Q: Why do some people experience initial side effects that later disappear?
The risk of side effects, particularly dizziness and orthostatic hypotension (a drop in blood pressure when standing), is highest after the first dose. This is known as the First-Dose Phenomenon.

The official side effect profile lists somnolence (drowsiness) as a Common reaction, meaning it affects 1% to <10% of users. The risk of dizziness is also highest when starting the medicine. Official documentation does not typically include dry mouth among the most frequently reported adverse reactions.
