In brief: Decongestants

Most allergy medicines contain antihistamines, decongestants or a combination of the two.
Antihistamines help runny, watery or itchy nose or eyes. Decongestants help congestion and stuffiness. Allegra, claritine and zyrtec are pure antihistamines. Allegra d, Claritin (loratadine) d and zyrtec d contain pseudo Ephedrine ( sudafed).). 'd' stands for decongestant. At night it can keep you awake.
