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

Allergic rhinitis and sinusitis.  Went from loratadine claratin To Zyrtec To finally Xyzal (levocetirizine). The first 2 meds didn't help much. Is Xyzal (levocetirizine) more effective?

Allergy treatment: Basically, claritin, loratidine, zyrtec, allegra and xyzal (levocetirizine) are all 2nd generation antihistamines. If your symptoms are not controlled on these, you may need to be given intranasal steroids like flonase, nasonex or other treatments like singular, and also trying regular nasal saline. If still no improvement, time to see the allergist. ...Read more

I have horrible allergies right now (runny nose, itchy eyes, itchy throat) I took claritin (loratadine) & zyrtec they didn't work what do you suggest I try now?

Allergies: 21 year old lady with allergies unresponsive to OTC antihistamines. If blocking histamine has not worked, try using a nasal corticosteroid spray such as Flonase which you can buy over the counter. You should also try to avoid allergen triggers and visit a specialist in Rheumatology who can use an allergy panel to diagnose your specific allergy and possibly do immunotherapy. Good luck. ...Read more

Can  allergic rhinitis w/ severe post nasal drip and painful swollen l-neck gland bring on high blood press. prescription zyrtec, singulair, (montelukast) flonase, motrin?

Probably not: Allergic rhinitis is an immunological disease caused by mast cell degranulation and the release of mediators of inflammation, especially histamine. I suppose it is possible that mast cell inflammatory mediators could alter blood pressure. Also another possibility is anxiety caused by the presence of severe allergic response. In general most cases of hypertension are not caused by nasal allergy. ...Read more
