1. What is Asacol and what is it used for
Asacol contains the active substance mesalazine. It is an anti-inflammatory drug used to treat ulcerative colitis. Ulcerative colitis is a disease in which the lining of the large intestine (colon) or the final part of the large intestine (rectum) becomes inflamed (red and swollen). This can cause frequent bowel movements with blood along with abdominal cramps.
Asacol is indicated for the treatment of the acute phase of mild to moderate ulcerative colitis and for the maintenance of remission.
2. What you need to know before you take Asacol
Do not take Asacol if:
- you are allergic to the active substance or any of the other ingredients of this medicine (listed in section 6).
- you are allergic to salicylates (salicylic acid)
- you have severe liver damage
- you have severe kidney damage
Warnings and precautions
Consult your doctor or pharmacist before starting to take Asacol if you have any medical problem or disease, especially if:
- you suffer from any lung disease, such as asthma
- you have ever had kidney or lung failure
- you have had an allergic reaction to sulfasalazine in the past
- you have had a heart allergic reaction, such as inflammation of the heart muscle. If you have had heart allergic reactions induced by mesalazine, then Asacol should not be used. Asacol should be used with caution if you have had a previous heart allergic reaction not caused by mesalazine
- 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 or blisters or ulcers in the mouth after using mesalazine
If you experience severe headache or recurrent headache, vision changes or ringing or buzzing in the ears, contact your doctor immediately.
Severe skin rashes, such as 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 observe any of the symptoms related to these severe skin reactions described in section 4.
Kidney stones may occur with the use of mesalazine. The symptoms include pain in the sides of the abdomen and blood in the urine. Make sure to drink enough 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.
Assessment of your liver, kidneys, and blood
Before and during treatment with Asacol, your doctor may want to assess you from time to time to check that your liver, kidneys, blood, and lungs are in good condition.
Children and adolescents
Do not give this medicine to children or adolescents under 18 years of age, as Asacol has not been tested in this age group.
Other medicines and Asacol
Tell your doctor or pharmacist if you are using, have recently used, or might use any other medicines.
- Medicines to prevent blood clotting (anticoagulants, e.g., warfarin). The effects of these medicines may be increased or decreased, the effects this may have on you are unknown.
- Medicines to reduce the activity of the immune system (e.g., azathioprine or 6-mercaptopurine or thioguanine). Used together with Asacol, these medicines may cause life-threatening infections (see section 4).
- Non-steroidal anti-inflammatory medicines (e.g., medicines containing acetylsalicylic acid, ibuprofen, or diclofenac).
Using Asacol with food and drinks
Consumption of food, drinks, or alcohol does not interfere with the consumption of Asacol.
Pregnancy and breastfeeding
If you are pregnant or breastfeeding, think you may be pregnant, or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine.
Mesalazine is excreted in breast milk in small amounts, so special caution is recommended if Asacol is used during breastfeeding. If the baby develops diarrhea, breastfeeding should be discontinued.

Asacol has no or negligible influence on the ability to drive and use machines. However, if you feel affected, you should not drive or use machines.
Asacol contains sodium
