What is polyethylene glycol 3350 and how does it work?
Polyethylene glycol 3350 is an osmotic laxative that treats occasional constipation (irregularity). It works by holding water in the stool, which softens the stool and increases how often you have a bowel movement. It does not stimulate the bowel, so it usually works gently over 1 to 3 days rather than all at once. It is sold as a tasteless powder you dissolve in a drink. Polyethylene glycol 3350 was first approved as a prescription product in 1999 and switched to over-the-counter status in 2006.
The generic (polyethylene glycol 3350) and the brand MiraLAX contain the same active ingredient, so a generic or store brand works the same way as the brand name.
How to save on polyethylene glycol 3350 with an Rx.com coupon
Polyethylene glycol 3350 is available over the counter, and prices vary from store to store. Because it is also available as a low-cost generic and sold under many store brands, comparing options can save you money. Some pharmacies ring it up cheaper with an Rx.com discount coupon, and in some cases having your doctor write it as a prescription lets you use a coupon price at the pharmacy counter. There is no manufacturer copay savings card for this product.
To find the lowest price, enter your ZIP above to see today's price at pharmacies near you, then show the free Rx.com coupon to the pharmacist. The coupon works for both the brand and generic versions.
How it compares to other laxatives
Polyethylene glycol 3350 is an osmotic laxative, meaning it draws water into the stool. Other laxatives work in different ways, and the best choice depends on your situation and your doctor's advice:
- Lactulose and magnesium citrate are other osmotic-type laxatives that pull water into the bowel.
- Docusate is a stool softener that helps stool absorb water.
- Senna and bisacodyl are stimulant laxatives that prompt the bowel to move.
- Linaclotide is a prescription medicine for chronic constipation and IBS with constipation.
This is general information, not medical advice. Ask your pharmacist or doctor which option is right for you.
Safety, side effects, and when to call a doctor
Do not use polyethylene glycol 3350 if you have a known or suspected bowel obstruction (intestinal blockage) or an allergy to polyethylene glycol. For over-the-counter self-treatment, do not use it for more than 7 days unless your doctor tells you to. Prolonged or excessive use can cause electrolyte imbalance and, rarely, dehydration, acute kidney injury, or metabolic acidosis. Common side effects include bloating, gas, cramping, nausea, and loose or watery stools or diarrhea.
Stop using it and consult a doctor if you have rectal bleeding, severe or worsening abdominal pain, or no bowel movement after use. If you are pregnant or breastfeeding, talk with your clinician before use. There is no boxed warning. This information does not replace advice from your own healthcare provider.
