Hives.: Books are written discussing the many causes of hives. The most common cause would be a reaction to a new medication or food. It is often very hard to find the precise cause without doing an elimination diet and or stopping the inciting medication. Hives can also be caused by viruses, airborne allergies, cold, heat, friction and internal disease. ...Read more

Are antihistamines ever known to bring out the hives they r being taken to prevent? My hives get bumped up within 90mins of any antihistamine.

No: Depending what antihistamine you are taking, they usually take 30 to 45 minutes to start working, your hives do not worsen from them but if you are taking the medicine when the hives have already started, they are not controlling them very well. See an allergist and they can guide your treatment better. ...Read more

Allergy to antihistamine is possible but not likely. Vague itching soon after a dose is not a good reason to suspect allergy. ...Read more

I went off antihistamines and 2-3 days later had hives & sudden flushing, hot face. Is it typical to have an effect/backlash like this when stopping?

I went off antihistamines and 2-3 days later had hives & sudden flushing, hot face. Is it typical to have an effect/backlash like this when stopping?

Hives off meds: That is not typical. You may have suppressed an underlying condition which developed while you were taking the allergy medicine for a different reason. If you were taking them for hives, then it just means your condition has not resolved yet. It is common to experience some itching after discontinuation of anti-histamines for a few days but your symptoms sound more than just itching. ...Read more

I've been taking antihistamine meds for some time now, because of my chronic idiopathic hives I'm worry about the side effect & getting immune from it?

Chronic Hives: A number of my patients have been taking high-dose antihistamines for weeks, months, and in some cases even years with little to no side effects. Main side effect can be sedation, otherwise well tolerated. Over time your hives might spontaneously improve so if you have been well controlled for a while now, might be worth attempting a trial wean to see if the hives come back. Talk to your doctor. ...Read more

In class, at home, 1-2/day, Hives are oftenly occure on my full body, tell me the best way to resolve this problem, even antihistamines doesn't work.

Larger dose: Try a non-sedating antihistamine up to 4 x daily (yes much larger than what is used for hay fever). If this does not help. You may add a H2 antagonist such as Pepcid (famotidine) or ranitidine twice daily. If this happens only at home or at school, then there is something in that environment causing the hives. Consult an allergist if the above measures didn't help. ...Read more

How can one get rid of hives without antihistamines?

A few choices: Antihistamines are usually the safest choice. Prednisone can effectively treat most cases of hives, though it can have significant side effects if used long term. Immune-suppressing meds like Cyclosporine can help chronic cases, but also have side effects that must be weighed against the benefits. Some cases respond to a medication used to treat allergic asthma. See an allergist for more info. ...Read more

What antihistamine gets rid of hives but doesn't make you tired?

Try selective H1: Of the antihistamines, Benadryl (diphenhydramine) is the most effective, but also causes the most sedation. Some of the more selective h1 agents (eg. Claritin, Allegra or zyrtec can help). Note, zyrtec is probably a little bit more effective, but also has a sedation rate of 12%. ...Read more

Unusual: Some people develop small itchy hives when the body starts to cool off after exposure to a very warm environment, but your condition appears to be the reverse.
Since avoidance of heat is likely impossible in your area, have you tried taking a double-dose of non-sedating antihistamine 1-2 hrs prior to such exposure? ...Read more

When I take oral antihistamines I get hives over my entire body. Is it possible to be allergic to antihistamines? What can be taken instead?

You should consult with someone familiar with these medications and medication reactions in general, such as an allergist. ...Read more

Female, 51. Hives on all parts of body when outside temp goes below 65. Ice exper. Produces welt. Antihistamines make me jitter. I layer. Other options?

Cold urticaria: This is not too uncommon. Avoidance of exposure is the best approach. I don't understand why all antihistamines make your jittery without a decongestant. Suggest you try different types of just antihistamine to see which one works for you. Double the dose if necessary for the one tolerated. See allergist perhaps? No immersion in cold water-it may kill you. ...Read more

I was diagnosed with hives. Disappeared in 4 days with antihistamine use, could this be a sign of HIV infection?

Not specifically: Hives are called urticaria and can come from many, many reasons. Ofter we are unable to identify a cause. If they improve with anti- histamine that is good. The real truth is after you stop using the antihistamine do they recur. If they recurr many times over a period of time they can be classified as "Chronic Urticaria". When we see a patient with urticaria we think of many causes! ...Read more
