Polyethylene glycol 3350 comes as a powder that needs to be mixed with a liquid and taken orally. It is usually taken once a day, as needed, for up to two weeks. Follow the directions on the prescription label carefully and ask your doctor or pharmacist to explain any part that you do not understand. Take polyethylene glycol 3350 exactly as directed.
Do not take a larger dose, take it more often, or take it for a longer period than your doctor tells you to, as it may be habit-forming. It may take up to four days for polyethylene glycol 3350 to produce a bowel movement.
To use the powder, take the following steps:
- If using polyethylene glycol 3350 from a bottle, use the measuring line on the bottle cap to measure a single dose, which is about one heaping tablespoon. If using polyethylene glycol 3350 packets, each packet contains a single dose.
- Pour the powder into a cup containing 8 ounces or 240 milliliters of water, juice, soda, coffee, or tea.
- Stir to dissolve the powder.
- Drink immediately.
