Does Claritin Offer Relief From Post Nasal Drip?

Methods of post-nasal drip treatment include antibiotics, antihistamines, decongestants and thinning the mucus, explains WebMD. In addition, flushing out excess mucus and irritants with a saline nasal spray can help relive a post-nasal drip. Older antihistamines, such as Benadryl, can actually thicken mucus as a result of drying it. Newer antihistamines, such as Claritin, Allegra and Zyrtec may be better options and are less likely to cause drowsiness.
