Is there any reaction if I took telfast 180mg at 1pm and now at 10pm polarine for my flu?

DrugDrug interaction. Check out www.Epocrates.Com & www.Drugs.Com for any drug/medication related questions you might have, including side effects & drug-drug interactions. Try to figure out generic names b/c same drug sold under different brand names in other countries. Telfast in malaysia = Allegra in states = fexofenadine. Many different versions of polarine. Should be fine but ask your doc & pharmacist to be sure.
