Mesalamine suppositories reach up to the first 15 to 20 cm (average disease boundary) of the rectum4

CANASA® is available by prescription only.
CANASA® 1000 mg Suppositories are indicated for the treatment of active ulcerative proctitis.

As with other mesalamine containing products, less common but possibly serious side effects such as acute intolerance syndrome, pericarditis and pancolitis may occur.
Patients on CANASA® 1000 mg, especially those on concurrent oral products which contain or release mesalamine and those with pre-existing renal disease, should be carefully monitored with urinalysis, BUN and creatinine testing.
Caution should be exercised when CANASA® suppositories are initially used in patients known to be allergic to sulfasalazine.
CANASA® was generally well tolerated in clinical studies. The most common side effects of CANASA® are dizziness (3%), rectal pain (1.8%), fever (1.2%), rash (1.2%), acne (1.2%), and colitis (1.2%).
