Yes: If the hives are itchy, you may up the dose of Claritin (loratadine) to 4 x daily but this may cause some drowsiness. Allegra is another option. If the problem gets worse, you will need to see your doctor. Consult an allergist to find out whether you are "sensitive" to all NSAIDs or only to Advil.

See allergist and dermatologist: Your symptoms and clinical picture suggests to different diagnosis as -either simple allergic condition, or connective tissue disease, lupus erythrommatosus. You should be further investigated as blood test and may be skin biopsy may give clue to diagnosis. Avoid sun exposure, taking anti allergic medication and steroids may help.

I have been diagnosed with urticaria which randomly appears on my skin as a rash. Is there any way of avoiding this or reducing symptoms?

I have been diagnosed with urticaria which randomly appears on my skin as a rash. Is there any way of avoiding this or reducing symptoms?

Urticaria: Would sse an allergist who may wish to do some tests depending on your history. If a source is discovered it will need to be avoided. Often one is not and the symptoms can be controlled by the use of over the counter medication called antihistamines. Would ask about the non-sedating ones.

Can urticaria kill me? I've had rashes for 6 weeks, am I gonna die?

Can urticaria kill me? I've had rashes for 6 weeks, am I gonna die?

Hives don't kill: Hives are very itchy and appear unsightly, but do not lead to death. They can be a sign of allergy or if going on for over 4 weeks, may be related to an autoimmune urticaria. Either way, there is pretty good treatment options especially with antihistamines. If there is swelling that affects the throat or breathing difficulties, see your allergist right away.

What are some medications to urticaria (skin rashes all over the body)? Does avyl work and when does its effect start to appear?

What are some medications to urticaria (skin rashes all over the body)? Does avyl work and when does its effect start to appear?

Rash or welts?: I don't know if you are referring to rashes (which tend to be raised or scaly lasting > 1day) or hives (which are raised bumps lasting for a few hours at a time). If it is an itchy rash, topical cortisone cream may help. If it is hives, then antihistamines may help. Cortisone takes several hours and antihistamine about an hour to work.

I keep on having red rashes and it spreads in my body whenever I scratch it. Previous doctor told me it's urticaria. What's the best thing should I do?

Dermatographic: This can best be controlled with an antihistamine- if the rash only occurs with scratching. If they are raised without having been scratched, then they are hives which likewise can usually be controlled with antihistamne 2-4 x daily.

How do I differentiate cholinergic urticaria with miliaria rubra? I got rashes all over my body only after a few weeks of excercise.

CU changes rapidly.: Cholinergic urticaria (cu) will change within a few hours, if not, within a day; comes on more rapidly and leaves more rapidly. Cu will blanch. Taking a hot shower can bring cu instant on. Antihistamines done aggressively will help cu but not so much the heat rash of miliaria rubra. Cholinergic urticaria tends to be more uniform in appearance.

Constant flat rashes for weeks, doc dxd urticaria, worse in heated activity. Mind going crazy w/ burningTold try Zyrtec, (cetirizine) is it safe, not big on meds.

Zyrtec (cetirizine) ok: Even though your condition does not qualify as urticaria which consists of raised welts and usually itchy. There is no harm in trying Zyrtec (cetirizine) which is quite safe although it may cause mild drowsiness in about 10% of the people.
