Best Laxatives In The Uk: Quick And Effective Relief

Laxatives are a type of medicine used to treat constipation. They are available over-the-counter without a prescription and can be bought from pharmacies and supermarkets. There are four main types of laxatives: bulk-forming laxatives, osmotic laxatives, stimulant laxatives, and stool softener laxatives. Each type works differently, and the best laxative for an individual may depend on their specific needs and preferences. Some laxatives are available as tablets or capsules, while others come in the form of suppositories, liquids, or gels. It is important to follow the recommended dosage and not to overuse laxatives, as this can lead to side effects and health complications.

Characteristics and Values Table for the Best Laxatives in the UK

Bulk-forming laxatives

Some popular bulk-forming laxatives available in the UK include:

• Fybogel (ispaghula husk)
• Metamucil (psyllium)
• FiberCon (polycarbophil)
• Citrucel (methylcellulose)
• Benefiber (wheat dextrin)

Osmotic laxatives

Some common osmotic laxatives include:

• Polyethylene glycol (PEG): An organic compound derived from petroleum that can be safely ingested to manage constipation. Available over the counter, PEG-containing laxatives include Miralax and GlycoLax.
• Lactulose: 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. Available by prescription, lactulose-containing laxatives include Cephulac, Duphalac, and Kristalose.
• Sorbitol: Another non-absorbable sugar with an action similar to lactulose. Available in over-the-counter and prescription versions, including Arlex and GeriCare.
• Magnesium citrate: 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: A milder form of magnesium sold under the brand name Milk of Magnesia. Available over the counter, Milk of Magnesia is also used as an antacid.

Stimulant laxatives

It is important to note that stimulant laxatives should not be used for more than a week unless specifically advised by a doctor. They can be habit-forming, and prolonged use can be harmful to the bowels. Additionally, they should not be given to children under six years old without a paediatrician's instruction.

Before using stimulant laxatives, it is recommended to consult a doctor, especially if you have any current health conditions, are pregnant, or are breastfeeding.

Stool softener laxatives

Stool softeners are available in the form of oral softgel capsules, as well as rectal enemas and suppositories. The active ingredients in stool softeners are docusate sodium and docusate calcium, with Colace® being a common brand of docusate.

It is important to note that stool softeners should only be taken when needed and as directed by a healthcare provider. They are typically taken at bedtime and can take between 12 to 72 hours to start working. It is not recommended to take stool softeners for more than a week without consulting a doctor.

Side effects of stool softeners may include stomach pain, nausea, and diarrhoea. If you experience any serious side effects, such as hives, swelling of the face, tongue, or throat, or difficulty swallowing or breathing, it is important to seek medical advice immediately.

Before taking stool softeners, it is important to consult a healthcare professional, especially if you are taking other medications, as they can interfere with the effects of other drugs. Stool softeners are generally not recommended for children unless advised by a doctor.

Laxatives for children

Laxatives are medications that can help treat and prevent constipation. They work by either softening the stool or stimulating a bowel movement. They are relatively safe to use with children, but it is always best to check with a medical professional before administering any medication.

When to use laxatives

Constipation is common in children, but it can be worrying for parents. Before using laxatives, it is recommended to try lifestyle changes, such as adding more water and fibre to the child's diet, and increasing physical activity. If these changes do not help, a laxative may be needed.

Types of laxatives

There are several types of over-the-counter laxatives that are suitable for children:

• Osmotic laxatives: These draw water into the stool to help it move through the colon quicker. Polyethylene glycol (found in Miralax) is the most commonly used osmotic laxative. It is tasteless, well tolerated by children, and can be used in infants younger than 6 months old.
• Bulking agents: These are fibre supplements that raise the amount of water absorbed in the stool, making it easier to pass. Examples include psyllium (Metamucil) and calcium polycarbophil (Fibercon).
• Stool softeners: These increase the amount of water and fat in the stool, making it softer and easier to pass. Examples include docusate (Colace), which is not recommended for daily, long-term use.
• Stimulant laxatives: These increase the movement of the intestines to help the child pass a stool. Examples include bisacodyl (Dulcolax).
• Lubricants: These help the stool slide out more easily. Mineral oil is the most commonly used lubricant and is typically used in children over 3 years old.
• Rectal therapies: Suppositories and enemas are placed in the rectum and produce results within minutes. They are not meant for regular or long-term use.

Natural laxatives

Before trying laxatives, it may be worth trying some natural remedies:

• Increasing water intake: Make sure your child is drinking enough water. The suggested daily water intake for children by age is: 4-8 oz for 6-12-month-olds; about 4 cups for 1-3-year-olds; about 5 cups for 4-8-year-olds; and about 8 cups for 8 years and older.
• Increasing fibre intake: Your child should eat at least five servings of fruits and vegetables per day. Excellent sources of fibre include peas, carrots, and pears. Other good sources include leafy greens, broccoli, beets, asparagus, fruits or fruit purees, and whole-grain foods.

Side effects and risks

Laxatives are generally safe for children, but there can be side effects, including:

• Worsening constipation if not taken with enough water (bulking agents)
• Diarrhoea (osmotic laxatives)
• Rectal discomfort (enemas or suppositories)

There have also been concerns about a possible link between osmotic laxatives and behavioural changes in children, but this has not been proven.

Laxatives should be used with caution or avoided in children with certain medical conditions, such as electrolyte imbalance or a history of bowel obstruction. It is always best to check with a healthcare professional before giving your child a laxative.
