1. What Pentasa 4 g is and what it is used for

Pentasa 4 g is indicated for the treatment of mild to moderate ulcerative colitis flare-ups and to help maintain you free of new flare-ups.

Ulcerative colitis is an inflammatory bowel disease in which the lining of the intestine is inflamed and develops many small breaks in its surface (ulcers) that can bleed.

Pentasa 4 g contains granules that slowly release the active ingredient (mesalazine). This helps to reduce inflammation and painful symptoms.

2. What you need to know before you take Pentasa 4 g

Do not take Pentasa 4 g

  • if you are allergic (hypersensitive)to mesalazineor to any of the other components of this medicine (see section 6)
  • if you are allergicto other salicylates, for example, acetylsalicylic acid
  • if you have severe kidney and/or liver problems

Warnings and precautions

  • if you are on treatmentthat may affect kidney function, for example, non-steroidal anti-inflammatory drugs (NSAIDs) such as aspirin
  • if you have lung problems, asthma in particular
  • treatment with Pentasa should be interrupted immediately in case of abdominal cramps, abdominal pain, fever, severe headache, and rash

  • If you have ever suffered from a severe skin rash, skin peeling, blisters, or sores in the mouth after using mesalazine.

Mesalazine may cause a discoloration of the urine to a reddish-brown color after contact with sodium hypochlorite bleach in the toilet water. This is a chemical reaction between mesalazine and bleach and is harmless.

Be careful with mesalazine:

Severe skin reactions, including drug reaction with eosinophilia and systemic symptoms (DRESS), Stevens-Johnson syndrome (SSJ), and toxic epidermal necrolysis (NET), have been observed with mesalazine treatment. Stop taking mesalazine and seek medical attention immediately if you notice any of the symptoms related to these severe skin reactions described in section 4.

While you are on treatment with this medicine, your doctor will normally perform blood and urine tests to monitor your kidney function, especially at the start of treatment.
