Understanding Laxative Medications: How They Work and Their Effectiveness

Laxative medications are commonly used to relieve constipation, a condition characterised by infrequent bowel movements or difficulty passing stools.

These medications help stimulate bowel movements and facilitate smoother and more regular elimination. In this blog post, we will explore what laxative medications are, 

How they work, their effectiveness, and highlight some well-known brands that provide these medications.

What are Laxative Medications? 

Laxative medications are substances or drugs designed to promote bowel movements and alleviate constipation. They work by either increasing the water content in the stool, adding bulk to the stool, or stimulating the muscles of the intestines to contract and propel the stool forward.

Types of Laxative Medications 

There are several types of laxative medications available, including:

  1. Bulk-forming laxatives: These laxatives contain fiber that absorbs water, softening the stool and adding bulk to it. Examples include psyllium husk (Isabgol) and methylcellulose.
  1. Osmotic laxatives: These medications work by drawing water into the intestines, making the stool softer and easier to pass. Common osmotic laxatives include magnesium hydroxide, polyethylene glycol, and lactulose.
  1. Stimulant laxatives: Stimulant laxatives stimulate the muscles of the intestines, promoting bowel movements. They work by irritating the lining of the intestines, causing contractions. Examples include senna and bisacodyl.
  1. Stool softeners: These laxatives soften the stool by allowing the stool to absorb more water. Docusate sodium is a popular stool softener.

Effectiveness of Laxative Medications 

The effectiveness of laxative medications can vary depending on the type of laxative used, the individual’s response, and the underlying cause of constipation. In general, laxative medications can provide relief for short-term constipation. 

Bulk-forming laxatives and osmotic laxatives are considered gentle and are often recommended as a first-line treatment. They can help soften the stool and promote regular bowel movements without causing dependency.

Stimulant laxatives are more potent and are typically used for short-term relief, as prolonged use can lead to dependence and reduced effectiveness. Stool softeners are generally well-tolerated but may not be as effective in cases of severe constipation.

It is important to note that while laxative medications can provide temporary relief, they do not address the underlying causes of chronic constipation. Lifestyle changes, such as increasing fiber intake, drinking enough water, and exercising regularly, are essential for long-term management.

For how long should I use laxatives?

Take laxatives only on occasion and for no more than a week at a time.

Stop using laxatives after your constipation has improved.

Consult your doctor if your constipation hasn’t eased after a week of using laxatives.

Following the use of a laxative, you can undertake the following lifestyle modifications to help prevent constipation:

  • Consuming plenty of water
  • Regular exercise
  • Increased fiber consumption

These are more effective methods of preventing constipation than laxatives.

Taking laxatives every day to relieve constipation can be dangerous.

If you’re still constipated despite adopting lifestyle modifications, see your doctor.

In some situations, a laxative may be given for frequent usage, but this should always be under the supervision of a GP or gastroenterologist (an expert in gut disorders).

Laxative Side Effects

Laxatives, like most medications, can have side effects. They are normally moderate and will go away after you stop taking the laxative.

The following are frequent adverse effects of most laxatives that you may experience depending on the type of laxative you are taking:

Bloating, farting, tummy pains, feeling nauseous, dehydration, which can cause lightheadedness, headaches, and pee that is a deeper colour than usual.
