Quagen Promethazine Hydrochloride and Codeine Phosphate Oral Solution

Quagen Promethazine Hydrochloride and Codeine Phosphate Oral Solution is a high-quality, prescription-strength cough suppressant and antihistamine combination designed for fast, effective relief of cough, throat irritation, and upper respiratory tract symptoms. Manufactured by Quagen Pharmaceuticals, a trusted U.S.-based pharmaceutical company, this oral solution delivers dual-action symptom control through its two active ingredients: Promethazine HCl and Codeine Phosphate.

This medication is commonly used for the short-term treatment of coughs caused by colds, flu, or allergies, especially when the cough is severe, dry, or disrupting sleep. The syrup format ensures fast absorption, making it one of the most effective solutions for cough relief on the market.

What is Quagen Promethazine Codeine Oral Solution Used For?

Quagen’s syrup is indicated for individuals experiencing:

Dry or unproductive coughs
Allergic reactions involving the throat and sinuses
Cold and flu symptoms involving persistent coughing
Bronchial irritation or post-nasal drip
Throat inflammation and difficulty sleeping due to coughing

By combining Codeine, a centrally-acting opioid cough suppressant, with Promethazine, a sedative antihistamine, this solution offers powerful relief that works fast and lasts for hours.

How It Works

Promethazine HCl (6.25 mg per 5 mL): Blocks histamine receptors to relieve allergy symptoms such as sneezing, runny nose, and itchiness. It also contributes to the sedative effects that help users rest while recovering.
Codeine Phosphate (10 mg per 5 mL): Works on the brain’s cough center to reduce the urge to cough. It also has mild pain-relieving effects, making it ideal for coughs that cause throat pain or strain.

This formulation ensures both symptomatic relief and improved rest, especially during nighttime hours.
