Duphalac (lactulose)

Duphalac is used to treat chronic constipation.

Take this medication exactly as prescribed by your doctor. Do not take it in larger amounts or for longer than recommended. Follow the directions on your prescription label.

Measure liquid medicine with a special dose-measuring spoon or cup, not a regular table spoon. If you do not have a dose-measuring device, ask your pharmacist for one.

The liquid form of lactulose may become slightly darken in color, but this is a harmless effect. However, do not use the medicine if it becomes very dark, or if it gets thicker or thinner in texture.

Lactulose powder should be mixed with at least 4 ounces of water. You may also use fruit juice or milk to make the medication better.

It may take up to 48 hours before you have a bowel movement after taking lactulose.

If you use lactulose over a long period of time, your doctor may want you to have occasional blood tests. Do not miss any scheduled appointments. Store lactulose at room temperature away from moisture and heat.

Lactulose is a type of sugar. It is broken down in the large intestine into mild acids that draw water into the colon, which helps soften the stools.

If you miss a dose of Duphalac and you are using it regularly, use it as soon as possible. Do not use 2 doses at once.

Store at the room temperature away from moisture and sunlight. Keep out of reach of children.

You should not use this medication if you are on a special diet low in galactose (milk sugar).

Before taking lactulose, tell your doctor if you have diabetes or if you need to have any type of intestinal test using a scope (such as a colonoscopy).
