Why is this medication prescribed?

Sulfasalazine is used to treat ulcerative colitis, a disorder that results in swelling and ulcers on the rectum and colon (large intestine) lining, as well as to maintain symptom relief. Adults with rheumatoid arthritis who have not responded well to conventional drugs or who could not tolerate them are also treated with sulfasalazine delayed-release (Azulfidine EN-tabs). In children who have not responded to other medications, sulfasalazine delayed-release (Azulfidine EN-tabs) is also used to treat polyarticular juvenile idiopathic arthritis (PJIA), a type of childhood arthritis that affects five or more joints during the first six months of the condition and causes pain, swelling, and loss of function. Sulfasalazine belongs to the group of pharmaceuticals known as anti-inflammatory drugs. It reduces swelling and inflammation inside the body.

How should this medicine be used?

Both standard and delayed-release sulfasalazine tablets are available; the latter releases the drug in the intestine rather than the stomach, preventing stomach discomfort and enabling the drug to exert its effects there. It is often taken 3 to 6 times a day, evenly spaced out throughout the day so that, wherever possible, no more than 8 hours pass between any two doses. Sulfasalazine delayed-release tablets are often given twice daily in doses spread equally throughout the day to treat polyarticular juvenile idiopathic arthritis or rheumatoid arthritis. Sulfasalazine should be taken with a meal or light snack and followed by a full glass of water.Ask your doctor or pharmacist to explain any instructions on your prescription label that you are unsure about following. Sulfasalazine should be taken as prescribed. Never take it in larger or less amounts or more frequently than directed by your doctor.

Do not crush or chew delayed-release pills; instead, swallow them whole.

Be sure to stay hydrated while taking sulfasalazine.

Even if you feel well, keep taking the sulfasalazine medication. Without consulting your doctor, do not stop taking sulfasalazine.

Other uses for this medicine

Sulfasalazine is also used to treat Crohn’s disease-related stomach pain, colon inflammation, diarrhoea (frequent stools), and rectal bleeding. Discuss the potential dangers of using this medication for your illness with your doctor.

What should I know about storage and disposal of this medication?

Keep this medication tightly closed in the original container and out of the reach of children. Store it away from excessive heat and moisture at room temperature (not in the bathroom).

Unused prescriptions must be disposed of carefully to prevent pets, kids, and other people from ingesting them. You should not, however, dispose of this medication in the toilet. Instead, utilising a medicine take-back programme is the easiest approach to get rid of your medication. To find out about take-back programmes in your area, speak with your pharmacist or the garbage/recycling department in your city. If you do not have access to a take-back programme, see the FDA’s Safe Disposal of Medicines website at http://goo.gl/c4Rm4p for additional information.

As many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and are simple for young children to open, it is crucial to keep all medications out of sight and out of reach of children. Always lock safety caps and promptly stash medication up and away from young children where it is out of their sight and reach to prevent poisoning. http://www.upandaway.org
