What Are Constipation Relief Tablets and How Do They Help?

 

Constipation is something most people experience at some point. It can leave you feeling bloated, uncomfortable, and frankly a bit miserable. constipation relief tablets like Almus Constipation Relief Adult 20 Tablets offer a straightforward, affordable option when dietary changes and increased fluid intake haven't done the trick. Each tablet contains bisacodyl 5mg — a well-established stimulant laxative used widely across the UK. At just £3.79 for 20 tablets, this is a practical choice for occasional constipation in adults.

Constipation is defined by the NHS as passing fewer than three stools per week, or stools that are hard, dry, and difficult to pass. It affects people of all ages and can be triggered by a low-fibre diet, dehydration, lack of physical activity, or certain medicines. If you're looking for more options to manage gut-related discomfort, you might also want to explore our IBS and Cramps range alongside this product.

 

How Does Almus Constipation Relief Work in the Body?

 

Bisacodyl belongs to a class of medicines called stimulant laxatives. It works directly on the lining of the large intestine (colon) to encourage bowel movement. Here's what happens after you take a tablet:

  • Bisacodyl is absorbed in the small intestine and converted to its active form.
  • It stimulates the nerve endings in the colon wall, triggering muscle contractions (peristalsis).
  • These contractions push stool towards the rectum.
  • It also reduces water absorption from the colon, softening the stool and making it easier to pass.

The tablets are enteric-coated, which means they're designed to pass through the stomach intact and dissolve in the intestine. This is why you must not crush, chew, or break them — and why you should avoid taking them with milk or antacids, which can dissolve the coating too early.

 

Who Is Almus Constipation Relief Suitable For?

 

This product is intended for adults and children aged 4 years and over, though the dosing differs by age group. It's designed for short-term, occasional use — not as a daily habit. It's particularly suited to:

  • Adults experiencing occasional constipation not relieved by dietary changes.
  • People who need a reliable overnight laxative effect (taken at bedtime).
  • Those preparing for certain medical procedures where bowel clearance is needed (under medical guidance).
  • Individuals who prefer a tablet form over liquid laxatives.

It is not suitable for people with bowel obstruction, inflammatory bowel conditions such as Crohn's disease or ulcerative colitis, or those with severe abdominal pain of unknown cause. Always speak to your pharmacist if you're unsure whether this product is right for you.

Specifications of Almus Constipation Relief Adult 20 Tablets

 

What Is Almus Constipation Relief and What Is It Used For?

 

Almus Constipation Relief Adult 20 Tablets contain bisacodyl 5mg as the active ingredient. Bisacodyl is a stimulant laxative used to treat occasional constipation in adults and children aged 4 and over. It is taken by mouth and works within 6 to 12 hours, making it ideal for taking at bedtime to produce a bowel movement the following morning. This product is available over the counter without a prescription and is classified as a General Sale List (GSL) medicine in the UK.

 

What Do You Need to Know Before Using Almus Constipation Relief?

 

Before taking these tablets, it's important to check whether they are appropriate for you. Do not take Almus Constipation Relief if any of the following apply:

  • You have a known allergy to bisacodyl or any other ingredient in the tablet.
  • You have a bowel obstruction or ileus (paralysis of the bowel).
  • You have severe abdominal pain, nausea, or vomiting of unknown cause.
  • You have inflammatory bowel disease such as Crohn's disease or ulcerative colitis.
  • You are severely dehydrated.
  • You have a rare hereditary condition such as galactose intolerance (check the full PIL for excipients).

You should also be aware of the following potential drug interactions:

  • Antacids and milk: Taking bisacodyl within one hour of antacids or dairy products can dissolve the enteric coating prematurely, causing stomach irritation and reducing effectiveness.
  • Diuretics and corticosteroids: Concurrent use may increase the risk of electrolyte imbalance, particularly low potassium (hypokalaemia).
  • Other laxatives: Combining stimulant laxatives with other laxative types should only be done under medical guidance.

If you are pregnant, breastfeeding, or trying to conceive, speak to your doctor or pharmacist before use. The NHS advises that constipation during pregnancy is common and that treatment options should be discussed with a healthcare professional.

 

How Should You Use Almus Constipation Relief?

 

Always read the patient information leaflet supplied with the pack before taking this medicine. Follow these steps carefully:

  3. Take at bedtime for a bowel movement the following morning.
  4. Do not exceed the recommended dose for your age group.
  5. Do not use for more than 5 consecutive days without speaking to a doctor.

Frequently Asked Questions

No prescription is needed as this is an over-the-counter medicine. Simply add it to your basket and it will be dispatched to your door. You can also browse our full constipation range for related products.

