How should I take Citrucel?
Citrucel is usually taken 1 to 3 times per day. Use exactly as directed on the label, or as prescribed by your doctor. Do not use in larger or smaller amounts or for longer than recommended. Overuse of a laxative may cause damage to the nerves, muscles, or tissues in your intestines.
Citrucel is a powder medicine that must be mixed with a full glass (8 ounces) of cold water or other liquid. Drink all of the mixture, and then drink one more glass of water.
Taking Citrucel without enough liquid may cause the powder to swell in your throat and cause choking, especially in older adults.
Seek emergency medical attention if you have chest pain, vomiting, trouble swallowing, or trouble breathing after taking this medicine.
You should have a bowel movement within 12 hours to 3 days.
Call your doctor if your symptoms do not improve after 3 days of treatment.
Store at room temperature away from moisture and heat.
What happens if I miss a dose?
Since Citrucel is used when needed, you may not be on a dosing schedule. If you are on a schedule, use the missed dose as soon as you remember. Skip the missed dose if it is almost time for your next scheduled dose. Do not use extra medicine to make up the missed dose.
