Diphenhydramine Overview

Diphenhydramine (/dafnhadrmin/; abbreviated DPH, sometimes DHM) is a first-generation antihistamine possessing anticholinergic, antitussive, antiemetic, and sedative properties that is mainly used to treat allergies.

Blue Gel Oval Pill A99
little gel blue pill, hard liquid, but still a gel pill, what is it? with A99 on one side. ## This is an over the counter sleep-aid that contains 50mgs of Diphenhydramine. Common side effects may include: nausea, drowsiness, dry mouth and dizziness. Learn more: Are there any questions or comments? ## WHAT HAPPENS WHEN THIS DRUG IS MIXED WITH ALCOHOL? Any other dangerous side effects? Thanks ## @Very concerned You die. ## I take this with Alcohol once or twice a week. You don't die. Diphenhydramine is Benadryl. It is used as a sleep aid as well, and Alcohol will amplify the effects of it. While taking the recommended dose (25-50mg), you'll just get buzzed quicker and fall asleep faster. ## It's not good for your liver to drink on them

zzzquil and Type 2 Diabetes
Is this safe for a person with Type 2 Diabetes? I think it is loaded with sugars but cannot find any exact information about this. I think it might be the reason my sugar count has been up for the past month. I have a problem staying asleep and have been using zzzquil for the past month or so and it seems to help, but if it is keeping my sugar count high I'll have to stop taking it. ## Hello, Larry! How are you? One of the inactive ingredients is high fructose corn syrup, which could raise your sugar levels, especially if you're sensitive to it, as some people tend to be. If you need a sleep aid that doesn't contain it, the active ingredient in this is just Diphenhydramine, 50mgs per dose. Diphenhydramine is available by itself in Benadryl and its generics, as well as in pro...

would ya know what kind of pill this is!! i found it out side of the end of my drive way.of my house on the ground.i do not need for my Daughter to get a hold of it.please let me know what the it is.Thanks..... ## Hello, Lynn! How are you? If there are no markings on it, it is most likely an over the counter product. There are some Diphenhydramine capsules that match this description, they are a generic or store brand of Benadryl, which is used to treat allergies. I'm not certain, but I'll do some more looking and post back, when I have more information for you. Does anyone else have any idea of what this contains?

blue pill 44367*
Diphenhydramine HCI 25 mg-Night time sleep-aid ## Hello, Nicolle! How are you? While it is used as a sleep aid, because it causes drowsiness as a side effect, this is actually an antihistamine. This is the same active ingredient that's found in Benadryl and used to treat allergic reactions. Other side effects may also include dizziness and dry mouth. Is there anything else I can help with?

diphenhydramine sleeping tablet
It a small round plain white tablet. I'm would just like to know the mg before taking ## Hello, Crystal! How are you? I can't tell you anything about it without some markings or something to go by, if there aren't any, we can't even be certain of what the tablet contains. That said, Diphenhydramine is actually not a sleep medication, it is an antihistamine that can cause drowsiness as a side effect, that is often augmented when Acetaminophen is added, so it is often used to help induce sleep. Do you know anything else about the tablet you're questioning?
