• If you are allergic to mesalazine or any of the other ingredients of this medication (listed in section 6)
• If you are allergic to salicylates (e. g. aspirin)
• If you have severe kidney problems
• If you have severe liver problems

Talk to your doctor before taking Octasa if you have any medical conditions or illnesses, particularly if you have:

• ever had any problems with your kidneys. This is especially important if you are elderly.
• any lung problems, e. g. asthma.
• suffered an allergy to sulfasalazine in the past.
• ever had allergic reactions of your heart such as inflammation of the heart muscle or heart sac. If you have had previous suspected mesalazine-induced allergic reactions of your heart, then Octasa must not be taken. Octasa can be taken with care if you have had a previous allergic reaction of the heart not caused by mesalazine.
• If you have an ulcer of the stomach or intestine, you may take Octasa with care
• ever developed a severe skin rash or skin peeling, blistering and/or mouth sores after using 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.

If you have an ulcer of the stomach or intestine, you may take Octasa with care.

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

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.

Before and while you are taking Octasa, your doctor may want to monitor you from time to time, to check that your liver, kidneys, blood and lungs are all right.

There have been a few reports of intact tablets in the stool. What appear to be intact tablets may sometimes be the remains of the tablet coating. If you often observe tablets or tablet shells in the stool, you should consult your doctor.
