Important Information About Welchol

Welchol lowers LDL or "bad" cholesterol along with diet and exercise. It can be taken alone or with other cholesterol-lowering medications known as statins.

Welchol, along with diet and exercise, also lowers blood sugar levels in patients with type 2 diabetes mellitus when added to other antidiabetic medications (metformin, sulfonylureas, or insulin).

Ask your doctor if Welchol is right for you.

Welchol is not for everyone, especially those with intestinal blockage, those with blood triglyceride levels of greater than 500 mg/dL, or a history of pancreatitis (inflammation of the pancreas) due to high triglyceride levels.

Welchol has not been shown to prevent heart disease or heart attacks.

Tell your doctor if you have high triglycerides (greater than 300 mg/dL).

Tell your doctor if you have stomach or intestinal problems, including gastroparesis (when the stomach takes too long to empty its contents), abnormal contractions of the digestive system, major gastrointestinal tract surgery, or if you have trouble swallowing.

Tell your doctor if you have vitamin A, D, E, or K deficiencies.

Welchol has known interactions with glyburide (a drug for diabetes), levothyroxine (a drug used to treat an underactive thyroid) and certain oral contraceptives. Welchol has not been studied with all combinations of drugs and supplements. Please tell your doctor about all medications and supplements you may be taking before beginning Welchol, as your doctor may tell you to take your other medications and supplements 4 hours before taking Welchol.

Remember to tell your doctor if you are pregnant, plan to become pregnant, or are breastfeeding.
