This is a chronic condition that will probably recur every year, perhaps for a lifetime. Therefore, it is important to learn how to control it. The best drug for hay fever is an antihistamine. It will relieve nose and eye symptoms. You need the antihistamine recommended by your physician.
Symptoms clear up faster if antihistamines are given at the first sign of sneezing or sniffing.
For people with occasional symptoms, antihistamines can be taken on days when symptoms are present or expected. The main side effect of antihistamines is drowsiness. If you remain drowsy, continue the drug, but temporarily decrease the dosage. You should become tolerant of the regular dosage in 1 to 2 weeks. If antihistamines only give partial relief of symptoms, severe hay fever can usually be controlled by new cromolyn or steroid nasal sprays.
