What is Quagen Pharma’s promethazine + codeine product?
The name “Quagen Pharma promethazine codeine” usually refers to a prescription combination medicine that pairs promethazine (an antihistamine with anti-nausea and sedating effects) with codeine (an opioid cough suppressant/pain medicine). This type of product is commonly prescribed for short-term treatment of cough when an opioid antitussive is considered appropriate.
If you’re looking for the exact product strength and formulation (for example, mg per mL), tell me the specific spelling you see on the label (and whether it’s a syrup or another form), and I can help narrow it down.
What is it typically used for?
Promethazine-codeine combinations are generally used for symptomatic relief of cough, and the promethazine component also adds sedation. Because codeine is an opioid, these products carry restrictions and safety warnings related to opioid risk (including dependence and breathing suppression).
What side effects do patients usually ask about?
Patients commonly ask about:
- Drowsiness, dizziness, and slowed reaction time (mainly from promethazine and codeine)
- Constipation and nausea
- Respiratory depression risk from codeine, especially at higher doses or when combined with other sedating drugs
- Misuse/addiction risk because codeine is an opioid
Avoiding alcohol and other sedatives is often emphasized for these medicines.
What should patients avoid mixing with it?
Because it contains codeine, patients are typically told to avoid combining with:
- Alcohol
- Benzodiazepines (anti-anxiety/sleep medicines)
- Other opioids
- Other sedating antihistamines or sleep aids
These combinations can increase the risk of excess sedation and slowed breathing.
Is it the same as other promethazine-codeine brands?
The active ingredients are the same across brands, but brands and manufacturers can differ in:
- Concentration/strength
- Formulation (for example, syrup concentration)
- Packaging and labeling
- Whether it’s an authorized product in a given country/market
If you share the strength (e.g., mg of promethazine and mg of codeine per mL) and the country, I can help confirm the exact match.
Where can I check regulatory status or patent-related info?
