What happens if I miss a dose (Welchol)?

Take the missed dose as soon as you remember (be sure to take the medicine with food and a full glass of water). Skip the missed dose if it is almost time for your next scheduled dose. Do not take extra medicine to make up the missed dose.

What happens if I overdose (Welchol)?

Seek emergency medical attention or call the Poison Help line at 1-800-222-1222.

Because colesevelam is not absorbed into the bloodstream, an overdose of this medication is not expected to produce life-threatening symptoms. It is possible that an overdose may cause severe constipation.

What should I avoid while taking colesevelam (Welchol)?

Avoid eating foods that are high in fat or cholesterol. Colesevelam will not be as effective in lowering your cholesterol if you do not follow a cholesterol-lowering diet plan.

Do not take any other medications within 4 hours before or after you take colesevelam. Colesevelam can make it harder for your body to absorb certain other medications.

What other drugs will affect colesevelam (Welchol)?

Do not take your other medications at the same time you take colesevelam, unless your doctor has told you to. Colesevelam can make it harder for your body to absorb certain other medications.

Tell your doctor about all other medicines you use, especially:

• cyclosporine (Gengraf, Neoral, Sandimmune);
• phenytoin (Dilantin);
• a blood thinner such as warfarin (Coumadin, Jantoven);
• glyburide (DiaBeta, Glynase Presab, Micronase, Glucovance);
• thyroid hormone replacement; or
• birth control pills.

This list is not complete and other drugs may interact with colesevelam. Tell your doctor about all medications you use. This includes prescription, over-the-counter, vitamin, and herbal products. Do not start a new medication without telling your doctor.

Where can I get more information?

Your pharmacist can provide more information about colesevelam.

Remember, keep this and all other medicines out of the reach of children, never share your medicines with others, and use this medication only for the indication prescribed.
