Welchol is used to treat high cholesterol in adults and children at least 10 years old.
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 "statin" cholesterol medications such as atorvastatin, lovastatin, simvastatin, Crestor, Lipitor, Pravachol, Zocor, and others.
Welchol is also used to improve blood sugar control in adults with type 2 diabetes. This medication is not for treating type 1 diabetes.
Welchol may also be used for purposes not listed in this medication guide.
Follow all directions on your prescription label and read all medication guides or instruction sheets. Use the medicine exactly as directed.
Take Welchol with a meal and a full glass of water or other liquid.
You may have to take several tablets at a time each time you take Welchol. Tell your doctor if you have trouble swallowing the tablet whole.
You may need to follow a special diet to prevent constipation while using Welchol. Follow all instructions of your doctor or dietitian.
Do not change the dose or timing of any other cholesterol or diabetes medications without your doctor's advice.
Welchol may increase your triglycerides (a type of fat in your blood), which can lead to pancreatitis (inflammation of the pancreas). You will need frequent blood tests.
Welchol is only part of a complete treatment program that may also include diet, exercise, and weight control. Follow your doctor's instructions very closely.
