No, changes in weight aren’t a known side effect of Apriso. But UC can cause weight loss as a symptom. So weight gain or weight loss could be a sign that Apriso isn’t working well to maintain your UC remission (a period of time without active symptoms).
If you notice that your weight is changing while taking Apriso, talk with your doctor or pharmacist. They can help determine the cause and recommend ways for you to maintain a moderate weight. And be sure to talk with your doctor if you think your UC symptoms may be returning.
