What is Phillips' Milk of Magnesia?
Phillips' Milk of Magnesia Liquid is a traditional, highly trusted over-the-counter medicine renowned for its dual-action capabilities. Featuring a pleasant, cooling mint flavour, this 200ml liquid provides rapid, soothing relief for upset stomachs, heartburn, and trapped wind, while also doubling as a gentle, effective treatment for occasional constipation.
How does the dual-action formula work?
This medication relies on a single, powerful active ingredient—Magnesium Hydroxide (415 mg per 5 ml)—which works in two completely different ways depending on the dosage you take:
| Treatment Use | How It Works in the Body |
|---|---|
| As an Antacid (For Indigestion) | In smaller doses, it acts as an antacid. It rapidly neutralises excess stomach acid on contact, soothing the burning sensation of heartburn and relieving trapped wind and general stomach discomfort[1]. |
| As a Laxative (For Constipation) | In larger doses, it acts as an osmotic laxative. It naturally draws water into the bowel, which softens hard stools and gently stimulates the intestinal muscles to encourage a predictable bowel movement[3]. |
How to take Phillips' Milk of Magnesia
You must shake the bottle vigorously before each use to ensure the liquid is properly mixed. You can use the included dosing cup to measure the exact amount required. If you prefer, you can take the liquid with a glass of water or milk to help wash it down. Because the dosage changes drastically depending on what you are treating, you must follow the instructions below carefully:
Dosage for Indigestion and Heartburn
Do not use this medicine as an antacid for more than 14 days without consulting a doctor. Drink plenty of fluid during the course of your treatment.
| Age Group | Antacid Dosage Guidelines |
|---|---|
| Adults | Take 1 to 2 spoonfuls (5-10 ml, using the first or second line in the dosing cup). Repeat as necessary to a maximum of twelve 5 ml spoonfuls (60 ml) in 24 hours. |
| Children (Aged 3-12) | Give one 5 ml spoonful (first line in the dosing cup). Repeat as necessary to a maximum of six 5 ml spoonfuls (30 ml) in 24 hours. |
| Children Under 3 | To be given only on the strict advice of a doctor. |
Dosage for Constipation (Laxative)
Drink plenty of fresh fluids during the course of your treatment. Do not use this medicine as a laxative for more than 3 days. If a laxative dose is needed every day, or if there is persistent abdominal pain, consult your doctor immediately.
| Age Group | Laxative Dosage Guidelines |
|---|---|
| Adults | Take 30-45 ml (six to nine 5 ml spoonfuls measured in the dosing cup) at bedtime. Repeat nightly, reducing the dose until constipation is relieved. |
| Children (Aged 3-12) | Give 5-10 ml (one to two 5 ml spoonfuls) at bedtime. |
| Children Under 3 | To be given only on the strict advice of a doctor. |
Overdose Warning: Do not take more than the recommended dose. You may experience diarrhoea. If you take too much, contact your doctor or casualty department immediately.
Safety Warnings & Precautions
While this is a widely used and highly trusted household medicine, you must read the enclosed patient information leaflet before use. Do not take this medicine if you have ever had an allergic reaction to magnesium hydroxide, oil of peppermint, or any of the other ingredients.
