Does Wegovy pill cause headaches?

Yes, and it is on the label rather than only in reports: headache appears among the common adverse reactions in Wegovy pill's FDA prescribing information, published 2026-06-30. Listed means it was seen often enough in the trials to be printed, not that it happens to everyone. The same reaction is on the label of Wegovy too, on the same molecule, though not on every label that carries semaglutide. The headache these labels list is usually the ordinary one that follows eating and drinking much less: less fluid, less salt, longer gaps between meals, and often less caffeine than the day before. It is listed on the label, and it is also the symptom most likely to have a cause you can fix in an afternoon. It clusters in the days after each dose increase. Wegovy pill steps up on a published schedule that reaches the maintenance dose at week 13. Most people see a few rough days after each step and a settling in between, not one long stretch. Once you are at 25 mg once daily and no longer stepping up, the trigger stops recurring. What helps first: fluid first, and enough salt with it. Both drop with intake and both cause this. It stops being ordinary at a specific line: a headache that arrives suddenly and severely, or comes with fever, a stiff neck, visual change, weakness or confusion. Also any headache with a blood pressure reading well above your usual.
