Introduction and description


Laxatives are a class of drug used in the treatment of chronic constipation and irritable bowel. In order to keep the illnesses and drugs together, we have separated out those drugs targeted at sufferers of IBS and placed them in the section IBS treatments.

Thus the drugs discussed here are intended to treat constipation only.

In the section on constipation, we have discussed the possible causes of constipation, and the need to treat the cause and not the symptoms. 

One cause of constipation, for example, can be stress.  The sympathetic nervous system and the parasympathetic nervous system govern bowel action.  In the 'fight or flight' mode [sympathetic nervous system - stress], the body automatically shuts down bowel movements as part of the body's preparation to fight the 'dinosaur'.  When greatly relaxed and without fear [parasympathetic nervous system], the body's normal functions - peeing, pooing and digesting return.  This is why indigestion and constipation often go together when you are stressed.


Thus one helpful treatment of constipation is simply to find ways of relaxing more - listening to beautiful music, walking in the countryside, relaxing by painting or being creative - making cakes or gardening for example.  Making love.  

Eating the right food also helps - we have provided some observations below with suggestions, but there are more suggestions under the heading of constipation for healing foods, including the well known Beverley-Travis recipe, which is actually delicious.

You may be surprised by the foods that do help with constipation.  We all know about onions, garlic, rhubarb, and figs, but did you know celery is good too, as are pomegranates [not pomegranate juice, pomegranates, seeds and all]? 


Sorbitol, a naturally occuring sweetener is also a natural laxative.  It works in much the same way as over-the counter and prescribed laxatives, but because it is found in foods, there is little danger of overdosing.  It draws water into the large intestine, thereby stimulating bowel movements.  Sorbitol also appears to have a synergistic action with the bacteria in our stomach, thus helping those whose bacterial balance has become disrupted by illness or the use of antibiotics.  Sorbitol is found in some dried fruits including prunes and was discovered initially in the fresh juice of mountain ash berries in 1872 - Rowanberries. It is found in the fruits of apples, plums, pears, cherries, dates, peaches, and apricots.

I hope you can see that the need for drugs is very questionable. 

Constipation is a common complaint among elderly people, resulting in large amounts of money being spent on laxatives. Strategies for improving patient care while reducing this expenditure include:
(a) counselling patients that daily bowel movements and purging are not essential to good health,
(b) greater use of nonpharmacological measures such as hydration, exercise and dietary fibre, and
(c) considering safety, effectiveness and cost in the selection of a laxative.
The widespread use of stool softeners, magnesium hydroxide ('milk of magnesia') and stimulant laxatives is difficult to justify from the available data. PMID: 7663066

Types of drug

The classes of product are:

  • Softeners, bulk producers, enemas and others – The  bulking agents or roughage, include dietary fibre. Bulk-producing agents cause the stool to be bulkier and to retain more water, and in many ways have a similar effect to the osmotically acting laxatives by drawing water into the intestines.   
  • Osmotically acting laxatives -In the treatment of chronic constipation,  these laxatives draw water into the bowel, causing a cathartic effect through osmotic action.

Both aim to increase the water content and volume of the stools in the bowel, making them softer and easier to pass. Some of the products, like Lactulose is made up of sugar molecules and is partly broken down by the bacteria that live in the lower part of the gut. This leads to the contents of the gut becoming more acidic because there are carboxylic acids among its metabolites, which are not absorbed from the lower bowel. That in turn causes water to be retained in the lower bowel. This increases the amount of water in the stools, softening them and making them easier to pass.

The added volume of gas and flatulence caused by fermentation of the lactulose or other sugars in these products adds to the volume of the fecal material, and makes it easier to expel. The slightly acidic condition of the colon caused by the presence of acids causes active peristalsis. The combined effect of all of these processes “relieves constipation in a very effective manner”.



All side effects including deaths are obtained from the Adverse Drug Reports submitted to the FDA and SEDA and compiled by eHealthme.  The figures apply to the US only and  thus exclude any reactions and deaths in the rest of the world.  Taking some typical drugs within this category, we find the following:

Most common Bisacodyl side effects:

  • Nausea And Vomiting  (180 reports)
  • Nausea  (169 reports)
  • Weakness  (168 reports)
  • Fatigue  (161 reports)
  • Anaemia(152 reports)
  • Breathing Difficulty  (151 reports)
  • Fever (148 reports)
  • Pain  (143 reports)
  • Hypotension(132 reports)
  • Diarrhea (122 reports)

Most common Magnesium sulfate side effects:

  • Pain  (551 reports)
  • Nausea  (534 reports)
  • Hypotension  (505 reports)
  • Stress And Anxiety  (501 reports)
  • Acute Kidney Failure  (492 reports)
  • Fever  (470 reports)
  • Diarrhea (461 reports)
  • Nausea And Vomiting (406 reports)
  • Breathing Difficulty  (404 reports)
  • Pneumonia  (394 reports)

 Many of these side effects are symptomatic of magnesium imbalance and poisoning.


Note that patients were often taking other drugs whilst taking laxatives, for example opioids - which cause constipation - but the figures are worth noting, given the person started off with constipation.

How it works


Although the scouring action of these products may have a long term effect on the balance of the intestinal bacteria, and the use of products containing magnesium may cause magnesium imbalance over time, the hallucinations that people experience in these products are probably caused by dehydration.

There is an explanation for the physical mechanisms in operation during dehydration in the Science section see the Chemistry of dehydration.  But the section on dehydration explains what is functionally happening and why we may get an hallucination.

The risk of getting adverse effects is higher amongst those who misuse laxatives.  For example  some obsessive slimmers use laxatives to purge themselves when they think they have over eaten.  And there is a higher risk of hallucinations from dehydration with children, the elderly, and people already dehydrated from working in dry offices or too hot surroundings. 

At very high doses, all these drugs are acting via  poisoning.


The table below shows the hallucinations for each drug.  The figures have been obtained from eHealthme and are a summary of the Adverse Drug Reports submitted by doctors to the FDA and SEDA.  The table was correct as of mid August 2015.  The links take you to the eHealthme site and an up-to-date list of all side-effects for each drug.

Even if a drug has no hallucinations recorded, we have kept it in the table so that you are still able to cross reference the side effects.
