how long does benadryl take to work
Do not take this drug more than your prescribed dosage. A maximum amount of Benadryl intake within 24 hours is only 300 mg and must not exceed beyond that. Donât take Benadryl if you are recently on monoamine oxidase inhibitors (MAOI) for the last 14 days. A severe drug-to-drug interaction may occur, which may cause serious side effects. Do not drive, operate machines, and perform any other activities that need careful attention as soon as you take this drug.
