With allergy drugs such as astemizole, how about claritin (loratadine)?

Claritin (loratadine) vs Hismanal: Astemizole (hismanal) was a popular, non sedating, once a day antihistamine for allergy symptoms like runny, itchy nose, itchy eyes, sneezing etc. In some people, however it caused abnormal heart rhythm . So it was taken off the market. Seldane was another antihistamine with similar side effect. Claritin, (loratadine) Allegra and zyrtec are relatively safe.

Astemizole not sold: Astemizole is off the market as it caused arrythmias (irregular heart beats). Cetirizine is currently the most effective 2nd generation, non-sedating antihistamine available, as effective as Benadryl (diphenhydramine) 25 mg, 1 tab 3-4x/day. It can be purchased over the counter and 300-365 tabs are available from discount retailers like bj's and costco for under $18.00.
