The daily-dosing arithmetic
Daily low-dose tadalafil looks more expensive than on-demand because you buy thirty tablets a month instead of four. In practice the gap is much smaller than expected, because the daily tablets are 2.5 mg or 5 mg while on-demand tablets are 10 mg or 20 mg — and generic pricing is largely per tablet rather than per milligram.
| Regimen | Tablets per month | Typical coupon cost |
|---|---|---|
| Daily 5 mg | 30 × 5 mg | $15–$50 |
| On-demand, sex once a week | 4–5 × 10 mg | $10–$25 |
| On-demand, sex three times a week | 12–13 × 10 mg | $20–$45 |
