Thanks for your query.
The correct dose for AVIL
for adult and children of more than 12 years of age is 25 mg tabs thrice (three times) daily.
I think you should complete the dose or may continue until the allergic rashes persists. But if side effect appears in the form of drowsyness, GI symptoms, dry mouth
you may discontinue the tablet otherwise you should complete the course.
