Are Claritin (loratadine) and zyrtec the same effectiveness when use for allergic rhinitis?

Are Claritin (loratadine) and zyrtec the same effectiveness when use for allergic rhinitis?

Yes: Claritin (loratadine) and zyrtec are both oral antihistamine agents that block the effects of histamine on what is called the h1 receptor. By doing this, they reduce the release of histamine, a substance that causes itching, runny nose, and sneezing. Zyrtec blocks the receptor a bit better, but the clinical effect of the medications is roughly the same. Zyrtec may cause some drowsiness, but may last longer. ...Read more

Are there shots that can permanently alleviate my dog and cat allergies?

Are there shots that can permanently alleviate my dog and cat allergies?

Yes.: Immunotherapy - a series of injections of cat and/or dog dander under the skin over several years - will help you develop some tolerance to pet exposure. Some allergic patients respond better than others and a few patients not at all. Allergy shots alone are often not the complete answer. You may still need to get the pets off the bed, out of the bedroom, & perhaps out of the house. ...Read more

Can animal allergies cause anaphilaxis? I'm allergic to most animals but mostly cats, dogs and horses. It's very very hard to breath if i'm near them.

Rarely: Animal dander, in highly allergic people, can cause serious allergic reactions but usually the worst of it is triggering an asthma attack with cough, wheeze and shortness of breath. Animal avoidance is best but allergy shots are an excellent alternative. Possibly treating the asthma with an inhaler prior to exposure can also help. Anaphylaxis is incredibly rare to pet dander. ...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

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
