Mesalamine (patient information)

Why this medication is prescribed
Mesalamine is used to treat ulcerative colitis (a condition in which part or all of the lining of the colon [large intestine] is swollen or worn away). Mesalamine delayed-release tablets and controlled-release capsules may be used to treat ulcerative colitis that affects any part of the colon. Mesalamine suppositories and enemas should only be used to treat inflammation of the lower part of the colon. Mesalamine is in a class of medications called anti-inflammatory agents. It works by stopping the body from producing a certain substance that may cause pain or inflammation.

How this medication should be used
Mesalamine comes as a delayed-release tablet and a controlled-release capsule to take by mouth and as a suppository and an enema to use in the rectum. The delayed-release tablet is usually taken three times a day, and the controlled-release capsule is usually taken four times a day. The suppository is usually used one to three times a day, and the enema is usually used once a day at bedtime. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take or use mesalamine exactly as directed. Do not take or use more or less of it or take or use it more often than prescribed by your doctor.

Swallow the tablets whole; do not split, chew, or crush them. Be careful not to break the protective coating on the tablets.

If you are unable to swallow the capsules, you may mix the contents of the capsules with water. Open a capsule and sprinkle all of the beads it contains in a small glass of water. Stir the beads into the water and drink the mixture right away. Do not store mixtures of beads and water for later use.

The enema and suppositories are for rectal use only.

You should begin to feel better during the first few days or weeks of your treatment with mesalamine. Continue to take or use mesalamine until you finish your prescription, even if you feel better at the beginning of your treatment. Do not stop taking or using mesalamine without talking to your doctor.

Mesalamine suppositories and enemas may stain clothing, flooring, fabric and other surfaces. Take precautions to prevent staining when you use these medications.

If you are to use the enema, follow these steps:


 * 1) Try to have a bowel movement. The medication will work best if your bowels are empty.
 * 2) Use a scissors to cut the seal of the protective foil pouch that holds seven bottles of medication. Be careful not to squeeze or cut the bottles. Remove one bottle from the pouch.
 * 3) Look at the liquid inside the bottle. It should be off-white or tan colored. The liquid may darken slightly if the bottles are left out of the foil pouch for a time. You may use liquid that has darkened a little bit, but do not use liquid that is dark brown.
 * 4) Shake the bottle well to make sure the medication is mixed.
 * 5) Remove the protective cover from the applicator tip. Be careful to hold the bottle by the neck so that the medication will not leak out of the bottle.
 * 6) Lie on your left side with your lower (left) leg straight and your right leg bent toward your chest for balance. You can also kneel on a bed, resting your upper chest and one arm on the bed.
 * 7) Gently insert the applicator tip into your rectum, pointing it slightly toward your navel (belly button). If this causes pain or irritation, try putting a small amount of personal lubricating jelly or petroleum jelly on the tip of the applicator before you insert it.
 * 8) Hold the bottle firmly and tilt it slightly so that the nozzle is aimed toward your back. #Squeeze the bottle slowly and steadily to release the medicine.
 * 9) Withdraw the applicator. Remain in the same position for at least 30 minutes to allow the medicine to spread through your intestine. Try to keep the medicine inside of your body for about 8 hours (while you sleep).
 * 10) Throw away the bottle in a trash can that is out of the reach of children and pets.Each bottle contains only one dose and should not be reused.

If you are to use the suppository, follow these steps:


 * 1) Try to have a bowel movement just before using the suppository. The medication will work best if your bowels are empty.
 * 2) Separate one suppository from the strip of suppositories. Hold the suppository upright and use your fingers to peel off the plastic wrapper. Try to handle the suppository as little as possible to avoid melting it with the heat of your hands.
 * 3) You may put a small amount of personal lubricant jelly or Vaseline on the tip of the suppository so that it will be easier to insert.
 * 4) Lie down on your left side and raise your right knee to your chest. (If you are left-handed, lie on your right side and raise your left knee.)
 * 5) Using your finger, insert the suppository into the rectum, pointed end first. Use gentle pressure to insert the suppository completely. Try to keep it in place for 1-3 hours or longer if possible.
 * 6) Wash your hands thoroughly before you resume your normal activities.
