1. What is Resincolestiramina and what is it used for

Resincolestiramina belongs to a group of medicines called ion exchange resins, which bind to bile acids.

• Resincolestiramina is used to decrease cholesterol levels (a type of fat) in your body that can cause heart problems. The medicine acts in the intestine by binding to bile acids that contain cholesterol, preventing their absorption and eliminating them through the feces.
• Resincolestiramina is used to treat diarrhea caused by an excess of bile acids in the intestine due to poor absorption of the same. This situation can occur in cases of Crohn's disease, intestinal resection (removal of a part of the intestine), or vagotomy (surgery of the vagus nerve) or other situations that cause an excess of bile acids in the intestine.
• Resincolestiramina can also be used to treat a specific type of itching caused by bile retention (biliary stasis).

2. What you need to know before taking Resincolestiramina

Do not take Resincolestiramina

• if you are allergic to the active substance or to any of the other components of this medicine (listed in section 6).
• if you have a disease in which your bile ducts are completely obstructed.
• if you have severe constipation.
• if you are pregnant or breastfeeding, think you may be pregnant, or plan to become pregnant.

For the treatment of diarrhea due to bile acid malabsorption, the recommended dose in adults is 4g of colestiramina (one sachet) 3 to 6 times a day (equivalent to 12-24g of colestiramina per day). Your doctor will indicate the dose to take. If you do not observe improvement within 3 days, consult your doctor.
