Availability Issues and Supply Updates
Since launch, both Wegovy and Mounjaro have experienced intermittent supply challenges in the UK, especially in higher doses. This is partly due to demand outstripping supply, and partly due to the logistics of introducing new medicines into the private pharmacy system.
- Wegovy: supply has stabilised somewhat, though not every dosage is always available. Recent price rises have seen users flood to Wegovy from Mounjaro, which may have knock on effects until things stabilise.
- Mounjaro: supply has stabilised somewhat since the August 25 announcement of price rises, though not every dosage is always available. Higher doses in particular can sell out with some suppliers.
