Triprolidine is an over-the-counter first-generation antihistamine with strong anticholinergic properties.[1] It is used to combat the symptoms associated with allergies and is sometimes combined with other medications in preparations designed to provide general relief for flu-like symptoms.[2] As with many antihistamines, the most common side effect is drowsiness.[1]
Triprolidine was patented in 1948 and came into medical use in 1953,[3] and has mostly been replaced in popular cold and flu medications by other drugs such as diphenhydramine, promethazine, chlorpheniramine, loratadine and fexofenadine.
