Polyethylene Glycol 3350 – What It Is and When You Need It

If you’ve ever stared at a bottle of powder in a pharmacy and wondered what it’s for, you’re not alone. Polyethylene glycol 3350, often shortened to PEG 3350, is an over‑the‑counter laxative that works by drawing water into the colon. This softens stool and makes it easier to pass. People use it for everyday constipation, for occasional bloating, or as a bowel‑cleansing prep before a colonoscopy.

Unlike stimulant laxatives that jolt the gut, PEG 3350 is gentle and stays in the intestine until it does its job. That means fewer cramping episodes and a lower chance of the “bounce‑back” constipation you sometimes get after strong pills.

How to Take PEG 3350 Correctly

Getting the dosage right is simple: mix the recommended amount of powder (usually one capful or the scoop that comes with the package) into eight ounces of water, juice, or a clear liquid. Stir until the powder dissolves, then drink it right away. Most brands advise taking it once a day for a few days until you have a bowel movement.

If you’re using PEG 3350 for a colonoscopy prep, the schedule will be more intensive. Your doctor will give you a specific plan – often a larger dose the night before and a smaller dose the morning of the procedure. Follow those instructions exactly; a clean colon is crucial for accurate results.

Do not skip meals or dehydrate while you’re on PEG 3350. Keep a water bottle handy and sip throughout the day. Staying hydrated helps the powder work faster and reduces the chance of feeling too full.

Side Effects, Precautions, and Buying Tips

The most common side effect is mild bloating or gas. Some people notice a brief increase in stomach rumbling. If you experience severe abdominal pain, vomiting, or blood in your stool, stop the product and call a healthcare professional right away.

PEG 3350 is generally safe for most adults, but there are a few groups that should be careful. Patients with kidney disease, severe electrolyte imbalances, or a history of bowel obstruction should talk to a doctor before starting. Pregnant or nursing moms also need medical advice, just to be sure.

When you’re ready to buy, look for products that list “polyethylene glycol 3350” as the active ingredient, not a brand name you can’t recognize. Check the expiration date, and store the powder in a cool, dry place. Many UK online pharmacies, including The Independent Pharmacy, ship PEG 3350 with discreet packaging and clear usage instructions.

To sum it up, polyethylene glycol 3350 is a reliable, gentle way to get things moving when constipation strikes or when you need a clean colon for a test. Use the right dose, stay hydrated, and watch for any unusual symptoms. If you have any doubts, a quick chat with a pharmacist can clear things up and keep you on the right track.
