Switching between 2nd generation antihistamines seems to work for some people though there's no proof of that. In general Reactine (cetirizine), Claritin (loratidine) and Aerius (desloratidine) are all equally effective, though everyone find one that works better for them. Generic Reactine is usually the cheapest and it's what I use. First generation antihistamines are shorter lasting and make you tired, so avoid using them (Benadryl, Chlortripolon). Also, be careful with combination antihistamines ("Dual Action" or "Plus Sinus") as these contain decongestants which are stimulants and are slightly more dangerous and cannot be taken twice daily.

Remember that antihistamines are much better preventative medicine than treatment medicine, so take it daily during allergy season or it will be far less effective. They are very safe, even if taken daily

Thanks for the advice! Could you also talk about nasal spray?
