Do antihistamines like Benadryl (diphenhydramine) help prevent oral allergy syndrome?

Do antihistamines like Benadryl (diphenhydramine) help prevent oral allergy syndrome?

Probably not: Oral allergy syndrome is usually caused by pollens and sometimes nuts. Claritin, zyrtec and Allegra (fexofenadine) can help with pollen allergies. But like any other allergy, it is best to stay away from the problem. Have an allergist test you and see what treatment would be best. ...Read more

What is the best allergy treatment for eyes I mean the best eye drops for allergy. Not over-the-counter drugs. Oral antihistamine alone not helping.

What is the best allergy treatment for eyes I mean the best eye drops for allergy. Not over-the-counter drugs. Oral antihistamine alone not helping.

Patanol (olopatadine): I prefer patanol (olopatadine) drops. There are others which are similar. The important thing is to wash your face with a cool wash cloth before applying to remove any lingering allergens from your facial skin and around your eyes. This helps my patients a great deal. If you're not better with drops see an allergist for testing, you may want to consider allergy shots. ...Read more

If i've conjunctivitis allergy, can it heal by allergy injection therapy ?Tried allergy meds : allegysal, patanol (olopatadine) and avil, Claritin loratadine, please help

Yes: Treatment of allergic conjunctivitis starts with eliminating or avoiding the allergen as well as rinsing the allergen from your eyes with plain water (reduces the allergen load). Allergy shots can help as can oral allergy meds. There are eye drops that help a great deal also. Steroid eye drops are very effective but are not used long term due to risk of glaucoma and cataract. ...Read more

Zyrtec, claritin, (loratadine) allegra, clarinex. Other allergy pill options? Year-round, persistant allergies. Wet in ears, post-nasal drip (sore throat).

Zyrtec, claritin, (loratadine) allegra, clarinex. Other allergy pill options? Year-round, persistant allergies. Wet in ears, post-nasal drip (sore throat).

Before you go : Looking for another allergy medication, i would keep the one that works best for you and take it diligently everyday with a steroid nasal spray twice daily for a month to see a big difference with just burst of meds here and there and only when you feel like it. If you have already done this, then it is time to see your doctor, possibly referral to allergist or ENT depends on what the problem is. ...Read more

Allergy shots or antihistamine pills which works better?

Allergy shots: antihistamines only cover up symptoms and don't cure anything. Allergy shots treat the cause and that is why with successful immunotherapy you can get rid of antihistames.
