What is Welchol?
Welchol is a cholesterol-lowering drug.
Welchol lowers "bad" cholesterol in the blood, which is also called LDL (low-density lipoprotein) cholesterol. Lowering your LDL cholesterol may reduce your risk of hardened arteries, which can lead to heart attacks, stroke, and circulation problems.
Welchol is sometimes used together with another cholesterol-lowering medication such as atorvastatin (Lipitor), fluvastatin (Lescol), lovastatin (Mevacor), pravastatin (Pravachol), rosuvastatin (Crestor), or simvastatin (Zocor).
Welchol may also be used for purposes not listed in this medication guide.
You should not take Welchol if you have a history of bowel obstruction, if you have very high levels of triglycerides (a type of fat in the blood), or if you have ever had pancreatitis caused by high triglycerides.
