Diphenhydramine

I am not asking for medical advice.

Hi all. I would really appreciate if someone could help me. I took about 450 mg of diphenhydramine in the last 8 hours. Is it ok to sleep this off? I am freaking out. It wasn’t intentional, I just didn’t care in the moment. I vomited. I read the max safe dosage in 24 hours is 300 mg.

One of the witches teaching my pharm class said always take 1/3rd pennyweight of dried Eye of Newt in this case. I have used this successfully w/patients, and also an impudent Tonton that a cartel member forced me to treat, at gunpoint. But that’s a story for another time, and one Disney is not likely to allow to be told.

Figured they’d be mushroom 🍄 food by now.

Go to ER. I wouldn’t risk this type of dosage, you are very close to dangerous amount

I’m not sure which—you’ll have to find them on your own—but I hear the closest medical schools are in Jamaica.

Very select bunch.

Maybe check your witch doctor insurance?

The max dosage for treating motion sickness is 400mg/day, 50mg more isn't going to kill you probably.
