Whether you are prescribed this medication or researching its effects, understanding its half-life, detection times, and risks is essential.

🧠 What is Quagen?

Quagen is a brand that produces promethazine hydrochloride with codeine syrup. The combination is prescribed to treat:

  • Persistent coughs

  • Allergy-related symptoms

  • Cold and flu discomfort

The promethazine hydrochloride acts as an antihistamine to relieve allergy symptoms, while codeine, an opioid, suppresses the cough reflex. Together, they form a potent formula that requires careful medical supervision.

⏳ How Long Does Quagen Stay in Your System?

Codeine in Quagen

The half-life of codeine is approximately 3 hours, meaning half the dose leaves your system in that time. However, codeine breaks down into morphine in the body, and traces of these metabolites can linger.

Promethazine in Quagen

Promethazine has a half-life of 10–19 hours, making it detectable for longer than codeine.

General Detection Windows

  • Blood tests: Detectable for 24 hours.

  • Urine tests: Detectable for 2–3 days for codeine, up to 4 days for promethazine.

  • Hair tests: Can show evidence for up to 90 days.

Note: These are general timeframes. Your results may vary.

⚑ Factors That Influence Detection Times

Several variables affect how long Quagen stays in your system:

1. Dosage and Frequency

Higher doses and frequent use extend detection times.

2. Metabolism

People with faster metabolisms eliminate codeine more quickly.

3. Hydration and Body Fat

Dehydration and higher body fat percentages can slow elimination.

4. Liver Health

As codeine is metabolized in the liver, compromised liver function can prolong its presence.
