Daily or as-needed? The cost half of the question
Which regimen suits you is a clinical question and not one for a price table. Which is cheaper is arithmetic, and the answer is more surprising than it looks: it barely depends on how often you need it.
At the cash-pharmacy floor that crossover is 51 doses a month — more than once a day. At telehealth subscription prices it drops to single digits.

The crossover at every channel#
| Seller | As-needed | Daily | Crossover | What the figures are |
|---|---|---|---|---|
| Ro telehealth | $10.00/dose | $89.00/mo | 8.9 doses/mo | sildenafil 100 mg per dose; Daily Rise monthly rate |
| Rex MD telehealth | $6.00/dose | $60.00/mo | 10.0 doses/mo | sildenafil 50/100 mg per dose; daily tadalafil at $2/dose x 30 |
| Hims telehealth | $5.00/dose | $79.00/mo | 15.8 doses/mo | midpoint of the published ~$4–6 per-dose range; monthly daily rate |
| BlueChew telehealth | $5.00/dose | $100.00/mo | 20.0 doses/mo | top of the published $3.53–5.00 chew range; DailyTAD monthly rate |
| Amazon Pharmacy pharmacy | $0.57/dose | $14.80/mo | 26.0 doses/mo | sildenafil per tablet with Prime; top of the published daily range |
| Cost Plus Drugs pharmacy | $0.22/dose | $11.22/mo | 51.0 doses/mo | sildenafil 100 mg per tablet; daily tadalafil 5 mg x 30 delivered |
Every figure is authored from a published row rather than parsed out of a price label, because several labels carry a range or a strength ladder and picking a number silently would decide the comparison by accident. The basis column says which published figure each one uses.
What the table actually shows#
The crossover is a fact about the seller, not about you. It ranges from 8.9 doses a month to 51, and that spread has nothing to do with anybody's frequency — it is entirely the difference between paying pharmacy prices and paying subscription prices.
Which is to say: the regimen you choose moves your cost by a factor of a few. The channel you choose moves it by a factor of tens. If you are optimising the wrong one, you are optimising the small one.
What this does not tell you#
- These are different medicines, not two settings of one. Daily plans here are tadalafil; as-needed comparisons are mostly sildenafil. They differ in duration and in how they are taken.
- Daily tadalafil has uses beyond this one. It is prescribed for other conditions too, which can make the regimen the right choice for reasons that have nothing to do with cost.
- Frequency is not a purchasing decision. How often a medicine is appropriate for you is a clinical matter, and the arithmetic above should follow that decision rather than lead it.
- Chewables and troches are priced per dose at a premium over the same molecule as a tablet — that is a formulation choice, and the composition tracker covers what is actually in them.
Common questions#
Is daily tadalafil cheaper than as-needed sildenafil?#
It depends almost entirely on where you buy, not how often you use it. At cash-pharmacy prices the crossover is about 51 doses a month — more than once a day — so as-needed is cheaper for essentially everyone. At telehealth subscription prices the crossover falls to roughly 9 to 51 doses a month, which is a frequency real people reach.
How many times a month before a daily plan is worth it?#
Divide the daily plan’s monthly price by the as-needed price per dose at the same seller. That is the number of doses per month at which they cost the same. Below it, as-needed is cheaper; above it, daily is. Comparing a daily plan at one seller against as-needed at a cheaper one is the more useful comparison, and it usually favours the cheap pharmacy.
Pricing arithmetic, not medical advice. Whether a daily or as-needed regimen is appropriate — and which medicine, at what dose — is a clinical decision for a prescriber who knows your history and everything else you take, including interactions with nitrates and some blood-pressure medicines.
