The risk is also increased if you have low blood levels of electrolytes such as calcium, magnesium, potassium or sodium, which can occur with bowel cleansing preparations or excessive use of medications that have a laxative effect. You should use polyethylene glycol 3350 with electrolytes exactly as prescribed by your doctor, and drink plenty of clear liquids before, during, and after the cleansing process to avoid becoming dehydrated. Your doctor may be able to recommend specific fluids you can drink before starting polyethylene glycol 3350 with electrolytes to help maintain your electrolyte levels. Contact your doctor if you experience signs and symptoms of low electrolyte levels such as weakness, tiredness, drowsiness, dizziness, confusion, tingling, numbness, muscle pain, cramps, nausea, or vomiting. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.
