Welchol Suspension is used for:
Reducing high cholesterol levels. It is used along with diet and exercise. It may be used alone or with other medicines. It is also used along with other medicines to control blood sugar in patients with type 2 diabetes.
Welchol Suspension is a bile acid sequestrant. It works to decrease cholesterol by increasing the removal of bile acids from the body. As the body loses bile acids, it replaces them by converting cholesterol from the blood to bile acids. This causes the blood level of cholesterol to decrease. Exactly how it works to treat type 2 diabetes is not known.
Do NOT use Welchol Suspension if:
- you are allergic to any ingredient in Welchol Suspension
- you have a history of certain bowel problems (eg, blockage, paralysis, slow movement of the bowel muscles) or major stomach or bowel surgery, or you are at risk of bowel blockage
- you have very high triglyceride levels or a history of inflammation of the pancreas (pancreatitis) caused by high triglyceride levels
- you have type 1 diabetes or diabetic ketoacidosis
Contact your doctor or health care provider right away if any of these apply to you.

- Diabetes patients - Carry an ID card at all times that says you have diabetes. Check your blood sugar levels as directed by your doctor. If they are often higher or lower than they should be and you take Welchol Suspension exactly as prescribed, tell your doctor.
- Diabetes patients - Welchol Suspension may lower your blood sugar levels. Low blood sugar may make you anxious, sweaty, weak, dizzy, drowsy, or faint. It may also make your heart beat faster; make your vision change; give you a headache, chills, or tremors; or make you more hungry. It is a good idea to carry a reliable source of glucose (eg, tablets or gel) to treat low blood sugar. If this is not available, you should eat or drink a quick source of sugar like table sugar, honey, candy, orange juice, or non-diet soda. This will raise your blood sugar level quickly. Tell your doctor right away if this happens. To prevent low blood sugar, eat meals at the same time each day and do not skip meals.
- Lab tests, including cholesterol, triglyceride, and blood glucose levels, may be performed while you use Welchol Suspension. These tests may be used to monitor your condition or check for side effects. Be sure to keep all doctor and lab appointments.

- PREGNANCY and BREAST-FEEDING: If you become pregnant, contact your doctor. You will need to discuss the benefits and risks of using Welchol Suspension while you are pregnant. It is not known if Welchol Suspension is found in breast milk. If you are or will be breast-feeding while you use Welchol Suspension, check with your doctor. Discuss any possible risks to your baby.
