COLAZAL

Colazal is used to treat the signs and symptoms of mild to moderately active ulcerative colitis. The safety and efficacy of Colazal are not known after 12 weeks.

You should not take Colazal if you are allergic to medicines containing:

• salicylates, such as aspirin
• mesalamine (Rowasa®, Asacol®, or Pentasa®)

Some people experience a worsening of their colitis symptoms possibly related to the use of Colazal.

Tell your doctor or health care provider if you have kidney disease or a history of kidney problems. Patients taking products that contain the same active ingredient as Colazal have sometimes had kidney problems.

Tell your health care provider if you are trying to become pregnant, are already pregnant, or are breast-feeding.

Tell your health care provider if you have pyloric stenosis, a narrowing of the muscle that controls the emptying of the stomach.

Because certain other medications such as antibiotics may interact with Colazal, review all medications that you are taking with your health care provider, including those that you take without a prescription.

Common side effects include:
