Generic allergy pills are the exact same drug as the brand.

Generic cetirizine is Zyrtec, generic loratadine is Claritin, generic fexofenadine is Allegra: the FDA requires the identical active ingredient at the same dose. Yet the brand can cost fifteen times more per pill. So the honest way to buy allergy relief is by cost per day, not by the box you recognise. Here is every OTC option ranked by real value.

Prices reviewed 31 July 2026 . Cost per day at one standard dose, in USD; your dose may differ. Not medical advice, ask a pharmacist or doctor about what suits you.

Method: cost per day at one standard once-daily dose, from typical bulk retail prices. Generic and brand versions of each drug are the same active ingredient at the same dose and FDA-bioequivalent, so they work identically. Nasal steroid sprays are dosed differently and are most effective for congestion. Prices are indicative USD and fall further buying a large annual count.

How this works. Per day is the cost of one standard once-daily dose. The key fact: generic and brand versions of the same drug, cetirizine and Zyrtec, loratadine and Claritin, fexofenadine and Allegra, contain the identical active ingredient at the same dose and are FDA-bioequivalent, so they work exactly the same. The generic simply costs up to fifteen times less, and store brands (Equate, up&up, Amazon Basic Care) are the same drug for a hair more than bulk generic. Which drug to pick depends on symptoms: loratadine and fexofenadine are the least drowsy, cetirizine is slightly stronger but can cause mild drowsiness, and for nasal congestion a steroid spray like generic fluticasone (generic Flonase) is the most effective. Buy a large annual count for the lowest cost per dose. This is information, not medical advice, check with a pharmacist about what is right for you.
