Constipation and gas are known gastrointestinal side effects of Ursodeoxycholic acid (Golbi 300), and since your symptoms clearly started after beginning this medicine while Thyronorm has caused no issues since April, Golbi 300 is almost certainly the cause. This is a reported but manageable side effect of the medication. The good news is that this does not mean you need to stop the medicine â it can often be managed by adjusting when you take the dose.
Next Steps
Mention this side effect to your prescribing doctor â they may suggest taking it with meals to reduce GI discomfort or make a dose adjustment. In the meantime, increase water intake and include more fiber-rich foods like fruits and vegetables. Do not stop the medicine on your own.
