    • What is this medication and its most common uses?

      Welchol is a medicine used along with diet and exercise to treat high cholesterol levels in the blood by lowering "bad" low-density lipoprotein (LDL) cholesterol. Welchol is also used along with diet and exercise to help control high blood sugar in adults with type 2 diabetes. Welchol is available as tablets and a powder for oral suspension.

    • What should I know when beginning and continuing on this medication?

      How does this medication work?

      Bile acids are made when cholesterol is broken down in your body. Welchol works by binding to bile acids in your intestines, thereby lowering your cholesterol levels.

      What are the beneficial effects of this medication and when should I begin to have results?

      What:

      Diabetes: Studies show that Welchol, when added to certain diabetes medicines, helped lower A1C levels (an estimate of your average blood sugar levels over a 2- to 3- month period). Lowering your blood sugar to a normal level may prevent or delay potential complications associated with diabetes, such as blindness, kidney failure, or heart problems.

      Cholesterol: In two different studies, when added to 10 mg each of simvastatin and atorvastatin, Welchol lowered LDL cholesterol by 42% and 48% respectively.

      When: Everyone responds differently to treatment, so try to be patient and follow your healthcare provider's directions. Though you may not feel an improvement or change in the way you feel, it is very important to keep taking your medicine as prescribed to keep your condition under control.

      How do I know it is working?

      Your healthcare provider may do blood tests to check your cholesterol, blood sugar, and your A1C levels during treatment with Welchol. Appropriate diet and exercise also contribute to your overall heart health and will also affect the results of your blood tests.

      Taking Welchol is not a substitute for following a healthy low-fat and low-cholesterol diet and exercising to lower your cholesterol.

    • What are the possible side effects of this medication?

      The following is not a full list of side effects. Side effects cannot be anticipated. If any develop or change in intensity, tell your healthcare provider as soon as possible. Only your healthcare provider can determine if it is safe for you to continue taking this medication.

      More common side effects may include: constipation, upset stomach, nausea.

      Less common side effects may include:

      Welchol may increase triglyceride (a type of fat in the blood) levels.

    • Who should not take this medication?

      Do not take Welchol if you are allergic to it or any of its ingredients.

      Do not take Welchol if you have had a blockage in your intestines or inflammation of your pancreas associated with high triglyceride levels.

      Do not take Welchol if you have very high triglyceride levels in your blood.

    • What should I tell my healthcare provider before I take the first dose of this medication?

      Tell your healthcare provider about all prescription, over-the-counter, and herbal medications you are taking before beginning treatment with Welchol. Also, talk to your healthcare provider about your complete medical history, especially if you have problems with your stomach or intestines; problems swallowing; or a condition called phenylketonuria (an inability to process phenylalanine, a protein in your body).

    • What is the usual dosage?
