Hello Doc. I was wondering if long term use of benadryl could cause hair loss or hair thinning. I usually take two 25 mg tablets before i go to bed. Sometimes I take three. Also, could taking a large dosage of benadryl have any adverse effects on hair? I was wondering this because i accidentally took two doses(total of 4 25mg pills)in the span of an hour. This is a really great website. Thanks.
I’ve not heard of any connection between Benadryl (diphenhydramine) and hair loss. Antihistamines like diphenhydramine are not known to cause any kind of hair loss, even at higher dosages. There could always be exceptions, but I doubt you’ll see a problem.

I have the same exact problem and I have been researching all over the internet looking for a reason for my hair loss. It has been two years and i have had every blood test done and there is never anything wrong. I have taken every vitamin and used every shampoo out there with no improvement. I even changed my diet - even though i eat pretty healthy normally. I finally came to the conclusion that it is the benadryl i take at night before bed or it’s the ibuprofen i take occasionally for my headaches?? I am in desperate need for help and my doctor says there is nothing wrong with me??
I’ve had the same problem for years. I have basically lost 1/3 of my hair and cannot find a reason why. The only thing I take, and have for years, is over the counter Tylenol Simply Sleep which contains Diphenthdramine (Benadryl). I’ve come to the conclusion, this is more than likely my problem. Since I suffer from terrible insomnia, I’m going to try something else before I’m bald!
