Description: Triprolidine is an over-the-counter antihistamine with anticholinergic properties. 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. Like many antihistamines, the most common side effect is drowsiness. Triprolidine is a quick acting drug that can clear congestion and stop runny noses in 15–30 minutes. .
