Warnings and precautions
Consult your doctor before taking Asacol, especially if you:
- suffer from any lung disease, such as asthma.
- have had an allergy to sulfasalazine in the past.
- have ever had heart allergic reactions such as inflammation of the heart muscle or pericardium. If you have had previous suspicions of mesalazine-induced allergic reactions in the heart, then you should not take Asacol. Asacol can be used with caution if you have previously suffered a non-mesalazine-induced heart allergic reaction.
- If you have a stomach or intestinal ulcer, you should take Asacol with caution.
- If you have ever had a severe skin rash or skin peeling, blisters, or sores in the mouth after using mesalazine.

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 a sufficient amount of liquid during treatment with 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.
Severe skin rashes, 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 rashes described in section 4.
