1. What Pentasa is and what it is used for
Mesalazine, the active substance in Pentasa, exerts a local anti-inflammatory effect on the diseased wall of the small and large intestine. Mesalazine is released continuously from the granules along the entire length of the intestine, regardless of pH value.
Pentasa is used in the treatment of mild to moderate ulcerative colitis and Crohn's disease.
2. Important information before using Pentasa
BEFORE STARTING MESALAZINE TREATMENT, INFORM YOUR DOCTOR IF:
- The patient has ever experienced severe skin rash, skin peeling, blisters, or oral ulcers after taking mesalazine.

Warnings and precautions

- The patient has liver and/or kidney function disorders,

- The patient has lung disorders, particularly bronchial asthma,
- The patient experiences severe or recurrent headache, visual disturbances, or ringing or buzzing in the ears – in such cases, contact your doctor immediately.
Mesalazine treatment may lead to the formation of kidney stones. Symptoms may include flank pain and haematuria. Adequate fluid intake is recommended during mesalazine therapy.
Serious skin reactions have been reported with mesalazine treatment, including drug reaction with eosinophilia and systemic symptoms (DRESS), Stevens-Johnson syndrome (SJS), and toxic epidermal necrolysis (TEN). If any of the symptoms of these serious skin reactions (listed in section 4) occur, discontinue mesalazine immediately and seek medical help.
Rarely, mesalazine has been associated with cardiac hypersensitivity reactions (myocarditis and pericarditis).
Very rarely, serious blood disorders have been reported.
If acute intolerance symptoms occur during treatment, such as colicky abdominal pain, acute abdominal pain, fever, severe headache, or rash, treatment must be stopped immediately and the doctor contacted.
Usually, before starting and during treatment, the doctor will order blood and urine tests to monitor liver, kidney, and haematopoietic system function.
Mesalazine may cause a reddish-brown discoloration of urine when it comes into contact with sodium hypochlorite bleach present in toilet water. This is a chemical reaction between mesalazine and bleach and is harmless.
