Does dose affect how long Accutane lasts?
For most medications, a higher dose raises peak blood level rather than per-dose duration. Dosing frequency is calibrated to maintain therapeutic blood levels — not extended by taking more at once.
What to do when Accutane wears off early
If Accutane appears to wear off before your next dose, talk to your prescriber. Options include dose adjustment, schedule change, or switching to an extended-release form — never adjust your own schedule.
