I accidently took two 24hr allegra d on may 1 still have some side effects how long will the med will stay in ur system ?
A doctor has provided 1 answer
Probably 24 hrs: This dose is fine since Allegra has a high margin of safety. I do not expect much side effects at all . The biologic effect will last around a day but there may still be traces of the drug present in your body for a couple more days.
