Patient leaflet - Salofalk 250 mg tablets

1. WHAT SALOFALK 250 MG TABLETS ARE AND WHAT THEY ARE USED FOR

Salofalk 250 mg Tablets contain the active substance mesalazine, an anti-inflammatory agent used to treat inflammatory bowel disease.

Salofalk 250 mg Tablets are used for:

  • the treatment of acute episodes and prevention of further episodes (recurrence) of an inflammatory disease of the large intestine (colon), known by doctors as ulcerative colitis.

2. WHAT YOU NEED TO KNOW BEFORE YOU TAKE SALOFALK 250 MG TABLETS

Do not take Salofalk 250 mg Tablets:

  • If you are allergic to salicylic acid, to salicylates such as acetylsalicylic acid (e.g., aspirin) or to any of the other ingredients of Salofalk 250 mg Tablets (listed in section 6).
  • If you have a serious liver or kidney disease.

Warnings and precautions

Before you start taking this medicine you should tell your doctor

  • If you have a history of problems with your lungs, particularly if you suffer from bronchial asthma.
  • If you have a history of allergy to sulphasalazine, a substance related to mesalazine.
  • If you suffer with problems of your liver.
  • If you suffer with problems of your kidney.
  • If you have ever developed a severe skin rash or skin peeling, blistering and/or mouth sores after using mesalazine.

Mesalazine may produce red-brown urine discoloration after contact with sodium hypochlorite bleach in the toilet water. It concerns a chemical reaction between mesalazine and bleach and is harmless.

Further precautions

During treatment your doctor may want to keep you under close medical supervision and you may need to have regular blood and urine tests. In rare cases, in patients who have undergone bowel resection/bowel surgery in the ileo-coecal area with removal of the ileocoecal valve, it has been observed that Salofalk 250 mg Tablets are excreted undissolved in the stool, due to an excessively rapid passage through the bowel. If you notice this occurrence in your own case, please inform your doctor.

Kidney stones may develop with use of mesalazine. Symptoms may include pain in sides of abdomen and blood in urine. Take care to drink sufficient amount of liquid during treatment with mesalazine.

Serious skin reactions including drug reaction with eosinophilia and systemic symptoms (DRESS), Stevens-Johnson syndrome (SJS), and toxic epidermal necrolysis (TEN) have been reported in association with mesalazine treatment. Stop using mesalazine and seek medical attention immediately if you notice any of the symptoms related to these serious skin reactions described in section 4.

4. POSSIBLE SIDE EFFECTS

Like all medicines, this medicine can cause side effects, although not everybody gets them.

If you get any of the following symptoms after taking this medicine, you should contact your doctor and stop the intake of Salofalk 250 mg Tablets immediately:

  • General allergic reactions such as skin rash, fever, joint pain and/or breathing difficulties or a general inflammation of your large bowel (causing severe diarrhoea and abdominal pain). These reactions are very rare.
  • A marked reduction of your general health, especially if accompanied by fever, and/or a sore throat and mouth. These symptoms can, very rarely, be due to a fall in the number of white cells in your blood, which may make you more prone to developing a serious infection (agranulocytosis). Other cells of the blood may also be affected (e.g., platelets or red cells causing aplastic anaemia or thrombocytopenia) and cause symptoms which may include unexplained bleeding, purple spots or patches under your skin, anaemia (feeling tired, weak and looking pale, especially on lips and nails). A blood test can confirm whether your symptoms are due to an effect of this medicine on your blood. These reactions are very rare.
  • Serious skin rashes with reddish non-elevated, target-like or circular patches on the trunk, often with central blisters, skin peeling, ulcers of mouth, throat, nose, genitals and eyes, widespread rash, fever and enlarged lymph nodes. These can be preceded by fever and flu-like symptoms. These reactions occur in an unknown number of patients (frequency not known).
  • Shortness of breath, chest pain or irregular heartbeat, or swollen limbs which may be indicative of cardiac hypersensitivity reactions. These reactions are rare.
  • Problems with your kidney function (can occur very rarely), e.g., a change in the colour or amount of urine produced and swollen limbs or a sudden flank pain (caused by a kidney stone) (occur in an unknown number of patients (frequency not known)).
