Overview
Prolidin 1.25mg/30mg Syrup is a combination antihistamine-decongestant syrup, each 5mL dose containing triprolidine hydrochloride 1.25mg and pseudoephedrine hydrochloride 30mg. It is used for the short-term relief of allergic rhinitis and common cold symptoms such as sneezing, runny or itchy nose, watery eyes, and nasal congestion.
Triprolidine is a sedating antihistamine that blocks histamine H1 receptors to relieve sneezing, itching, and watery eyes/nose, while pseudoephedrine is a decongestant that narrows swollen blood vessels in the nasal passages to relieve stuffiness, so the combination addresses both the allergic and congestive components of these symptoms.
How it Works
Triprolidine competitively blocks histamine at H1 receptors, preventing histamine released during an allergic reaction from causing sneezing, itching, and increased nasal/eye secretions; being a sedating antihistamine, it also crosses into the brain, which contributes to drowsiness. Pseudoephedrine stimulates alpha-adrenergic receptors in nasal blood vessels, causing them to constrict and reducing the swelling and mucus production that cause nasal congestion.
Directions for Use
Measure Prolidin 1.25mg/30mg Syrup using the dosing cup or oral syringe provided, rather than a household spoon, and take it with a drink of water if desired. This syrup formulation is commonly used for children as well as adults who have difficulty swallowing tablets – a doctor or pharmacist should determine the exact dose for a child based on their specific age and body weight, as this varies and should not be guessed.
Dosage
Prolidin 1.25mg/30mg Syrup is dosed by volume (per 5mL) according to age, taken several times a day as directed on the label or by your doctor/pharmacist, for the shortest time needed to relieve symptoms. Because the syrup is often given to children, always use the measuring device provided and follow the exact dose determined for the individual by a doctor or pharmacist – never estimate a child’s dose yourself.
