Phillips Milk of Magnesia is used for a short time to treat occasional constipation. It is a laxative (osmotic-type) that is thought to work by drawing water into the intestines, an effect that helps to cause movement of the intestines within 30 minutes to 6 hours. Extended use or overuse of this medication for constipation may result in dependence on laxatives and ongoing constipation. Overuse may also cause diarrhea that doesn't go away, dehydration and mineral imbalances (such as high magnesium). For constipation problems, it may take 30 minutes to 6 hours to produce a bowel movement. Stop the product if this product does not produce a bowel movement, if you need to use this medication or other laxative products regularly for more than 1 week, or if you have rectal bleeding.Precautions:✓ Keep out of reach of children✓ Do not use if allergic to the product.✓ Do not use if you have stomach pain, nausea or vomiting.✓ Kidney diseases✓ Rectal bleeding.Directions:✓Adults and children 12 years and older: 30ml to 60ml once a day, preferably at bedtime.✓ Children 6 to 11 years: 15ml to 30 ml once a day, preferably at bedtime.✓ Shake well before use.✓ Drink a full glass of water after each dose.
