Aminosalicylate Sodium (Oral)

Aminosalicylate sodium is taken to treat, prevent, control, and improve medical conditions like tuberculosis (TB), ulcerative colitis, and Crohn's disease.


Aminosalicylate sodium is taken together with other medicines to treat tuberculosis (TB). Active tuberculosis treatment requires taking several medicines together for at least 6 months. Aminosalicylate sodium may be taken as part of that combined drug treatment. Aminosalicylate sodium is also referred to as anti-tuberculosis antibiotic. It works to stop or slow down bacterial growth.

This antibiotic only treats bacterial infections. It won't treat viral infections, including flu, common cold, etc. Misuse or unnecessary use of any antibiotic may make it less effective.

Don't take Aminosalicylate sodium if the granules have become purple or dark brown or if the pack is swollen. This may indicate that the medicine hasn't been stored properly. For storage directions, turn to the storage section.

Take this medicine by mouth, usually twice or thrice every day as instructed by your physician. This medication must be taken together with acidic food to work properly in your body. Simply open the pack and sprinkle the dose onto any acidic food like juice (e.g. tomato, orange, grape, grapefruit, cranberry, punch, and apple juice), applesauce, or yogurt. Don't mix it in other types of food. If you mix the granules with juice, stir the mixture and drink it immediately. The granules won't dissolve in the mixture. Don't chew or crush the granules prior to or while swallowing. Also don't prepare a dose in advance. If you've got questions about how this medication should be taken, talk to your physician or pharmacist.

Aminosalicylate sodium dosing will depend on your response to treatment, age, and medical condition.

For the best outcome, take this medication at evenly spaced intervals. To serve as a reminder, take this medicine at the same time each day.

Continue to take Aminosalicylate sodium until you finish the whole prescribed amount, even if your symptoms fade away after some days. Discontinuing the medicine too early may cause the infection to return.

Talk to your physician if your medical condition doesn't get better or if it becomes worse.
