Key Considerations
- GoodRx Care is likely the most affordable overall for a first-time user, as the $18/month flat fee covers everything (consultation, medication, shipping) [1].
- RedBox Rx offers the lowest per-tablet price ($1) if you buy in larger quantities (e.g., 20+ tablets) [4].
- Rex MD has the lowest per-dose price among major recurring-plan services ($1.60) [12].
- All these services require an online consultation with a licensed provider to issue a prescription; sildenafil is not available over-the-counter [4][8].
UK-Based Alternatives (if you're in the UK)
If you're in the UK, Dr Fox offers the cheapest generic sildenafil at 50p/tablet [7], while Numan starts at £1.95/tablet [2].
For the best value in the US, start with GoodRx Care for an all-inclusive low monthly cost, or RedBox Rx if you want the lowest per-tablet price with bulk purchasing.
