Indications  

Colazal is a prescribed medication for treating mild to moderately active ulcerative colitis in adults and children aged 5 and above. This condition is characterized by inflammation and sores in the lining of the colon and rectum. 

As an aminosalicylate drug, Colazal works to reduce bowel inflammation, diarrhea, rectal bleeding, and stomach pain associated with the condition. 

Uses and Dosage 

Before taking Colazal and with each prescription refill, thoroughly review its medication guide and patient information leaflet. Ask your doctor or pharmacist if you have any questions or concerns. 

Colazal dosage is determined based on the patient’s age, medical condition, and response to the treatment. 

Typically, this medication is taken three times a day as prescribed by the doctor, without regard to food intake.  

Colazal capsules can be taken whole or opened and mixed with applesauce for easier swallowing. The mixture should be consumed immediately and not stored for future use. If necessary, the mixture can be chewed. 

For the best results, take Colazal regularly at the same time(s) each day. Avoid taking more or less than the prescribed dosage or more frequently than your doctor instructed. 

Inform your doctor if your condition does not improve or worsens.

• Salicylates (e.g., aspirin or salsalate)

Some medicines may interact with Colazal, including dichlorphenamide. To minimize such drug interactions, inform your doctor and pharmacist about all your medications, including prescription and over-the-counter drugs, other dietary supplements, and herbal products. 

Balsalazide, the active ingredient of Colazal, closely resembles mesalamine. Refrain from taking oral mesalamine drugs during Colazal treatment. 

Colazal tablets contain sodium. If you are following a low-salt diet, consult your doctor before using this medication. 

Inform lab personnel and all physicians that you take Colazal, as it may disrupt specific lab tests (such as urine normetanephrine levels) and yield inaccurate results. 

Colazal can increase sensitivity to sunlight, particularly if you have skin conditions like atopic dermatitis or eczema. Limit sun exposure, avoid tanning booths and sunlamps, and take precautions such as using sunscreen and wearing protective clothing when outdoors. In case of sunburn or skin blisters/redness, promptly inform your doctor. 

During pregnancy, the use of Colazal should be limited to situations where it is clearly necessary. Discuss thoroughly with your doctor the risks and benefits of using the medication. 

The excretion of balsalazide in human milk is unknown. Consult with your doctor before breastfeeding while taking this medication.
