PrescriptionsBest OTC Allergy Medicines 2023 and When to Take Them
OTC allergy medications come in various types, including antihistamines like cetirizine (Zyrtec), loratadine (Claritin), and fexofenadine (Allegra); decongestants such as pseudoephedrine (Sudafed) and phenylephrine (Neo-Synephrine); nasal steroids like fluticasone (Flonase) and budesonide (Rhinocort); and eye drops containing ketotifen (Zaditor). Generic drugs are as effective as brand-name options and more affordable. Antihistamines should be taken before allergen exposure for optimal results. Onset times vary: antihistamines (20 minutes to 3 hours), decongestants (15 minutes to 1 hour), nasal steroids (a few hours, best after several days), and eye drops (within minutes).
