Can the treatment for ulcerative colitis cause white mucus in the stools?

Hello doctor,

My daughter is your old patient. Just to recall, she had ulcerative colitis. She was taking tablet 6-MP 25 mg every other day along with folic acid. After the colonoscopy, you suggested 25 mg tablet 6-MP each day with 2 gm Pentasa and 5 mg folic Acid. We did a couple of blood tests after a few months. The other doctor felt her liver markers were elevated and reduced the dose of the 6-MP tablet. We were not sure how to contact you, So we followed her. After that, we did one more blood test. There was no increase in WBC or RBC. But now, nearly after a month and a half, she is taking 25 mg every other day, and we are seeing white mucus in her stools on and off. She has no belly pain or other symptoms. Frequency is mostly one time a day, and for the last couple of days, it has been twice a day with formed stool. We will be doing one more blood test tomorrow. I am uploading the first two blood test reports now. I will send the next one when it is available. Her current medication is tablet 6-MP 25 mg every other day, Rowasa 2 gm per day, and folic acid 5 mg per day. In the last six months, we have done three calprotectin stool tests. The values were 363, 70 (after four months), and 33 (after two months), respectively. Please advice. Thank you.

Thanks a lot, doctor,

I am attaching her latest blood reports. We will soon take a calprotectin stool test and will forward the reports for the same.

Thanks.
