1. What is Pentasa and what is it used for
Mesalazine, the active substance of Pentasa, acts locally as an anti-inflammatory agent on the diseased wall of the small and large intestine. Mesalazine is released from the tablets in a continuous manner throughout the entire length of the intestine, regardless of the pH value. Pentasa is used to treat mild and moderate ulcerative colitis and Crohn's disease.
2. Important information before taking Pentasa
BEFORE TAKING MESALAZINE, INFORM YOUR DOCTOR:
- If you have ever experienced a severe skin rash or skin peeling after taking mesalazine, or blisters or ulcers in the mouth.
When not to take Pentasa
if you are allergic to mesalazine or any of the other ingredients of this medicine (listed in section 6), if you are allergic to salicylates, such as aspirin, if you have severe liver or kidney problems, if you have stomach or duodenal ulcers, if you have haemorrhagic diathesis.
Warnings and precautions
Before taking Pentasa, discuss it with your doctor. Be cautious: if you are allergic to sulfasalazine, if you have liver or kidney problems, if you are being treated with medicines that may affect kidney function, if you are being treated with azathioprine (an immunosuppressant), 6-mercaptopurine (an anticancer and immunosuppressant), or tioguanine (an anticancer), if you have lung problems, especially asthma, if you experience severe or recurring headache, vision disturbances, or ringing or buzzing in the ears, you should contact your doctor immediately. Taking mesalazine may lead to the formation of kidney stones. Symptoms may include pain in the sides of the abdomen and blood in the urine. During treatment with mesalazine, you should drink an adequate amount of fluids. Serious skin reactions, including drug reaction with eosinophilia and systemic symptoms (DRESS), Stevens-Johnson syndrome (SJS), and toxic epidermal necrolysis (TEN), have been reported with mesalazine treatment. You should stop taking mesalazine and seek medical attention immediately if you experience any of the symptoms of these serious skin reactions, listed in section 4. Rarely, mesalazine has been associated with myocarditis (inflammation of the heart muscle) and pericarditis (inflammation of the lining surrounding the heart). Very rarely, serious blood disorders have been reported. If you experience acute symptoms of intolerance, such as crampy abdominal pain, acute abdominal pain, fever, severe headache, or rash, you should stop treatment and contact your doctor immediately. Usually, before and during treatment, your doctor will order blood and urine tests to assess liver, kidney, or blood function. Mesalazine may cause a reddish-brown discoloration of urine after contact with sodium hypochlorite bleach in toilet water. This is a harmless chemical reaction between mesalazine and bleach.
