Polyethylene Glycol 3350 – What It Is, How to Use & Where to Buy

If you’ve ever searched for a gentle laxative or a bowel‑prep powder, you probably saw the name Polyethylene Glycol 3350, often shortened to PEG 3350. It’s an over‑the‑counter product that pulls water into your intestines, making stool softer and easier to pass. People use it for occasional constipation, before colonoscopies, or when a doctor needs a clear gut for certain tests.

How Polyethylene Glycol 3350 Works

PEG 3350 is a big molecule that isn’t absorbed into the bloodstream. When you mix the powder with water, it stays in your gut and draws fluid from surrounding tissues. The extra liquid softens stool and speeds up movement through the colon. Because it doesn’t act like a stimulant laxative, you usually feel less cramping or urgency.

Typical doses for constipation are one to two packets (about 17‑34 grams) mixed with an 8‑ounce glass of water once a day. For bowel prep before a colonoscopy, the schedule is more intense – often four packets split into two drinks the night before and two the morning of the procedure. Always follow your doctor’s instructions for the prep version.

Start with the lowest dose that works. If you’re new to PEG 3350, try one packet a day and see how your body reacts. Drink plenty of fluids – at least eight glasses a day – because the powder needs water to work properly.

Common side effects are mild: bloating, gas, or an odd taste in the mouth. If you notice severe stomach pain, vomiting, or no bowel movement after three days, stop using it and call a pharmacist or doctor.

When you shop online, look for reputable pharmacies that require a prescription if the product is sold as a medical‑grade prep. Check customer reviews, verify the site’s contact info, and make sure the price matches what you see in local stores. Avoid sellers with no return policy or who ask for payment via unconventional methods.

Store the powder in a cool, dry place and keep the lid tightly closed. Once opened, use it within the time frame printed on the label – usually six months. If the powder clumps or smells off, discard it; it’s safer to get a fresh batch.

In short, Polyethylene Glycol 3350 is a reliable option for gentle constipation relief and thorough bowel cleansing before procedures. By starting with a low dose, staying hydrated, and buying from trusted sources, you can use it safely without hassle. Have more questions? Talk to your pharmacist – they can help you pick the right brand and dosage for your needs.
