Which regimen to ask for
| On-demand | Daily | |
|---|---|---|
| Dose | 10 mg or 20 mg | 2.5 mg or 5 mg |
| Timing | At least 30 minutes before sex | Same time daily, sex whenever |
| Suits | Sex once a week or less | Sex twice a week or more |
| Also treats BPH | No | Yes |
| Steady state | N/A | About 5 days |
The crossover point is around two to three times a week. Below that, on-demand usually costs less. Above it, daily often wins on both cost and convenience — see daily vs on-demand.
Pricing
Because daily tablets are low strength and on-demand tablets are high strength, the monthly cost of the two regimens lands closer together than people expect.
The side effect to expect
Back and muscle ache is characteristic of tadalafil, reported by roughly 1 in 20 users. It typically appears 12–24 hours after a dose and settles within a day or two. A lower dose usually resolves it; if not, switching molecules does.
