My doctor suggested I try benadryle , Zyrtec or claritin , but they just dry my eyes even more.Even though I find relieve from my allergies my eyes become more irritated and bloodshot. Another reason I stopped taking Zyrtec and Claritin is because I became more agitated and restless when trying to sleep.From my research online many have experienced similar side effects.I've even tried the neti pot but that relieve is short lived. Is their anything that can relieve post nasal drip but at same time won't dry eyes out.
