Do not take this medicine together with other laxatives or enemas containing sodium phosphate. Doing so may lead to serious unwanted effects.
This medicine may cause serious kidney problems. These are more likely to occur if you are over 55 years of age, dehydrated, have low blood volume, and are taking medicines that could be hard on your kidneys (eg, diuretics or water pills, certain blood pressure medicines, NSAID pain or arthritis medicine). Check with your doctor right away if you have bloody urine, a decrease in the amount or frequency of urine, lower back or side pain, trouble breathing, weight gain, or swelling of the face, fingers, and lower legs.
Taking more than one dose of over-the-counter (OTC) sodium phosphate medicine in 24 hours may cause serious kidney and heart problems. Check with your doctor if you have the following symptoms: confusion, decreased urination, dizziness, dry mouth, fainting, increase in heart rate, rapid breathing, or unusual tiredness or weakness.
Contact your doctor right away if you have any changes to your heart rhythm. You might feel dizzy or faint, or you might have a fast, pounding, or uneven heartbeat. Make sure your doctor knows if you had a heart rhythm problem, such as QT prolongation.
This medicine may cause serious allergic reactions, including anaphylaxis and angioedema, which can be life-threatening and require immediate medical attention. Tell your doctor right away if you have a rash, itching, hoarseness, trouble breathing, trouble swallowing, or any swelling of your hands, face, or mouth after using this medicine.
Call your doctor right away if you have any unusual symptoms that concern you, such as bloating, abdominal or stomach pain, seizures, nausea, vomiting, or headache.
Do not take other medicines unless they have been discussed with your doctor. This includes prescription or nonprescription (over-the-counter [OTC]) medicines and herbal or vitamin supplements.
