Mesalamine is a prescription medication used to treat ulcerative colitis, or inflammation of the lining of the colon. It helps relieve the symptoms of ulcerative colitis including diarrhea, rectal bleeding, and stomach pain. Mesalamine belongs to a group of drugs called aminosalicylates.

Mesalamine is a prescription medication used to treat ulcerative colitis (UC). UC is a condition in which part or all of the lining of the colon (also known as the large intestine) is swollen or worn away. It is used to cause the disease to temporarily go away ("induce remission") and to keep it from coming back ("maintain remission").

This medication may be prescribed for other uses. Ask your doctor or pharmacist for more information.

Oral/Topical:

Serious side effects have been reported with mesalamine including:

• Kidney problems. Tell your doctor if you take non-steroidal anti-inflammatory drugs or have kidney disease. Your doctor will check your kidney function with a simple blood test before you start taking mesalamine.
• Mesalamine may worsen ulcerative colitis. Tell your doctor if you experience the following symptoms:
  • cramping
  • acute abdominal pain
  • bloody diarrhea
  • fever
  • headache
  • rash
• Hypersensitivity reaction. An allergic reaction is possible with mesalamine. Tell your doctor if you are allergic to sulfasalazine (Azulfidine) or mesalamine. Serious reactions can lead to heart problems, like myocarditis or pericarditis.
• Liver failure is possible with mesalamine. Tell your doctor if you have liver disease.
• Upper GI tract obstruction. Pyloric stenosis or an obstruction in the digestive tract could prevent mesalamine from reaching the colon and treating ulcerative colitis.
• Pericarditis (inflammation of the lining around the heart). Tell your doctor if you experience symtoms of pericarditis including chest pain, rapid heartbeat, difficulty breathing, and fever. Your doctor may want to temporarily stop use of mesalamine.

This is not a complete list of mesalamine side effects. Ask your doctor or pharmacist for more information.

Call your doctor for medical advice about side effects. You may report side effects to the FDA at 1-800-FDA-1088.

Tell your doctor about all the medicines you take including prescription and non-prescription medicines, vitamins, and herbal supplements. Especially tell your doctor if you take:

• medicines that can damage the kidneys, including non-steroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen (Advil) and aspirin (Ecotrin)
• azathioprine (Imuran)

This is not a complete list of mesalamine drug interactions.  Ask your doctor or pharmacist for more information.

Tell your doctor if you are pregnant or plan to become pregnant.  

The FDA categorizes medications based on safety for use during pregnancy. Five categories – A, B, C, D, and X, are used to classify the possible risks to an unborn baby when a medication is taken during pregnancy.

Mesalamine falls into category B. Studies in animals have failed to demonstrate a risk to the unborn baby and there are no well-controlled studies in pregnant women.

Tell your doctor if you are breastfeeding or plan to breastfeed. The active ingredient in mesalamine is excreted in human breast milk. The effect of mesalamine on the nursing infant is not known.

Do not to take mesalamine with antacids, because it could affect the way mesalamine works.

Continue to take mesalamine until you finish your prescription set by your doctor, even if you feel better at the beginning of your treatment.

Tell your doctor if you have phenylketonuria (PKU, an inherited condition), because the extended release capsules contains aspartame that forms phenylalanine.
