaneity	Good — 36-hour window	Complete
Treats BPH	No	Yes

The crossover is around two to three times a week. Full comparison in daily vs on-demand.

FAQ

Frequently asked questions

Does Ro tadalafil really last 36 hours?

The drug remains at effective levels for up to about 36 hours, so you can have sex at any point in that window. It does not mean a continuous erection, and arousal is still required.

Can I switch between daily and on-demand?

Yes, through the platform. Do not overlap them — allow a couple of days between the last on-demand dose and starting daily.

Why does my back ache the day after?

Tadalafil weakly blocks PDE11 in skeletal muscle. The ache typically appears 12–24 hours later and settles within a day or two.
