## Key points

- 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.

## 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 comparison that matters**
>
> The same active ingredient at a retail pharmacy with a free discount card typically costs $10–$50 for 30 tablets. Whatever you pay above that is the price of the consultation, the delivery and the convenience — which may well be worth it. It should just be a decision you make knowingly.

## 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.
