Polyethylene Glycol 3350 Information

(pol ee eth' i leen) (glye' col)

Polyethylene glycol 3350 is used to treat occasional constipation. Polyethylene glycol 3350 is in a class of medications called osmotic laxatives. It works by causing water to be retained with the stool. This increases the number of bowel movements and softens the stool so it is easier to pass.
Polyethylene glycol 3350 comes as a powder to be mixed with a liquid and taken by mouth. It is usually taken once a day as needed for up to 2 weeks. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take polyethylene glycol 3350 exactly as directed. Polyethylene glycol 3350 may be habit-forming. Do not take a larger dose, take it more often, or take it for a longer period of time than your doctor tells you to. It may take 2 to 4 days for polyethylene glycol 3350 to produce a bowel movement. To use the powder, follow these steps:
  • If you are using polyethylene glycol 3350 from a bottle, use the measuring line on the bottle cap to measure a single dose (about 1 heaping tablespoon). If you are using polyethylene glycol 3350 packets, each packet contains a single dose.
  • Pour the powder into a cup containing 8 ounces (240 milliliters) of water, juice, soda, coffee, or tea.
  • Stir to dissolve the powder.
  • Drink immediately.
    Before taking polyethylene glycol 3350,
  • tell your doctor and pharmacist if you are allergic to polyethylene glycol or any other medications.
  • tell your doctor and pharmacist what prescription and nonprescription medications, vitamins, nutritional supplements, and herbal products you are taking.
  • tell your doctor if you have or have ever had a bowel obstruction (blockage in the intestine) and if you have symptoms of bowel obstruction (upset stomach, vomiting, and stomach pain or bloating).
  • tell your doctor if you are pregnant, plan to become pregnant, or are breast-feeding. If you become pregnant while taking polyethylene glycol 3350, call your doctor.
Eat a well-balanced diet that includes fiber-rich foods, such as unprocessed bran, whole-grain bread, and fresh fruits and vegetables. Drink plenty of fluids and exercise regularly.
This medication is usually taken as needed.

Keep this medication in the container it came in, tightly closed, and out of reach of children. Store it at room temperature and away from excess heat and moisture (not in the bathroom). Unneeded medications should be disposed of in special ways to ensure that pets, children, and other people cannot consume them. However, you should not flush this medication down the toilet. Instead, the best way to dispose of your medication is through a medicine take-back program. Talk to your pharmacist or contact your local garbage/recycling department to learn about take-back programs in your community. See the FDA's Safe Disposal of Medicines website (http://goo.gl/c4Rm4p) for more information if you do not have access to a take-back program. It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location – one that is up and away and out of their sight and reach. http://www.upandaway.org
In case of overdose, call the poison control helpline at 1-800-222-1222. Information is also available online at https://www.poisonhelp.org/help. If the victim has collapsed, had a seizure, has trouble breathing, or can't be awakened, immediately call emergency services at 911.
Keep all appointments with your doctor. Do not let anyone else take your medication. Ask your pharmacist any questions you have about refilling your prescription. It is important for you to keep a written list of all of the prescription and nonprescription (over-the-counter) medicines you are taking, as well as any products such as vitamins, minerals, or other dietary supplements. You should bring this list with you each time you visit a doctor or if you are admitted to a hospital. It is also important information to carry with you in case of emergencies.
