About this Medication

What the medication is used for

SALOFALK suppositories 500 or 1000 mg, are used in the management of ulcerative proctitis (inflamed rectum) and as adjunctive therapy in more extensive distal ulcerative colitis (inflammation of the lining of the large bowel and rectum).

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 a sensitivity to salicylates, for example acetylsalicylic acid (Aspirin)
  • You have stomach or small intestinal ulcers
  • You have urinary tract obstructions
  • The patient is an infant under two years of age

What the medicinal ingredient is

SALOFALK contains mesalamine (me-SAL-a-meen), also known as 5-aminosalicylic acid, 5-ASA or mesalazine.

What the non-medicinal ingredients are

SALOFALK suppositories contain Witepsol H-15 (suppository wax base). SALOFALK Suppositories are gluten-free and phthalate-free.

What dosage form it comes in

SALOFALK suppositories 500 or 1000 mg are available in strips of 6 suppositories; boxes of 30 suppositories.

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), or sulphites
  • 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 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.
