For constipation, the usual dose for adults and children over 12 years of age is 1 to 2 tablets (5 mg to 10 mg) taken by mouth, or 1 adult suppository (10 mg) inserted rectally. For children 6 to 12 years of age, the usual dose is 1 tablet (5 mg) taken by mouth or 1 pediatric suppository (5 mg) inserted rectally.
Before a medical test or surgery, the usual dose for adults is 2 to 4 tablets (10 mg to 20 mg) by mouth the night before the procedure, followed by 1 suppository inserted rectally the morning of the procedure. For children 6 years of age and older, the usual dose is 1 tablet (5 mg) taken by mouth at bedtime and 1 pediatric suppository (5 mg) inserted rectally the following morning.
Take the tablets at night to produce a bowel movement the following morning. Do not take the tablets with milk or antacids as this may dissolve the coating on the tablet. Swallow the tablets whole with liquids. Do not crush or chew the tablets.
To use the suppositories, unwrap and insert high into the rectum with the pointed end first. Then, push the flat end of the suppository sideways so that part of it touches the wall of the rectum. Keep the suppository in the rectum for as long as possible. If inserting the suppository is difficult because you have had anal fissures or hemorrhoids, coat the end of the suppository with a lubricant such as petroleum jelly before inserting. The suppositories will start to work within 15 minutes to 1 hour.
