User Reviews for Diphenhydramine

Benadryl (diphenhydramine): Dampens down allergy symptoms fast when nothing else available outside of a doctor's office or hospital will. Yes, it puts me right to sleep, so it's not my first choice for everyday seasonal allergy control, but this is the one to keep in the first aid kit for unexpected allergen encounters.

Benadryl Allergy (diphenhydramine): Benadryl seems to help but makes me so sleepy it isn't really worth the symptom relief.

Benadryl (diphenhydramine): I absolutely love Benadryl. It's works fast when I need it and relieves the symptoms enough to make me feel comfortable. It does make me sleepy so I take it at night. I do take it during the day occasionally when I know I don't have to drive anywhere.

diphenhydramine: Diphenhydramine is the "nuclear option" for my hay fever. It absolutely stops the allergic reaction. It's also an unstoppable sedative that will put me to sleep for at least 3 hours.

Benadryl (diphenhydramine): I took this medicine for the first time in my life when I was 19 years old. It didn't work, it gave me the worst side effects ever. Upset stomach, bad headache, body cramps, and dizziness.

Benadryl Allergy (diphenhydramine): I have severe seasonal allergies as well as severe allergies to dust and mold. I had gone through the gamut of second generation antihistamines (Claritin, Zyrtec and Allegra) with minimal success in treating my extreme symptoms. I decided to try the first generation antihistamine: Benadryl. Of course, it's been around for a long time, but it's definitely the most effective. The drawback to this older antihistamine is that it causes sleepiness, and it's not slight. Also, the newer antihistamines can be taken once a day, while Benadryl doses last only 4-6 hours. But to this extreme allergy sufferer, it's a small tradeoff, because it certainly treats the symptoms far better.
