Laxatives: Quick Relief Or Cause For Concern?

Laxatives are a type of medicine used to treat constipation. They are typically used when lifestyle changes, such as increasing fibre intake, drinking more fluids, and exercising, have not helped. Laxatives work by softening stools or stimulating the bowels to promote bowel movement. While they are generally safe and effective, it is important to use them as directed to prevent side effects such as bloating, gas, and stomach cramps.

The speed at which a laxative works depends on its type and route of administration. Rectal laxatives, such as suppositories and enemas, act faster than oral laxatives, providing relief within minutes to hours. However, they also carry a higher risk of side effects, including diarrhoea, abdominal cramps, and rectal irritation. Oral laxatives, on the other hand, take longer to work, typically within 12 hours to 3 days, but are gentler on the body.

Laxatives work by softening stools or stimulating the bowels

Laxatives are a type of medicine used to treat constipation. They are often used if lifestyle changes, such as increasing fibre intake, drinking more fluids, and exercising, have not helped. They are available over the counter without a prescription and can be bought from pharmacies and supermarkets. They are also available on prescription from a doctor.

There are four main types of laxatives: bulk-forming, osmotic, stimulant, and stool softener. Bulk-forming laxatives increase the bulk or weight of the stool, which stimulates the bowel. Osmotic laxatives draw water from the body into the bowel to soften the stool. Stool softeners increase the fluid content of the stool, making it softer and easier to pass. Stimulant laxatives speed up the movement of the bowels.

The speed at which laxatives work depends on the type and how they are taken. Laxatives administered rectally, such as enemas and suppositories, work the fastest, usually within minutes to an hour. However, they are more likely to cause side effects such as stomach cramps, diarrhoea, and rectal irritation. Oral laxatives, such as saline and stimulant laxatives, typically work within 12 hours. Gentler laxatives, like bulk-forming and osmotic laxatives, usually take a few days to work but are less likely to cause side effects.

They are available over the counter or by prescription

Laxatives are available over the counter or by prescription. They are used to treat constipation and can be taken orally or administered rectally.

Over-the-counter laxatives are available in pharmacies, grocery stores, and online. They are typically recommended when lifestyle changes, such as increasing fibre intake, drinking more fluids, and exercising, have not helped with constipation. These include:

• Bulk-forming laxatives: These increase the weight of the stool, stimulating the bowel. Examples include Fybogel (ispaghula husk) and unprocessed bran.
• Osmotic laxatives: These draw water into the bowel to soften the stool and make it easier to pass. Examples include lactulose (Duphalac, Lactugal) and macrogol (Movicol, Laxido).
• Stimulant laxatives: These stimulate the nerves and muscles in the bowel to help move the stool along. Examples include bisacodyl (Dulcolax) and senna (Senokot).
• Stool softener laxatives: These allow water into the stool to soften it and make it easier to pass. An example is docusate (Colace).

Prescription laxatives are usually considered when over-the-counter options are ineffective or if the patient has a chronic condition causing constipation, such as irritable bowel syndrome (IBS) or when taking opioids. Some examples of prescription laxatives include:

• Lactulose (Duphalac)
• Linaclotide (Linzess)
• Lubiprostone (Amitiza)
• Prucalopride (Prudac, Motegrity)
• Plecanatide (Trulance)

It is important to follow the instructions on the package to avoid side effects and overuse, which can lead to laxative dependence and other health issues.

They come in different forms, including pills, capsules, liquids, suppositories and enemas

Laxatives are a type of medicine used to treat constipation. They are available in different forms, including pills, capsules, liquids, suppositories, and enemas. Each form has its own advantages and considerations:

Pills and Capsules

Pills and capsules are taken orally and are generally convenient and comfortable for most people. They are typically swallowed with water and can be taken discreetly. However, it is important to follow the instructions on the packaging or provided by a healthcare provider to ensure proper usage.

Liquids or Syrups

Liquid laxatives offer an alternative for those who have difficulty swallowing pills or capsules. They are measured out and drunk, often mixed with water or other liquids. This form may be preferred by individuals who find it challenging to take solid medications.

Suppositories

Suppositories are tiny dissolvable capsules inserted directly into the rectum. They are manually inserted and may be less convenient or pleasant than oral options, but they often provide faster relief. This form is also suitable for individuals with swallowing difficulties.

Enemas

Enemas are another form of rectally administered laxatives. They are contained in small squeezable tubes, and the medicine is injected into the rectum by squeezing the tube. Enemas provide rapid relief but come with a higher risk of side effects such as diarrhoea and stomach cramps. They may also be less comfortable or more challenging to use for some individuals.

It is important to remember that laxatives should be used as directed and not overused. They are typically recommended when lifestyle changes, such as increasing fibre intake, drinking more fluids, and exercising, have not helped with constipation. If constipation persists or is accompanied by other symptoms, it is advisable to consult a healthcare provider.

They are not suitable for everyone and can cause side effects

Laxatives are not suitable for everyone and can cause side effects. They are not usually recommended for children unless advised by a doctor. People with certain health conditions, such as Crohn's disease or ulcerative colitis, should also refrain from using laxatives. It is important to read the patient information leaflet that comes with the medicine to ensure it is safe for you to take.

Laxatives can cause side effects, although they are usually mild and should pass once you stop taking the medication. Common side effects include dehydration, which can make you feel lightheaded, have a headache, and have darker-coloured urine. Other side effects may include diarrhoea, abdominal pain, decreased weight, weakness, rectal irritation, burning, itching, nausea, and allergic reactions.

Using laxatives too frequently or for too long can lead to laxative dependence, where your body becomes unable to have a bowel movement without the use of the product. It can also cause intestinal obstruction and an imbalance of salts and minerals in your body. Overuse of laxatives can result in an electrolyte imbalance, which can contribute to heart and kidney problems.

It is important to follow the instructions on the package to avoid these side effects and never take more than the recommended dose. Laxatives should only be used temporarily and are not meant to be taken every day. If you experience any persistent or troublesome side effects, consult your healthcare provider.

They should be used sparingly and only when necessary

Laxatives are a group of medications used to treat constipation. They are available in many different over-the-counter brand-name and generic products. They come in different forms, with both oral (tablets, capsules, and liquids) and rectal (enemas and suppositories) options.

Laxatives should be used sparingly and only when necessary. They are not a first-line treatment for constipation and are meant to be used occasionally and for up to a week at a time. It is recommended to stop taking a laxative as soon as your constipation improves. This is because they can have side effects and may lead to laxative dependence if overused.

Laxatives should not be used as a replacement for a healthy diet and regular exercise, which are the best ways to prevent constipation. Eating high-fibre foods, drinking plenty of fluids, and exercising regularly are often enough to relieve constipation. If these lifestyle changes do not help, then it may be time to consider taking a laxative.

It is important to remember that laxatives are not suitable for everyone. They are not usually recommended for children unless advised by a doctor. Additionally, people with certain health conditions, such as Crohn's disease or ulcerative colitis, should use laxatives with caution.

Before taking a laxative, it is essential to read the patient information leaflet that comes with the medicine to ensure it is safe for you. It is also important to drink plenty of fluids when taking laxatives, as they can cause dehydration.
