Yes, you can switch from Wegovy to liraglutide. These two medications work similarly to help you lose weight, so if you have tried Wegovy and found it doesn’t work for you, then liraglutide could be a good alternative. You will need to speak to your doctor first to make sure that there are no health risks, and you would need to stop taking Wegovy for a while before you could start using liraglutide.
