Balsalazide disodium, also known by the brand name Colazal, is an aminosalicylate. It's a first-choice treatment option for treating mild-to-moderate ulcerative colitis (UC) in people age 5 years and older. Balsalazide (Colazal) is available as 750 mg capsules. The typical dosage for adults is 3 capsules by mouth three times per day. Children can take either 1 or 3 capsules by mouth three times per day. Side effects include stomach pain and diarrhea.
Balsalazide (Colazal) is an aminosalicylate. Once swallowed, the medication reaches the colon. It blocks the body from making inflammatory proteins and chemicals in the gut. This is thought to lessen inflammation in the gut.

No, balsalazide (Colazal) isn't a steroid. It's an aminosalicylate. Steroids and aminosalicylates both are types of medications that help treat UC. But they work differently to lessen inflammation in the gut. In general, treatment guidelines for mild UC typically prefer trying aminosalicylates first because steroids are known for their short- and long-term side effects. Speak with your prescriber about your treatment plan.
Balsalazide (Colazal) isn't the same as mesalamine. But the two different medications are related. They're both aminosalicylates that are approved for treating mild-to-moderate ulcerative colitis (UC). Of note, after you swallow balsalazide (Colazal), the body turns balsalazide into mesalamine. Balsalazide (Colazal) is only available as a capsule that's taken three times a day. But there are many forms of mesalamine, including pills, enemas, and suppositories. And each form of mesalamine can have different instructions on how to take it. Studies suggest that balsalazide (Colazal) might work better and faster than mesalamine pills. Compare between balsalazide (Colazal) and mesalamine, and talk to your gastroenterologist if you have more questions about the two medications.
Hair loss wasn't a side effect balsalazide (Colazal) that people who took the medication reported having during clinical trials. But some people reported hair loss after the medication became available on the market. It's not completely clear whether balsalazide (Colazal) directly caused the hair loss or whether it was from something else. Contact your prescriber if you notice unusual hair loss while you're taking balsalazide (Colazal). They can examine what's causing this hair loss.
Weight gain wasn't a typical side effect reported in people who took balsalazide (Colazal) during clinical trials. Keep in mind that severe gut-related symptoms of UC can lead to low appetite and weight loss. So it's possible that you might slowly get your appetite back and gain a little weight if balsalazide (Colazal) is working to treat your UC. Discuss with your care team about ways to incorporate balanced, nutritious meals and regular exercise into your daily routine to manage your weight.
It's recommended for adults and children age 5 and older to take balsalazide (Colazal) for up to 8 weeks. Some adults needed to take the medication for up to 12 weeks during clinical trials. Discuss with your prescriber about how long you should take balsalazide (Colazal) based on your condition and how the medication is working for you.
Because balsalazide (Colazal) gets broken down in the body into many chemicals, it's not completely clear how long the medication stays in your system. We do know that balsalazide gets broken down in the body into mesalamine, which is the main component of the medication that works to lessen inflammation in the gut. Mesalamine can stay in your body for about 5 days. This time frame is estimated based on the half-life of mesalamine. Even though it might stay in the body for several days, it's recommended to take balsalazide (Colazal) three times every day. This helps keep the levels of the medication in your body high enough so it can work well.
No, balsalazide (Colazal) doesn't contain any sulfa. This means that balsalazide (Colazal) is safe for people who have a sulfa allergy.
Let a member of your healthcare team know if you're breastfeeding. They can discuss the risks and benefits of taking balsalazide (Colazal) with you. It's considered generally safe to breastfeed while you're taking this medication. But be aware that your baby might get diarrhea. Ask a healthcare professional if you have more questions about breastfeeding while you're taking balsalazide (Colazal).
Balsalazide (Colazal) can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.
Some people who take balsalazide (Colazal) have had kidney damage. Your risk for kidney damage is higher if you have kidney problems or if you take medications that can harm the kidneys, like nonsteroidal anti-inflammatory drugs (NSAIDs) and diuretics (water pills).
You might need blood work or urine tests done every so often during treatment so your prescriber can check your kidney function. Tell your care team if you have any signs or symptoms of kidney problems while you're taking balsalazide (Colazal), including changes in your need to urinate, tiredness, low appetite, and muscle cramps.
Some people who take balsalazide (Colazal) can get kidney stones. Make sure to stay hydrated each day while you're taking this medication to prevent kidney stones. Let your prescriber know if you have trouble urinating, notice a change in how much you urinate, have blood in the urine, or feel back or side pain. These can be signs of a kidney stone.
Although rare, some people who take balsalazide (Colazal) can have a reaction to the medication called acute intolerance syndrome. It typically happens 1 to 3 weeks after starting balsalazide (Colazal). And it usually goes away within a few days after stopping the medication or after starting corticosteroid treatment.
Symptoms of acute intolerance syndrome can be hard to tell apart from a flare-up of UC. Let your care team know if you have symptoms like stomach cramping or pain, bloody diarrhea, fever, headache, and rash. You might need to stop taking balsalazide (Colazal) to help these symptoms go away.
Severe allergic reactions to balsalazide (Colazal) are possible. They can include life-threatening reactions like facial swelling, shock, and anaphylaxis (e.g., closing of the throat). Get emergency medical help right away if you notice hives, rash, swelling of the lips or tongue, or difficulty breathing after you take balsalazide (Colazal).
Balsalazide (Colazal) can cause rare but serious skin reactions. These skin reactions can include Stevens-Johnson syndrome (SJS) or toxic epidermal necrolysis (TEN), and drug reaction with eosinophilia and systemic symptoms (DRESS) syndrome.
Stop taking balsalazide (Colazal) and get medical attention right away at the first sign of any unusual changes in your skin, like rash, blisters, peeling skin, or skin reddening. These skin reactions can sometimes happen with fever, sore throat, fatigue, and swollen lymph nodes, so watch out for these symptoms as well.
Although rare, some people with liver problems had liver failure after they took mesalamine, a similar medication to balsalazide (Colazal). Let your prescriber know if you have a history of liver problems before you start taking balsalazide (Colazal). They can weigh the risks and benefits of treatment.
Get medical help as soon as possible if you notice severe nausea, vomiting, right-sided stomach pain, fatigue, low or no appetite, or yellowing of the skin or eyes while you're taking balsalazide (Colazal). These can be signs of liver damage.
People with skin conditions like eczema who take balsalazide (Colazal) are at higher risk that their skin gets more sensitive to the sun. This means that they can get sunburns more easily than usual.
To lower your risk for sunburn, wear sunscreen and long-sleeved clothing to protect your skin when you're outside, even during the winter and on overcast days. Also try to find shade as much as possible.
People who have or are at risk of a bowel obstruction should avoid taking balsalazide (Colazal). Gut blockages can make it take longer for the medication to reach your colon and help treat your UC. Let your prescriber know right away if you notice symptoms of a bowel obstruction, like severe stomach cramping, severe stomach pain, vomiting, constipation, or a hard or swollen belly.
