Osmotic laxatives are not recommended for children unless advised by a doctor
Osmotic laxatives are a type of medication that can be used to treat constipation in children. They work by drawing water into the stool, making it softer and easier to pass. While they are generally considered safe for children, they should only be used under the guidance of a healthcare professional.
There are a variety of osmotic laxatives available for children, including:
- Polyethylene glycol (MiraLAX, Dulcolax Balance)
- Magnesium hydroxide (Milk of Magnesia)
- Lactulose (Constulose, Enulose, Generlac, Kristalose)
- Sorbitol
- Sodium acid phosphate (OsmoPrep, Visicol)
These laxatives are typically well-tolerated by children and can be used for prolonged periods without risk. However, it is important to follow the recommended dosage and administer them with enough water to avoid worsening constipation.
While osmotic laxatives can be effective in treating constipation, they should not be the first line of treatment. It is recommended to try dietary and lifestyle changes first, such as increasing fiber and fluid intake, before resorting to laxatives. Making these changes can often help relieve constipation without the need for medication.
In addition, laxatives can have side effects, such as diarrhea, abdominal cramping, and bloating. Therefore, it is important to consult a healthcare professional before giving your child any type of laxative to ensure it is safe and appropriate for their needs.
Relieving Constipation: What to Take

Osmotic laxatives are available over the counter and by prescription
There are several types of osmotic laxatives, each with different active ingredients. Polyethylene glycol (PEG), for example, is an organic compound derived from petroleum that is safe to ingest and can be purchased over the counter under brand names like Miralax and GlycoLax. Lactulose, on the other hand, is a type of sugar that is not absorbed by the intestine. It is available by prescription and includes brands like Cephulac, Duphalac, and Kristalose.
Sorbitol is another sugar with a similar action to lactulose, and it is available both over the counter and by prescription. Magnesium citrate, a salt form of magnesium combined with citric acid, is also available over the counter. Finally, there is magnesium hydroxide, a milder form of magnesium sold as Milk of Magnesia, which is available over the counter and also acts as an antacid.
It is important to note that, while osmotic laxatives can be purchased without a prescription, it is always recommended to consult a healthcare provider to ensure safe and correct usage.

Osmotic laxatives are used to treat or prevent constipation
Osmotic laxatives are medications used to treat or prevent constipation. They work by drawing water from the rest of the body into the bowel, softening the stool and making it easier to pass. Osmotic laxatives are available over the counter and by prescription. Examples include Milk of Magnesia, lactulose, and polyethylene glycol (PEG).
Constipation occurs when stools are infrequent and hard to pass. They are usually hard and dry. Osmotic laxatives can help relieve constipation by increasing the amount of fluid in the intestines, which softens the stools. The term "osmotic" refers to the movement of a fluid through a membrane so that the concentration is equal on both sides. This is how osmotic laxatives work.
In people with constipation, the concentration of water in the wall of the colon and the inside of the colon (called the lumen) is balanced but too low to compensate for hard, dry stools. This is especially true for people who do not consume enough water. Osmotic laxatives alter the balance with substances such as salts, sugars, and other organic compounds that encourage the movement of water into the lumen.
In addition to treating constipation, osmotic laxatives are sometimes used for bowel preparation (to cleanse the bowel of stool) before a colonoscopy. They can also be used to prevent or treat chronic constipation, while other types of laxatives are generally used for the treatment of occasional constipation.
There are several common osmotic laxatives available, each with different active ingredients. Polyethylene glycol (PEG) is an organic compound derived from petroleum that can be safely ingested to manage constipation. It is available over the counter under brand names such as Miralax and GlycoLax. Lactulose is a type of sugar that is not absorbed by the intestine. It sits and ferments in the intestines, producing fatty acids that draw water into the lumen. It is available by prescription under brand names including Cephulac, Duphalac, and Kristalose.
Sorbitol is another non-absorbable sugar with an action similar to lactulose. It is available over the counter and by prescription under brand names such as Arlex and GeriCare. Magnesium citrate is magnesium in salt form combined with citric acid. The salts help draw water into the lumen. Over-the-counter versions include Citrate of Magnesia, Citroma, and LiquiPrep. Magnesium hydroxide, sold under the brand name Milk of Magnesia, is a milder form of magnesium. It is available over the counter and is also used as an antacid.
Osmotic laxatives can cause side effects such as nausea, bloating, cramping, flatulence, and diarrhoea. Overuse can lead to dehydration and the loss of electrolytes like sodium, calcium, and potassium. These minerals are essential for regulating heartbeats, muscle contractions, and other key functions in the body. Therefore, it is important to follow the dosing instructions carefully and only use a laxative when needed.

Osmotic laxatives are not suitable for long-term use
While osmotic laxatives can be effective in treating constipation, they can also cause side effects such as dehydration and the loss of electrolytes like sodium, calcium, and potassium. These minerals are essential for regulating heartbeats, muscle contractions, and other key functions in the body.
In addition, the overuse of osmotic laxatives can lead to other potentially serious complications. Therefore, it is important to follow the dosing instructions carefully and only use them when needed. If you are experiencing chronic constipation, it is recommended to see a healthcare provider to identify the underlying cause and explore other treatment options.
Furthermore, osmotic laxatives should not be used daily to ease constipation as this can be harmful. Instead, it is advisable to make lifestyle changes, such as increasing your daily intake of fibre and water, as well as regular exercise, to prevent constipation.

Osmotic laxatives can cause dehydration and loss of electrolytes
Osmotic laxatives are used to treat constipation by drawing water into the colon, softening stools, and making them easier to pass. However, their overuse can lead to dehydration and the loss of essential electrolytes.
Dehydration
Osmotic laxatives can cause dehydration because they draw water from the wall of the colon into the inside of the colon (lumen). This movement of fluid helps to soften stools and treat constipation. However, if used excessively, they can deplete the body of water, leading to dehydration. Dehydration can cause a range of symptoms, including lightheadedness, headaches, and dark-coloured urine.
Electrolyte Loss
Electrolytes are essential minerals, including sodium, calcium, and potassium, which the body needs to regulate vital functions such as heartbeats and muscle contractions. Osmotic laxatives can cause a loss of electrolytes, leading to an electrolyte imbalance in the body. This imbalance can have serious consequences, including tremors, vomiting, urinary tract infections, kidney failure, muscle spasms, and heart attacks.
Prevention
To prevent dehydration and electrolyte loss, it is important to use osmotic laxatives as directed and only when needed. They should not be used daily or for extended periods without medical supervision. It is also crucial to drink plenty of fluids when taking osmotic laxatives and to follow a fibre-rich diet to optimise digestive health.
