About this Medication

What the medication is used for

SALOFALK tablets are used for the treatment of acute ulcerative colitis (inflammation of the lining of the large bowel and rectum) and in the prevention of relapse of Crohn’s disease in patients following bowel resection.

What it does

SALOFALK is believed to work by interfering in the activity of certain mediators of inflammation (e.g., prostaglandins) which helps reduce the inflammation (swelling and pain) in the rectum and lower part of the large bowel.

When it should not be used

SALOFALK should not be used if:

  • patients with severe kidney (renal) impairment (GFR<30ml/min/1.73m2) and/or severe liver (hepatic) impairment (see WARNINGS AND PRECAUTIONS).
  • You are allergic to mesalamine or to any ingredient in the formulation (see What the non-medicinal ingredients are)
  • You have stomach or small intestinal ulcers
  • You have urinary tract obstructions
  • You have a sensitivity to salicylates, for example acetylsalicylic acid (Aspirin)
  • You are unable to swallow the intact tablet
  • The patient is an infant under two years of age

What the medicinal ingredient is

SALOFALK tablets contain 500 mg mesalamine (me-SALa-meen), also known as 5-aminosalicylic acid, 5-ASA or mesalazine.

What the non-medicinal ingredients are

SALOFALK tablets contains carnauba wax, colloidal silicon dioxide, glycine, hydroxypropyl methylcellulose, iron oxide, magnesium stearate, methacrylic acid copolymer, microcrystalline cellulose, polydimethyl siloxane, polysorbate, povidone, sodium carbonate, sodium hydroxide, talc, titanium dioxide, triethyl citrate. SALOFALK® tablets are gluten-free and phthalate-free.

What dosage form it comes in

SALOFALK 500 mg tablet is available for oral administration as an ochre-coloured (pale yellow), oblong, enteric-coated tablet.

SALOFALK 500 mg tablet is supplied in bottles of 150 and 500.

Warnings and Precautions

BEFORE you use SALOFALK talk to your doctor or pharmacist if:

  • You have a pre-existing liver disease. There have been reports of liver (hepatic) failure and increased liver enzymes in patients treated with 5-ASA or mesalazine (=mesalamine) products.
  • You have mild to moderate liver function impairment. Your doctor will decide if this product is right for you.
  • You ever had any unusual or allergic reaction to mesalamine (5-ASA), sulfasalazine (SAS), salicylates (Aspirin)
  • You have liver or kidney disease
  • You have bleeding or clotting disorders
  • Your doctor has said you have higher than normal blood urea nitrogen (BUN) levels (renal function test)
  • You have pyloric stenosis (a narrowing of the outlet from the stomach that causes contents of the stomach to remain there for a longer period of time). Pyloric stenosis may keep the SALOFALK tablet from reaching the colon as quickly as it normally would
  • You are pregnant or breastfeeding. Mesalamine is excreted in human breast milk. Discuss with your doctor.


  • Discontinue use at first sign of rash or fever.

You may have your blood or urine tested regularly to monitor your kidney function since prolonged use of SALOFALK may damage your kidneys.

Interactions with this Medication

Interaction between azathioprine, 6-mercaptopurine, and aminosalicylates (such as SALOFALK) has been reported.

Drug interactions with coumarin, methotrexate, probenecid, sulfinpyrazone, spironolactone, furosemide, rifampicin, and Varicella Virus Vaccine (chicken pox vaccine) may bepossible.

Possible interference with measurements, by liquid chromatography, of urinary normetanephrine causing a false-positive test result have been observed in patients exposed to sulfasalazine or its metabolite, mesalamine/mesalazine.

Proper Use of this Medication

For the treatment of acute ulcerative colitis: Two 500 mg SALOFALK tablets, three or four times daily.
