A member asked:
I just took diphenhydramine 150mg and feel zoned out, can't stand straight, and chewing food feels difficult. how long will this last?
A doctor has provided 1 answer
Overdose: 50 mg is maximum dose, so "fuzziness " is expected. Need to take Benadryl every 6 hours to be effective. So expect 6 to 8 hours for meds to metabolize.
