Who makes promethazine (the drug)?
Promethazine is sold by multiple manufacturers under different brand names and as generics. Which exact company you’ll see depends on the product strength (for example, promethazine hydrochloride tablets, syrup, or injection) and the specific brand.
What are the common brand names and manufacturers?
In the United States, promethazine has long been available as a generic, so prescriptions are often filled by the listed generic manufacturer on the bottle rather than a single “one” manufacturer for all promethazine products.
How can you find the specific manufacturer for your promethazine?
Check the label for:
- The exact dosage form (tablet, syrup, suppository, injection)
- The strength (for example, 12.5 mg, 25 mg, etc.)
- The NDC number (National Drug Code)
You can then match the NDC to the specific manufacturer/labeler for that exact product.
If you mean promethazine by prescription vs. over the counter
Promethazine products in many places are prescription-only (depending on formulation), and the dispensing label will list the manufacturer for the product dispensed. OTC availability varies by country and by formulation.
Need the manufacturer for a specific product (NDC/brand)?
If you share either the brand name on your bottle and strength, or the NDC number, I can help identify the manufacturer that corresponds to that exact promethazine product.
