Switching Medications
Moving between GLP-1 drugs or formats — why it's common, and why the timing belongs to your prescriber.
Switches happen for every reason treatment is individual: side effects that won't settle, a plateau inviting a mechanism change (semaglutide to tirzepatide), format preference (injection to pill or back), insurance shifts, supply gaps. None of it is failure; it's titration at the level of molecule.
The mechanics are where prescribers earn their role: doses don't map one-to-one across drugs, half-lives overlap, and the safe pattern is typically finishing one, starting the other at an appropriate — often not top — dose on a planned date. Transfer-of-care programs (ours included) do this routinely: current dose reviewed, history carried forward, no restart from zero and no improvised gap.
