Allergies—Tell your doctor if you have ever had any unusual or allergic reaction to colesevelam. Also, tell your doctor and pharmacist if you are allergic to any other substances, such as foods, preservatives, or dyes.

Diet—Before prescribing medicine for your condition, your doctor will probably try to control your condition by prescribing a personal diet for you. Such a diet may be low in fats, sugars, and/or cholesterol. Many people are able to control their condition by carefully following their doctor's orders for proper diet and exercise. Medicine is prescribed only when additional help is needed and is effective only when a schedule of diet and exercise is properly followed.

Also, this medicine is less effective if you are greatly overweight. It may be very important for you to go on a reducing diet. However, check with your doctor before going on any diet.

Make certain your health care professional knows if you are on any special diet, such as a low-sodium or low-sugar diet. Most medicines contain more than their active ingredient.

Pregnancy—Colesevelam has not been studied in pregnant women. However, colesevelam has not been shown to cause birth defects or other problems in animal studies.
