Laxatives: Stimulant Or Depressant?

Depressants, or CNS depressants, are drugs that reduce stimulation and arousal in various areas of the brain. They are commonly used as prescription medicines and illicit substances. On the other hand, laxatives are a type of medicine used to treat constipation. They are available over the counter and by prescription. While both types of drugs can have relaxing effects on the body, they work in different ways and have distinct purposes. So, while laxatives are not classified as depressants, they may be used to counteract the constipating effects of certain depressant medications.

Laxatives are a type of medicine that can treat constipation

There are several types of laxatives, including bulk-forming laxatives, osmotics, stool softeners, lubricants, and stimulants. Most laxatives are available without a prescription and can be purchased over the counter in pharmacies, grocery stores, and online. They may be labelled as laxatives, stool softeners, or fibre supplements.

Laxatives are typically used to treat occasional or short-term constipation. They should be taken as directed to prevent side effects such as bloating, gas, or stomach cramps. It is important to note that taking laxatives for long periods can cause side effects and even worsen constipation. Therefore, it is recommended to make lifestyle changes, such as eating high-fibre foods, taking probiotics, drinking more fluids, and exercising, before resorting to laxatives.

If constipation persists despite lifestyle changes, it may be necessary to try a laxative. However, it is important to consult with a healthcare provider before taking laxatives, especially for those who are pregnant or taking prescription medications, as laxatives can interfere with the effectiveness of certain medicines.

Laxatives are available without a prescription from pharmacies and supermarkets

There are several types of laxatives available on the market, including bulk-forming laxatives, osmotics, stool softeners, lubricants, and stimulants. Bulk-forming laxatives work by increasing the weight of the stool, which stimulates the bowel. They are considered the gentlest type and are the least likely to cause side effects. Osmotic laxatives, on the other hand, draw water from the body into the bowel to soften the stool and make it easier to pass. Stool softeners, also known as emollient laxatives, increase the water and fat absorbed by the stool, making it softer. Lubricant laxatives coat the colon, preventing water absorption and making the passage of stool easier. Stimulant laxatives activate the nerves controlling the muscles in the colon, forcing it into motion.

Laxatives are available in various forms, including pills, powders, liquids, suppositories, and enemas. It is important to follow the instructions on the medication to ensure effectiveness and reduce the risk of side effects. While laxatives can be purchased without a prescription, it is always recommended to consult a healthcare professional before taking them. They may not be suitable for everyone, and overuse can lead to dependency and side effects such as dehydration, diarrhoea, intestinal obstruction, and electrolyte imbalance.

Before taking laxatives, it is advisable to try lifestyle changes such as increasing fibre intake, drinking plenty of fluids, taking probiotics, and exercising regularly. These methods are often effective in relieving constipation and are safer alternatives to laxatives. If these changes do not help, then laxatives may be considered as a short-term solution. However, if constipation persists or occurs frequently, it is important to consult a doctor to rule out any underlying conditions.

There are four main types of laxatives: bulk-forming, osmotic, stimulant, and stool softeners

Laxatives are a category of medications used to address constipation and other gastrointestinal medical conditions. They enhance digestion and promote bowel movements, facilitating the process of bodily excretion. While they are a common treatment for constipation, they are not the only treatment. Lifestyle changes, such as consuming more fluids and fibre-rich foods, are recommended as the initial management strategy.

Bulk-Forming Laxatives

Bulk-forming laxatives add soluble fibre to the stool, drawing water from the body into the stool to make it bigger and softer. This stimulates the colon to contract and push out the stool. They are generally considered the gentlest type of laxative and are often recommended as the first option unless a healthcare provider suggests otherwise. Examples of bulk-forming laxatives include psyllium (Metamucil®), polycarbophil (FiberCon®), and methylcellulose (Citrucel®).

Osmotic Laxatives

Osmotic laxatives pull water from other parts of the body and send it to the colon, softening the stool and making it easier to pass. They are often used as the first treatment option for constipation. Saline laxatives, which contain salt that holds water in the colon, are a type of osmotic laxative. Osmotic laxatives include polyethylene glycol (Gavilax®, MiraLAX®), magnesium hydroxide solution (Dulcolax®, Ex-Lax®, Phillips'® Milk of Magnesia), and glycerin (Colace Glycerin®, Fleet Pedia-Lax®).

Stool Softener Laxatives

Also known as emollient laxatives, stool softeners increase the water and fat absorbed by the stool, making it softer. An example of a stool softener is docusate (Colace®).

Stimulant Laxatives

Stimulant laxatives activate the nerves controlling the muscles in the colon, forcing it to move the stool along. They are typically used when other over-the-counter laxatives have not been effective. Examples of stimulant laxatives include bisacodyl (Dulcolax®) and senna (Fletcher's® Laxative).

Laxative overuse can lead to dependency and side effects such as diarrhoea and intestinal obstruction

Laxatives are medicines that stimulate or facilitate bowel movements. They are available over the counter (OTC) and are typically used to treat constipation. However, overuse of laxatives can lead to dependency and various side effects.

Laxative dependency can develop when the intestines lose muscle and nerve response, resulting in the body becoming reliant on laxatives to have a bowel movement. This can occur with overuse of laxatives, except for bulk-forming laxatives, which are safe for daily use.

One of the most common side effects of laxative overuse is diarrhoea. Diarrhoea can lead to dehydration and electrolyte imbalance, which can be particularly dangerous for children. In addition, certain laxatives, such as those containing methylcellulose, carboxymethylcellulose, polycarbophil, or psyllium, can cause intestinal blockage if not taken with enough fluids.

Other potential side effects of laxative overuse include abdominal cramping, nausea, vomiting, and gastrointestinal irritation. In rare cases, laxative overdose can cause more severe symptoms such as a drop in blood pressure, choking, or even intestinal failure.

To avoid the risks associated with laxative overuse, it is important to use these medications as directed and only when necessary. Healthcare professionals recommend limiting the use of laxatives to occasional or short-term use, typically for up to one week. If constipation persists or becomes chronic, it is advisable to consult a doctor to discuss alternative treatments or lifestyle changes.

Laxatives should not be taken for longer than one to two weeks without medical advice

Laxatives are a type of medicine that can treat constipation. They are available over the counter and on prescription. While they can be effective in treating constipation, they should not be taken for longer than one to two weeks without medical advice. This is because overuse may lead to dependency and side effects.

Healthcare professionals do not typically prescribe laxatives for long-term use. They are designed to be used occasionally and for up to one week at a time. If your constipation has not improved after taking laxatives for a week, speak to a doctor.

Laxatives can cause side effects such as dehydration, which can make you feel lightheaded and give you headaches and darker urine. Overuse can also cause diarrhoea, intestinal obstruction, and an imbalance of salts and minerals in the body.

If you are still experiencing constipation after making lifestyle changes such as increasing your fibre intake, drinking more water, and exercising regularly, speak to a doctor. They may recommend a different treatment or advise you to take laxatives for longer than one week, but this should be done under medical supervision.

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