In case of appearance of any allergic manifestation (e.g., skin rash, itching) or cramps, abdominal pain, severe headache, and fever during the course of treatment, do not use Claversal suppositories anymore and inform your doctor immediately.
Before and during treatment, your doctor may want to perform regular blood and urine tests to check the functioning of your liver, kidneys, blood, and lungs.
Kidney stones may occur with the use of mesalazine. Symptoms include pain in the sides of the abdomen and blood in the urine. Make sure to drink enough liquid during treatment with mesalazine.
Severe skin reactions, such as drug reaction with eosinophilia and systemic symptoms (DRESS), Stevens-Johnson syndrome (SSJ), and toxic epidermal necrolysis (TEN), have been observed with mesalazine treatment. Stop taking mesalazine and seek medical attention immediately if you observe any of the symptoms related to these severe skin reactions described in section 4.
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.
