Triprolidine is an over-the-counter antihistamine with anticholinergic properties.^[1] It is used to combat the symptoms associated with allergies and is sometimes combined with other cold medications designed to provide general relief for flu-like symptoms.^[2] As with many antihistamines, the most common side effect is drowsiness.^[1]

It was patented in 1948 and came into medical use in 1953.^[3]
