Dear @Name@,

Your healthcare team has discussed the following subject with you: rifaximin. The brand name is Xifaxan. Here is some additional information. Let us know if you have any questions regarding this information.

How it works: This medication belongs to a class of drugs called antibiotics. Antibiotics are mostly used to treat infections inside the body but can be used to reduce irritation and inflammation in the intestines. Rifaximin is often used to treat irritable bowel-like symptoms (diarrhea/bloating) in the setting of IBD in adults. 

How it is taken: This medication is given as a pill.

Common side-effects: Antibiotics are generally well tolerated, but may cause side effects such as nausea, rash, diarrhea, dizziness, fatigue, itchiness, abdominal pain, and headaches. This medication may cause swelling of extremities, muscle tightening, and joint pain.

Special considerations: This antibiotic should be used with caution if taking while pregnant, especially during the first trimester.

Monitoring: No routine monitoring of labs necessary. 

Points to remember: Before taking these medications, let your healthcare team know about other medical conditions that you may have or other medications (even over-the-counter medications or complementary therapies) you may be taking.

Other tips: The best way to control your disease is by taking your medication as directed. Even when you do not have any symptoms, it is very important to continue taking your medication to prevent your disease from becoming active again. Do not alter the amount of the medication or how frequently you take it on your own. If you have any side effects or you continue to have symptoms, speak to your healthcare team immediately.
