How does this medication work? What will it do for me?
5-aminosalicylic acid (5-ASA or mesalamine) belongs to the group of medications known as anti-inflammatories. It is used to treat mild-to-moderate ulcerative colitis and mild-to-moderate Crohn's disease. 5-ASA acts by reducing inflammation in the bowel.
Different brands of 5-ASA are designed to act on different places in the gastrointestinal tract (the digestion tube that runs from the mouth to the anus). Ulcerative colitis affects the colon and rectum only, while Crohn's disease affects the whole gastrointestinal tract. For this reason, some brands are used to treat only ulcerative colitis, while others can be used to treat both Crohn's disease and ulcerative colitis.
This medication may be available under multiple brand names and/or in several different forms. Any specific brand name of this medication may not be available in all of the forms or approved for all of the conditions discussed here. As well, some forms of this medication may not be used for all of the conditions discussed here.
Your doctor may have suggested this medication for conditions other than those listed in these drug information articles. If you have not discussed this with your doctor or are not sure why you are using this medication, speak to your doctor. Do not stop using this medication without consulting your doctor.
Do not give this medication to anyone else, even if they have the same symptoms as you do. It can be harmful for people to use this medication if their doctor has not prescribed it.

How should I use this medication?

Many things can affect the dose of a medication that a person needs, such as body weight, other medical conditions, and other medications. If your doctor has recommended a dose different from the ones listed here, do not change the way that you are using the medication without consulting your doctor.
It is important to use this medication exactly as prescribed by your doctor. Ulcerative colitis and Crohn’s disease never completely go away. Once a flare-up of the illness has been controlled, your doctor will recommend a smaller dose to be taken daily to reduce the chance of the symptoms from flaring up again. It is important to not stop the medication suddenly, even when you are feeling well. Doing so may cause the illness to flare up again.
If you miss a dose, take it as soon as possible and continue with your regular schedule. If it is almost time for your next dose, skip the missed dose and continue with your regular dosing schedule. Do not take a double dose to make up for a missed one. If you are not sure what to do after missing a dose, contact your doctor or pharmacist for advice.
Store all forms of this medication at room temperature, protect them from light and moisture, and keep them out of the reach of children.
Do not dispose of medications in wastewater (e.g. down the sink or in the toilet) or in household garbage. Ask your pharmacist how to dispose of medications that are no longer needed or have expired.
