- There is no evidence to show that any one oral preparation of mesalazine is more effective than another however, the delivery characteristics of oral mesalazine preparations may vary. If it is necessary to switch a patient to a different brand of mesalazine the patient should be advised to report any changes in symptoms.
- Pentasa® tablets may be dispersed in water without losing the M/R effect. They should not be chewed.
- Mesalazine has very little benefit in maintaining remission in Crohn’s disease and therefore is not recommended for use in Crohn’s, except for perhaps Crohn’s colitis.
- Aminosalicylates can cause blood disorders; patients should report any unexplained bleeding, bruising, purpura, sore throat, fever or malaise occurring during therapy. A blood count should be performed and the drug stopped immediately if a blood dyscrasia is suspected.
- Avoid aminosalicylates (mesalazine, olsalazine, sulfasalazine) in patients allergic to aspirin, and those with renal disease.
- Renal function should be monitored before starting an oral aminosalicylate, at 3 months of treatment and then annually during treatment (more frequently in renal impairment).
