Many people find the allergy medicine they buy at the drug store is enough to relieve their symptoms. Antihistamines like cetirizine (Zyrtec), diphenhydramine (Benadryl), fexofenadine (Allegra), and loratadine (Claritin) and olopatadine (Pataday eye drops) treat symptoms like nasal congestion, runny nose, sneezing, and itchy, watery eyes.
You can also use a saline rinse or decongestant pill, if you don’t have high blood pressure. Decongestant sprays can help unstop your nose, but you should only use them for three days.
If those don’t work, see your doctor. There are other drugs that they can prescribe to make you feel better.
