0.1 mg · 0.2 mg
Coverage
Typically dosed twice daily; also helps sleep when dosed at night. Unlike stimulants, coverage doesn’t switch on and off the same day — the effect builds with consistent daily dosing.
Why there are no dose equivalents
Kapvay works through a different mechanism than stimulants, so no conversion ratio exists between it and Adderall, Vyvanse, or Ritalin. Prescribers start at a standard dose and titrate by response — independent of any stimulant dose you were taking. The converter will tell you the same thing.
