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. It is also used in the management of drug-induced parkinsonism and other extrapyramidal symptoms. The drug has a strong hypnotic effect and is FDA-approved as a non-prescription sleep aid, especially in the form of diphenhydramine citrate. It is produced and marketed under the tr...

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?

spider bite
I have what I believe is a spider bite on my thigh that is red and swollen. It has a hard mass just under the skin and hurts to have anything touch it. The bite is two small puncture holes but the swelling and dark redness much larger , the whole inside of my thigh. My neighbor gave me these pink pills with 44-239 to take for this, what do you think about that? ## Hello, Jeff! How are you? You need to see a doctor for this, it may need to be lanced and drained, from your description, that sounds venomous, rather than just like an allergic reaction. The tablets you've been given are just over the counter 25mg Diphenhydramine, a generic for Benadryl, used to treat allergies and allergic reactions. They will not do much if you've got an abscess forming from venom. Is there anything...

Tablet Name Sleeping Pills
i cant sleep in the nights Please suggest me and give the tablets names ## Have you seen a doctor for this? Insomnia can have natural causes, or it can be caused by other medical conditions and if that is the case, you will need proper treatment for such a condition, in order to rectify the problem. Some medications used to treat it require a doctor's prescription, while some are available over the counter, however, since I don't know what country you are in, I don't know what your exact options are. Many over the counter products use Diphenhydramine as their active ingredient, since it is an antihistamine that causes drowsiness as a side effect. ## i just want to know about the tablets like alprax .. for my knowledge ...and suggest me in every posible way

pink pill with the numbers 44 329
Is this pill good for an allergic reaction that cause you to have hives that itch real bad ## Hello, Lesa! How are you? This tablet contains 25mgs of Diphenhydramine, which is an antihistamine that's used to treat allergic reactions, it's even the first choice used if you have a bad one and go to the ER. Learn more Diphenhydramine details here. However, it can cause some pretty serious drowsiness, so it shouldn't be taken at a time when you need to be alert, such as when you need to drive or operate machinery. You should also only take it, if your doctor says that it is safe for you. Is there anything else I can help with?

pink oval shaped pill with no imprints
more of a capsule shape pink in color no imprint on either side ## Hello, Judy! How are you? Without any imprints, it's difficult to narrow down an identification with any certainty. We can rule it out as being a U.S. manufactured and approved prescription tablet, since they are all required to have imprints to enable their identification. That means that it's most likely an over the counter product and that leaves it wide open to many possibilities. Just as an example, I have some tablets matching this description sitting on my shelf right now, they contain 25mgs of Diphenhydramine, a store brand of Benadryl, which is used to treat allergies. Learn more Benadryl details here. I'll keep looking and post back, when I have information for you. Does anyone else have any idea of...

pink and white capsule e648
pink and white capsule e648 ## what is this pill,and what is it used for. ## This is Diphenhydramine 25mgs, a generic or store brand of Benadryl for allergies. ## correct, the capsule is in fact Diphenhydramine... However this medication in point of fact is also VERY commonly used as a sleep aid which you can find at any corner drug store, as well as in the same strength in Tylenol PM Sominex etc. Benadryl, or Benehist are Antihistemines for allergies.. which do as well make you drowsy... ## the pill is half pink and half white it says e648 on it ## My brother is in the Army and I found them in the pocket of his pants. So i just wanted to known if they can be fatal. They were just in a bag, not even in a box or a bottle. ## What is a shocker. My friends make this hand sign kinda like th...

pink unmarked capsule
I found a baggie of unlabeled hot pink capsules with white powder inside. Does anyone know what this could be? ## Hello, Killakev! How are you? Without any markings, it's difficult to determine what they contain, unless you would pay to have them lab tested somewhere. However, we can rule them out as being a U.S. prescription product, since they are all required to have markings to enable their identification, in case of emergency. And a wild stab at what they are, but I've seen some Diphenhydramine capsules that meet this description, a generic or store brand of Benadryl. Learn more Diphenhydramine details here. Does anyone else have an idea of what these might be?
