Benadryl Rash Causes and Reviews


A Rash is an area of irritated or swollen skin. Many Rashes are itchy, red, painful, and irritated. Some Rashes can also lead to blisters or patches of raw skin. Rashes are a symptom of many different medical problems. Other causes include irritating substances and allergies. Certain genes can make people more likely to get Rashes.

Contact dermatitis is a common type of Rash. It causes redness, itching, and sometimes small bumps. You get the Rash where you have touched an irritant, such as a chemical, or something you are allergic to, like poison ivy.

Some Rashes develop right away. Others form over several days. Although most Rashes clear up fairly quickly, others are long-lasting and need long-term treatment.

Because Rashes can be caused by many different things, it's important to figure out what kind you have before you treat it. If it is a bad Rash, if it does not go away, or if you have other symptoms, you should see your health care provider. Treatments may include moisturizers, lotions, baths, cortisone creams that relieve swelling, and antihistamines, which relieve itching.


Benadryl Rash Reviews

Sun, 04 Sep 2011

Can I die from taking this many. Is it physicly addicting? Sorry about my spelling.

Mon, 18 Jul 2011

I loved these strips. I have had allergic reactions to my own allergy shots. After waiting at the Dr.'s office for 15 minutes after my allergy shot, I leave to go shopping. Sometimes I can feel a little thickening in my throat, similar to when I've had a really bad reaction and had to go to the ER for help, or went back to the Dr.'s office for a shot of epinepherine. When I feel just a small reaction beginning, I have put one of the Benadryl Quick Dissolve Strips on my tongue. I get a pretty fast result and I can continue shopping rather than worrying about a worse reaction.

Now, when I went to buy more of this product, it isn't available at any local stores, or on line at safe sites. Each store tells me that people are coming in and wanting them and getting upset when they can't find them.

Why were these strips taken off the market?

Sun, 21 Mar 2010
Does taking too much Benadryl cause a person to fall asleep and not wake up?
Wed, 01 Sep 2010
It was given to me in a hospital through emergency room, for nauseau. Nusrse said that they use it for that as well. Is true and can it be usedat home for the same?
Thu, 24 Mar 2011
My son is allergic to children's Benadryl. It causes him to develop eye infections (conjunctivitus).
Sat, 30 Apr 2011
I've noticed that it when I am with my partner it makes me sensitive, but I am not able to be aroused. Is anyone else having the same issue. I've been taking it for alergies since I was a teenager. Its the only thing that has ever worked for me.
