Stimulant laxatives are a type of medication commonly used to relieve constipation. They work by stimulating the intestines, promoting bowel movements and alleviating the discomfort associated with constipation. This article provides a detailed overview of stimulant laxatives, including their uses, mechanism of action, and potential side effects.
Stimulant laxatives are primarily used to treat occasional or short-term constipation. The most commonly prescribed stimulant laxative is senna, which originates from the senna plant. They are normally taken at night because take around 12 hours to work and therefore people can relieve themself in the morning after.
They can be helpful in situations where constipation is caused by factors such as certain medications, dietary changes, or a lack of physical activity.
These laxatives are typically recommended when other methods, such as dietary fibre, osmotic laxatives like lactulose, increased fluid intake, and lifestyle modifications, have failed to provide relief.
Stimulant laxatives contain active ingredients that directly stimulate the intestines, promoting bowel movements. The active substances in these laxatives work by irritating the lining of the intestines which speeds up the bowel movements or by increasing fluid secretion into the bowel, which softens the stool and facilitates its passage. By enhancing intestinal contractions and increasing bowel activity, stimulant laxatives help to move the stool through the digestive tract, providing relief from constipation.
While stimulant laxatives can effectively relieve constipation, they can also have potential side effects. Common side effects include:
Prolonged or excessive use of stimulant laxatives can lead to dependency, where the body becomes reliant on the laxative to produce regular bowel movements. This dependency can disrupt the natural bowel function and may require additional interventions to restore normal bowel habits.
It is important to note that stimulant laxatives are generally intended for short-term use. Long-term or excessive use should be avoided, as it can lead to complications and further digestive issues. Additionally, stimulant laxatives may interact with certain medications or medical conditions, so it is crucial to consult with a healthcare professional before using them, especially if you have any pre-existing medical conditions or are taking other medications.
Certain individuals should exercise caution or avoid using stimulant laxatives altogether. This includes individuals with intestinal blockage, inflammatory bowel disease, appendicitis, or any other condition affecting the gastrointestinal tract. Pregnant or breastfeeding individuals should also consult with their healthcare provider before using stimulant laxatives, as there may be potential risks or insufficient data regarding their safety during pregnancy or lactation.
Laxatives help relieve constipation. Stimulant laxatives work by irritating the cells lining your intestines. Examples include senna, bisacodyl, and sodium picosulfate. In 2020, a national patient safety review concluded that we needed new regulations to reduce the abuse and overuse of stimulant laxatives obtainable over the counter in the UK.
When people, such as those with eating disorders, try to use stimulant laxatives to lose weight. Using stimulant laxatives for this purpose is extremely dangerous because it can lead to dehydration and an imbalance of electrolytes in your body.
Overusing stimulant laxatives can cause similar issues and lead to the development of a ‘lazy bowel’ where you become dependent on the medication to pass a bowel movement. In severe cases, this may cause problems with the rhythm of your heart and can even be life-threatening. Moreover, stimulant laxatives are not effective at causing weight loss. Overusing stimulant laxatives can cause similar issues and can lead to the development of a ‘lazy bowel’ where you become dependent on the medication to pass a bowel movement.
There are now new age limits and pack size restrictions for stimulant laxatives. Children under 12 should only use stimulant laxatives if a doctor recommends them. Large packs of stimulant laxatives are no longer available from general sale outlets such as supermarkets, convenience stores, and newsagents. Instead, they are now only available behind the counter in pharmacies.
To ensure they are suitable for use, it is required to speak to a suitably trained staff member before purchasing these medications. Small packs are still available for self-selection in pharmacies and general sale outlets. However, they are now only available for adults, not children, and you can only purchase one pack at a time. Small packs can contain enough medication for two short treatment courses. suitable for use. Small packs are still available for self-selection in pharmacies and general sale outlets.

Stimulant laxatives should not be the first point of call for treating constipation. Instead, try implementing lifestyle measures such as increasing the amount of fibre in your diet, increasing exercise levels, and increasing your water intake.
You should speak to your doctor or pharmacist if lifestyle measures are ineffective. They will decide what treatment is appropriate for you. Initially, they will likely recommend a bulk-forming laxative such as Fybogel (ispaghula husk). If you are still constipated, they may recommend you take an osmotic laxative like Movicol (macrogol) or lactulose. These laxatives are milder than stimulant laxatives and cause fewer side effects. Stimulant laxatives are usually only recommended when lifestyle measures and other laxatives have not worked.
