Does Benadryl (diphenhydramine) help contact dermatitis rash go away or does be Benadryl (diphenhydramine) only help with itching not the swelling?

Contact dermatitis: Benadryl (diphenhydramine) and other antihistamines treat reactions that are cause by histamine release, like hives (urticaria). Contact dermatitis is inflammation driven by cells of the immune system called lymphocytes. Taking Benadryl (diphenhydramine) for contact dermatitis will make you sleepy but doesn't reduce itch or inflammation. Contact dermatitis responds to topical and if severe enough, oral steroids.

Everytime I go to the country, I get rashes and a terrible itch that keeps me awake during the night. Can Benadryl (diphenhydramine) help?

Yes: THERE MAY BE SOMETHING IN THE ENVIRONMENT YOU ARE ALLERGIC TO THERE. Try to weed that out.Benadryl (diphenhydramine) will help but perhaps daily zyrtec or claritin and 'exclusion' of the triggereing factor would be more long term.

Any good over-the-counter medicine for red rashes on the body due to food, besides Benadryl (diphenhydramine) or claritin?

Skin Issues: Why would you think that your rashes are allergic in nature and you need an anti-histamine? Rashes can represent significant illness. I would need more information about the rash you are concerned about, but the best option is to be seen by your physician and to find out what your rash represents.

Depends: This could be a reaction to a soap or laundry detergent. You may want to avoid TIDE and ALL. This could also be a sign of arthritis if you have the rash and joint pain at the same time.. Next time you get this rash you should see your medical provider.

Dry skin?: Dry skin by far is the most common cause for itching without a rash.Try applying moisturizer all over within 3 mins after bathing while avoiding scented or antibacterial soap. If problem continues, see allergist or dermatologist since there are many potential causes for itching.

See doctor: Many things can cause a skin rash but the more common ones are viral infection and drug reaction. Benadryl (diphenhydramine) only benefits hives caused by histamine but not other rashes. If you have no other symptoms, you may wait a week and see if it disappears. If the problem persists beyond that or you start to develop other symptoms, see your doctor.

I have a 13 wk old baby & she has some rashes on her legs & she is starting to scratch herself. Is it okay to put on some Benadryl (diphenhydramine) anti-itch cream?

Rash infant: No I would not use the Benadryl (diphenhydramine) cream as it can be absorbed by the baby 's skin. I would suggest using a fragrant free and perfume free lotion daily for what may be eczema. If no help get her examined.

I used Benadryl (diphenhydramine) and it dried up my rash in two nights. How did it work?

By itself: The rash would have dried up in the same time with or without benadryl (diphenhydramine). The only way Benadryl (diphenhydramine) might have helped would be its effect on itching thus cutting your edge to scratch the rash

Is it okay to use Benadryl (diphenhydramine) on an 8 month old for rash?

Is it okay to use Benadryl (diphenhydramine) on an 8 month old for rash?

Yes, but why rash?: Although not indicated in this age group, I and many pediatrician use Benadryl (diphenhydramine) for younger patients. However, Benadryl (diphenhydramine) is good for allergic causes of rash, but an 8 month old has many, many reasons for rashes, most commonly due to a virus, for which Benadryl (diphenhydramine) would not help. Because a babies immune system is different than an adults, allergic rashes are less common.
