Antihistamine For Hives
Zyrtec (cetirizine): Which drug is better fora specific patient cannot be predicted. I generally try zyrtec first because it does cannot claim not sedating. A little sedation helps alleve itching. Allegra, (fexofenadine) claritn, and Clarinex are allowed to claim no sedation. ...Read moreSee 1 more doctor answer
Post-nasal drips?: If the cough is from post-nasal drips , then I prefer using cetirizine or fexofenadine. A better option would be a nasal steroid. However if the cough is from a sinus infection, you may then need an antibiotic; from asthma, you will need asthma medications. Best to see a doctor. ...Read more
Partially: I assume you mean hives or itchy rash from sun exposure (solar urticaria or polymorphous light eruption). Antihistamines can help treat the itch associated with the hives. If rash occurs often, taking an antihistamine daily may help. Sunscreen with uva and uvb blockers may help as well. These may not help other sun-sensitive rashes (eg, with lupus). See an allergist or dermatologist for more info. ...Read more
Zyrtec (cetirizine): Zyrtec (cetirizine) has more anti-allergy or anti-inflamatory effects than clariten (loratidine) and is often better for most allergic symptoms. It does cause drowsiness in some patients. Antihistamines work best when taken at bedtime if you are taking them on a daily basis - as in a pollen allergy or allergy to a pet that lives in your house. ...Read moreSee 1 more doctor answer
Depends: If you only have eye itching, runny nose, or sneezing, either may help but can make you groggy (especially with Benadryl). However if you have asthma or nasal congestion, you are out of luck. If the cat allergy is severe, nothing will work well with continuing exposure and allergy shots may be your best bet. ...Read moreSee 1 more doctor answer
None of these: These medications are antihistamines which counter the affects of allergies. They are not antibiotics which are typically prescribed for sinus infections. Decongestants and sinus rinses may help with the symptoms associated with the sinus infection, but these antihistamine medications, in my experience, do little for this condition. ...Read more
Need alternative to zirtec for allergy-induced asthma. Allegra and Benadryl (diphenhydramine) don't work, nor albuterol asthma inhalars. Claritin gives me nasal pain.
Allergic help: You will definitely need to speak with your physician about this. Other alternatives include the short acting chlorphenamine (chlortrimetron), sold over the counter. There are prescription medications - xyzal, singulair, xopenex, (levalbuterol) Flonase and more. Ultimately - make sure you speak with your physician about this, since the medications you have tried so far are not providing relief for you. ...Read moreSee 2 more doctor answers
Depends: The term "allergy rash" is non-specific. If it is poisen ivy or ecxema, a rash characterized by dry, scaly patches where itchiness is a major symptom then antihistamines such as Claritin or Benadryl (diphenhydramine) may be helpful. Zyrtec, in my experience, is actually better for itchiness. In more severe cases, topical or oral corticosteroids may have to be used. ...Read more
Whichever works: for you would be the best to use, although it treats only one aspect of the disease, nasal itching and runny nose ,won't affect congestion, also during an allergy season you need to take it on regular, not on as needed basis, in the end if you are not controlled you need to see an allergist ...Read more

Not typically: Benedryl helps by blocking histamine, so it is most useful for allergic problems like runny nose. It also is an effective sleep aid. It does not help much with asthma despite the fact that asthma is often allergy related. This is because of the inflammatory nature of asthma. ...Read moreSee 1 more doctor answer
