Does anyone have upset stomach from taking this drug? For people using it to sleep-do you have to keep increase the dosage in order for it to be effective?

I have a script for Ambien, it doesn't work for me at all. My Daughter gave me some Trazadone and I take half of one and two Benadryls, and i sleep for 5 1/2 to 6 hours. I have been taking Benadryl for about 7 years, and by (2) its self its good for two to three hrs. sleep. No side effects.

It was like a roller coaster ride with some attributed anxienty

Started having body itch all over my body and was told by a doctor to try benadryl allergy. The relief was almost instant, but got drowsy pretty quickly but would wake up in the morning alert (big plus). Relief lasts for up to 24 hours on just one 25mg tab. Sometimes though, I wouldn't really say whether I'm taking it for the restful sleep or the itching, but I'm please to kill two birds with one stone as I was suffering from insomnia from time to time months before I started taking it. I have been taking it almost daily now for two months and I hope this is fine.

if you are on mood stablizers such as (Zyprexa) and possible taking seudoeffedrine for sinus headache. Be advised : Could cause a dimentia like symptom mixed with sleep disruption.

Took this for a week due to SEVERE allergies (nothing else helped!) And I got fast/irregular heartbeats, trouble breathing. So bad I took myself to the Urgent Care and they scripted me Allegra. 1 day w/ no benadryl so far and no more anxiety/hb issues. Allegra is helping w/ the allergies too! Be CAUTIONED if you take this drug. Benadryl always used to help w/allergies and sleep but now it scares the CRAP out of me. I'm only 31 and otherwise healthy so be warned!

Hives from bedbug bites. Benadryl stops the itch for about 4 hours per 25mg pill. The stuff is magic. Histamine causes capillaries to be porous enough to leak plasma, but not hemoglobin. This is where swelling comes from. A histamine blocker like Benadryl (or any diphenhydramine hydrochloride) blocks the hystamine receptors and prevents the reaction. It doesn't cure the reason for hives, but makes the itch go away real good. Plus drowsy.

Worked really well.

This medication help me get better while i slept although it does make you a little drowsy.

my boyfriend got string today and is not feel to good

benadryl stopped the itching, though after taking it i cannot sleep. took 6 pills at intervals and was awake every hour the whole night
