About MiraLax Laxative (30 doses) — Complete Product Guide

MiraLax contains polyethylene glycol 3350 (PEG 3350), a gentle osmotic laxative that relieves constipation without stimulants, cramping, or sudden urgency. Unlike harsh stimulant laxatives, MiraLax works with the natural water in your body to hydrate, soften, and ease stool for comfortable, predictable relief. It is the #1 doctor-recommended OTC laxative brand in the United States.

What Conditions Does MiraLax Laxative Treat?

MiraLax Laxative is indicated for the relief of occasional constipation in adults and children 17+, hard or infrequent stools, relief of constipation associated with medication side effects, IBS-related constipation (under medical supervision), and bowel prep support. It is approved for OTC use and does not require a prescription for standard adult doses.

How Does MiraLax Laxative Work?

Polyethylene glycol 3350 is an osmotic agent — it attracts and retains water molecules in the colon. This increases the water content of the stool, softening it and adding bulk. The increased moisture stimulates natural bowel contractions without artificial chemicals or stimulants. Results are predictable and gradual, usually occurring within 1–3 days of the first dose, without sudden urgency or cramping.

Dosage and Usage Instructions

Adults and children 17 and over: Dissolve 1 packet (17g) in 4–8 ounces of any liquid (water, juice, coffee, tea) once daily. Stir and drink until dissolved. Use for up to 7 days unless otherwise directed by a doctor. For long-term use, consult your healthcare provider. Do not exceed 1 dose per day. The 30-pack provides a 30-day supply.

Who Can Use MiraLax Laxative?

MiraLax is for adults and children 17 and older. Not for children under 17 without medical supervision. Consult your doctor before use if you have kidney disease, as PEG laxatives may affect electrolyte balance. Not recommended for use beyond 7 days without medical guidance. Safe during pregnancy for short-term use — always confirm with your OB/GYN.

Possible Side Effects

MiraLax is very well-tolerated. The most common side effects are mild bloating, gas, and nausea — especially when first starting use. These typically improve after the first few days. Diarrhea may occur if too much is taken. Allergic reactions are rare but possible. If you experience severe stomach pain, stop use and seek medical advice.

Frequently Asked Questions — MiraLax (PEG 3350)

How long does MiraLax take to work?

MiraLax typically produces a bowel movement within 1–3 days of starting treatment. It is an osmotic laxative that works by drawing water into the colon to soften stool — it is gentler than stimulant laxatives and does not cause sudden urgency. Source: MedlinePlus: Polyethylene Glycol.

Can I take MiraLax every day?

OTC MiraLax (PEG 3350) is approved for short-term use (7 days). For chronic constipation requiring longer treatment, use only under a doctor's guidance. The FDA has not approved PEG 3350 for long-term daily use without medical supervision.

How do I take MiraLax properly?

Mix the capful (17g) of MiraLax powder in 8oz (240ml) of water, juice, or coffee — it dissolves completely and is tasteless. Take once daily or as directed. Increase fluid intake throughout the day for best results.

Is MiraLax safe for elderly patients?

MiraLax (polyethylene glycol 3350) is generally considered safe for elderly patients and is commonly recommended by gastroenterologists for older adults. Unlike stimulant laxatives, it does not cause cramping or dependency. Always consult a doctor for regular use in elderly patients.

How does MiraLax compare to stimulant laxatives like senna or bisacodyl?

MiraLax is an osmotic laxative that gently draws water into the bowel — no cramping, no urgency. Stimulant laxatives (senna, bisacodyl) work faster (6–12 hours) but cause cramping and can lead to dependency with overuse. For most cases of constipation, MiraLax is the gentler, preferred choice.
