Miralax Dosing: Simple Guide for Safe Use

If you’ve tried over‑the‑counter laxatives and still feel backed up, Miralax (polyethylene glycol 3350) might be your next step. It works by holding water in the stool so it passes more easily. The key is getting the dose right – too little won’t help, too much can cause cramping.

Adult Dosage Basics

Most adults start with 17 grams of powder mixed into a glass of water, juice, or tea once a day. That’s about one rounded‑off scoop from the package. You’ll usually see results in two to three days, but give it up to a week before deciding if it works for you.

If you’re not seeing any change after a week, increase the dose by 8 grams (half a scoop). Keep the total under 34 grams per day unless your doctor says otherwise. Never double‑dose in one sitting; spread any extra amount across the same day.

Kids & Special Situations

For children aged 1‑17, the typical dose is 0.7 grams per kilogram of body weight once daily, mixed into a drink they like. Most pediatric bottles already have measuring marks to make this easier. Always check with a pediatrician before starting.

If you’re pregnant, nursing, or have kidney disease, talk to your doctor first. Miralax is generally safe, but certain health issues can change how much fluid your body needs to handle the extra water in the stool.

When adjusting doses, remember to stay hydrated. Drinking an extra glass of water each day helps the powder work without causing dehydration or electrolyte imbalance.

Common side effects include mild bloating, gas, or a slightly loose stool. If you get severe cramping, vomiting, or blood in your stool, stop taking Miralax and call a healthcare professional right away.

Never use Miralax for longer than two weeks without medical advice. Prolonged use can mask underlying problems like IBS or bowel obstruction that need proper treatment.

Quick FAQ:
• Can I take it with other meds? Yes, but separate timing by at least 2 hours if possible.
• Do I need to mix it right before drinking? No, you can stir it in and let it sit for a few minutes – the powder dissolves quickly.
• What if I forget a dose? Just take it as soon as you remember, but don’t double up.

Bottom line: start with 17 grams once daily, watch your body’s response, and adjust slowly. If anything feels off, reach out to a pharmacist or doctor. With the right amount, Miralax can turn a stubborn constipation problem into a thing of the past.
