Yes, bowel changes like urgency can occasionally be a side effect of your cholesterol medication, rosuvastatin. Eating can sometimes trigger an overactive digestive reflex, leading to this sudden urgency. However, this could also be related to dietary factors or other causes. To help manage this, try eating smaller, more frequent meals and limit spicy or greasy foods. Please do not stop taking your medication abruptly. I highly recommend discussing this symptom with your doctor so they can evaluate the cause, rule out other issues, and safely adjust your treatment plan if necessary.
