What special precautions should I follow?

• Renal impairment, including minimal change disease, acute and chronic interstitial nephritis, and renal failure, has been reported in patients given products such as Colazal that release mesalamine into the gastrointestinal tract. Assess renal function at the beginning of treatment and periodically during treatment. Evaluate the risks and benefits in patients with known renal impairment or taking nephrotoxic drugs; monitor renal function. Discontinue if renal function deteriorates.
• Balsalazide is converted to mesalamine, which has been associated with an acute intolerance syndrome that may be difficult to distinguish from an exacerbation of ulcerative colitis. Symptoms may be difficult to distinguish from an exacerbation of ulcerative colitis; monitor for worsening symptoms; discontinue treatment if acute intolerance syndrome is suspected.
• Some patients have experienced a hypersensitivity reaction to sulfasalazine may have a similar reaction to Colazal or to other compounds that contain or are converted to mesalamine. Evaluate patients immediately and discontinue if a hypersensitivity reaction is suspected.
• There have been reports of hepatic failure in patients with pre-existing liver disease who have been administered mesalamine. Evaluate the risks and benefits in patients with known liver impairment.
• Severe cutaneous adverse reactions, including Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN), drug reaction with eosinophilia and systemic symptoms (DRESS), and acute generalized exanthematous pustulosis (AGEP) have been reported with the use of mesalamine, the active moiety of Colazal. Discontinue at the first signs or symptoms of severe cutaneous adverse reactions or other signs of hypersensitivity and consider further evaluation.
• Pyloric stenosis or other organic or functional obstruction in the upper gastrointestinal tract may cause prolonged gastric retention of Colazal. Avoid in patients with pyloric stenosis or other organic or functional obstruction.
• Patients with pre-existing skin conditions such as atopic dermatitis and atopic eczema have reported more severe photosensitivity reactions. Advise patients with pre-existing skin conditions to avoid sun exposure, wear protective clothing, and use a broad-spectrum sunscreen when outdoors.
• Cases of nephrolithiasis have been reported with the use of mesalamine, the active moiety of Colazal, including stones with 100% mesalamine content. Stones containing mesalamine, the active moiety in Colazal, are undetectable by standard radiography or computed tomography (CT). Ensure adequate fluid intake during treatment with Colazal.
• Use of mesalamine may lead to spuriously elevated test results when measuring urinary normetanephrine by liquid chromatography with electrochemical detection.
• Plan to avoid unnecessary or prolonged exposure to the sunlight and to wear protective clothing, sunglasses, and sunscreen. Balsalazide may make your skin sensitive to sunlight.

What to do in case of emergency/overdose?

Symptoms of overdosage may include:

• nausea, vomiting and abdominal pain, tachypnea, hyperpnea, tinnitus, and neurologic symptoms (headache, dizziness, confusion, seizures)

Management of overdosage:

• There is no specific antidote for balsalazide overdose; however, conventional therapy for salicylate toxicity may be beneficial in the event of acute overdosage and may include gastrointestinal tract decontamination to prevent further absorption.
• Proper medical care should be sought immediately with appropriate supportive care, including the possible use of emesis, cathartics, and activated charcoal to prevent further absorption.
• Correct fluid and electrolyte imbalance by the administration of appropriate intravenous therapy and maintain adequate renal function.

Can this medicine be used in pregnancy?

• The use of mesalamine, the active moiety of Colazal, during pregnancy have not reliably informed an association with mesalamine and major birth defects, miscarriage, or adverse maternal or fetal outcomes.
