  • What is the most important information I should know about Visicol?

    Visicol can cause serious kidney problems. This often happens within a few days, but sometimes can happen several months after taking Visicol.

    Your risk for having kidney problems can increase if you experience dehydration, slow moving bowels, constipation, severe stomach pain, or bloating. Also, tell your doctor if you have any disease that causes bowel irritation, colitis (inflammation of the colon), kidney disease, or heart failure, as these conditions can increase your risk. Taking diuretics (water pills) (such as furosemide or hydrochlorothiazide) or nonsteroidal anti-inflammatory drugs (NSAIDs) (such as ibuprofen) can also increase your risk for having kidney problems.

    Visicol can cause severe dehydration and changes in your electrolytes (chemicals that are important for the cells in your body to function, such as sodium and potassium). These problems can cause abnormal heartbeats, seizures, kidney problems, or even death. Tell your doctor immediately if you experience vomiting, dizziness, or headaches, or if you urinate less often than normal.
