A: Take it as soon as you remember. If it's almost time for your next dose, skip the missed dose and continue your regular schedule. Do not double the dose to catch up.

A: Improvement in inflammatory acne is often seen within 6-8 weeks, but a full course may last 3 months or more. It must be taken consistently.
