1. What Pentasa tablets are and what they are used for
Pentasa tablets are indicated to help you stay free from new flare-ups of ulcerative colitis.
Ulcerative colitis is an inflammatory bowel disease in which the lining of the intestine is inflamed and develops many small breaks in its surface (ulcers) that can bleed.
Pentasa contains the active ingredient mesalazine, which belongs to a group of medicines called intestinal anti-inflammatory agents that help reduce inflammation and painful symptoms.
2. What you need to know before you take Pentasa tablets
Do not take Pentasa tablets:
- if you are allergic to the active ingredient or any of the other ingredients of this medicine (listed in section 6).
- if you are allergic to salicylates, for example aspirin.
- if you have severe kidney and/or liver problems.
Warnings and precautions
Talk to your doctor or pharmacist before taking this medicine:
- if you are allergic to sulfasalazine (risk of salicylate allergy)
- if you currently have or have had liver or kidney function impairment
- if you have a disease that may make you prone to bleeding
- if you are taking treatment that may affect kidney function, for example non-steroidal anti-inflammatory drugs (NSAIDs) such as aspirin
- if you have respiratory problems, particularly asthma
- treatment should be discontinued immediately in case of cramps, abdominal pain, fever, severe headache, and rash.
- 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.
- If you have ever suffered from a severe skin rash, skin peeling, blisters, or sores in the mouth after using 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.
Be careful with mesalazine:
Severe skin reactions, 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 notice any of the symptoms related to these severe skin reactions described in section 4.
If you experience severe or recurrent headache, vision changes, or ringing or buzzing in the ears, contact your doctor immediately.
While you are taking this medicine, your doctor will normally perform blood and urine tests to monitor your kidney function, especially at the start of treatment.
Use in people over 65 years:
It should be used with caution in people over 65 years and only in patients with normal kidney function.
