Yes, some patients may be able to switch from a Wegovy injection to Foundayo following a prescriber review. The medicines are not directly interchangeable, and the dose offered will depend on your current Wegovy dose, when you last used it, how long you have taken it and whether you have experienced side effects.
Wegovy injection to Foundayo switching guide
| Current Wegovy injection dose | Estimated Foundayo switching dose |
| 0.25 mg once weekly | 0.8 mg once daily |
| 0.5 mg once weekly | 2.5 mg once daily |
| 1 mg once weekly | 5.5 mg once daily |
| 1.7 mg once weekly | 9 mg once daily |
| 2.4 mg once weekly | 9 mg once daily |
| 7.2 mg once weekly | 9 mg once daily |
This table is Lotus's estimated switching guide. There is no clinically proven dose-for-dose conversion between semaglutide injections and Foundayo, and starting Foundayo above its usual 0.8 mg starting dose is an off-label switching approach that has not been formally evaluated in a direct clinical trial.
Your prescriber may recommend a lower dose, particularly if you have had side effects or there has been a break in treatment. Wegovy and Foundayo must not overlap; your prescriber will confirm when to take your final injection and when to begin the tablets.
