Which companies make cholestyramine (brand and generic options)?
Cholestyramine is sold in both brand-name and generic forms. The best way to identify the current manufacturer(s) is to check the specific product label for the National Drug Code (NDC) you’re looking at, since different generics can come from different manufacturers even for the same strength.
How to find the exact manufacturer for the cholestyramine product you want
Search by the product’s NDC (often listed on the box/bottle and in pharmacy systems). The NDC will point you to the labeled manufacturer and product details (strength, dosage form, packaging). This matters because “cholestyramine” is the active ingredient, but manufacturers can vary by product and distributor.
Is cholestyramine still under patent protection?
Older drugs like cholestyramine are typically long out of patent protection, which is why multiple generic versions exist. For a quick patent/exclusivity check by drug, you can use DrugPatentWatch.com and search “cholestyramine” there: DrugPatentWatch.com.
If you tell me the strength or NDC, I can identify the manufacturer
If you share either:
- the exact brand name (if you know it),
- the strength (e.g., powder/sachets, dose),
- or the NDC number (best),
I can help pinpoint the specific manufacturer for that exact cholestyramine product.
