USES: This medication is used to treat occasional constipation. It works by holding water in the stool to soften the stool and increases the number of bowel movements. It is known as an osmotic-type laxative.
HOW TO USE: Take by mouth usually once daily, or as directed by your doctor. If you are prescribed the individual packets, mix the powder as directed by your doctor or pharmacist. If you are using the bulk bottle, use the provided cap to measure the prescribed dose. Mix the powder with a full glass (8 ounces or 240 milliliters) of liquid such as water, juice, soda, coffee, or tea. Before drinking the solution, stir the powder well until it completely dissolves. If you have any questions, ask your pharmacist. It may take 2 to 4 days after you have started this medication to have a bowel movement. Do not increase your dose or take it more frequently than prescribed. Also, do not use this medication for more than 2 weeks unless directed by your doctor. Extended use or overuse may result in dependence on laxatives and chronic constipation. Overuse may cause diarrhea, excess loss of body water (dehydration), and mineral imbalance (e.g., low sodium). Inform your doctor if your condition persists or worsens.
SIDE EFFECTS: Nausea, abdominal cramping, or gas may occur. If any of these effects persist or worsen, notify your doctor or pharmacist promptly. Remember that your doctor has prescribed this medication because the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects. Inform your doctor immediately if you have excessive number of bowel movements and persistent diarrhea while using this medication. A very serious allergic reaction to this drug is unlikely, but seek immediate medical attention if it occurs. Symptoms of a serious allergic reaction may include: rash, itching, swelling, severe dizziness, trouble breathing. If you notice other effects not listed above, contact your doctor or pharmacist.