How do Almus Constipation Relief tablets work in the body?

Each tablet contains bisacodyl 5mg, a stimulant laxative that acts directly on the nerve endings in the wall of the large intestine. This triggers muscle contractions that push stool towards the rectum. Bisacodyl also reduces water reabsorption in the colon, which softens the stool and makes it easier to pass.

How long does it take for Almus Constipation Relief to work?

When taken orally at bedtime, bisacodyl tablets typically produce a bowel movement within 6 to 12 hours. Most people find they work overnight, with a result the following morning. If you don't experience a bowel movement within 12 hours, do not take an additional dose without speaking to a pharmacist first.

What is the correct dose of Almus Constipation Relief for adults?

The standard adult dose is 1 to 2 tablets (5mg to 10mg) taken once daily at bedtime. You should not exceed 2 tablets in any 24-hour period. For children aged 4 to 9 years, the dose is 1 tablet only — always check the patient information leaflet for full age-specific guidance.

What is the best time to take Almus Constipation Relief tablets?

The recommended time to take these tablets is at bedtime. This allows the 6 to 12 hour onset period to pass overnight, so you're likely to have a bowel movement in the morning. Avoid taking them with milk, dairy, or antacids, as these can interfere with the enteric coating.

Can I take Almus Constipation Relief tablets during pregnancy?

You should consult your doctor or pharmacist before taking bisacodyl if you are pregnant or breastfeeding. Constipation is common during pregnancy, but not all laxatives are suitable for use at every stage. A healthcare professional can advise on the safest option for your individual circumstances.

Who should not take Almus Constipation Relief tablets?

This product is not suitable for people with bowel obstruction, inflammatory bowel disease (such as Crohn's disease or ulcerative colitis), severe abdominal pain of unknown cause, or known allergy to bisacodyl. Children under 4 years of age should not take this product. Always read the full patient information leaflet before use.

What are the side effects of Almus Constipation Relief tablets?

The most common side effects include abdominal cramps, diarrhoea, nausea, and rectal discomfort. Less commonly, some people may experience dizziness or electrolyte imbalance with prolonged use. If you develop severe abdominal pain or notice rectal bleeding, stop taking the tablets and seek medical advice promptly.

How do I manage side effects of Almus Constipation Relief?

Mild abdominal cramps are common and usually short-lived — they typically resolve once you've had a bowel movement. Staying well hydrated can help reduce discomfort. If diarrhoea persists or you feel unwell, stop use and speak to your pharmacist. You can also explore our diarrhoea range if needed.

How long can you take Almus Constipation Relief for?

Almus Constipation Relief should not be used for more than 5 consecutive days without consulting a doctor or pharmacist. Stimulant laxatives are intended for short-term, occasional use only. Long-term or frequent use without medical supervision can lead to dependence and electrolyte imbalances.

What happens if I miss a dose of Almus Constipation Relief?

If you forget to take a dose, simply take it the following night at bedtime as usual. Do not take a double dose to make up for a missed one. Because this product is used on an as-needed basis for occasional constipation, missing a single dose is unlikely to cause any problems.

Can I take Almus Constipation Relief with other medicines?

You should avoid taking bisacodyl within one hour of antacids or milk, as these can dissolve the enteric coating prematurely. If you are taking diuretics or corticosteroids, there is a potential risk of electrolyte imbalance. Always tell your pharmacist about all medicines you are currently taking before starting a new product.

What are the alternatives to Almus Constipation Relief tablets?

Alternatives include bulk-forming laxatives such as ispaghula husk (e.g. Fybogel), osmotic laxatives such as lactulose or macrogol (e.g. Movicol), and stool softeners such as docusate sodium. The right choice depends on the cause and severity of your constipation — your pharmacist can help you decide. Browse our full constipation collection for more options.

Is Almus Constipation Relief suitable for IBS-related constipation?

Stimulant laxatives like bisacodyl are generally not the first-line recommendation for IBS-related constipation. The NHS typically advises dietary changes, increased fluid intake, and bulk-forming laxatives first. If you have IBS, speak to your GP or pharmacist before using this product, and consider exploring our IBS and Cramps range for more targeted options.

What are the latest guidelines on using bisacodyl for constipation?

Current NHS and NICE guidance recommends that stimulant laxatives such as bisacodyl are appropriate for short-term relief of constipation when dietary and lifestyle measures have not been effective. They are considered safe for occasional use in adults and children aged 4 and over when used as directed. Always follow the patient information leaflet and seek advice if symptoms persist beyond 5 days.

How Should You Use Almus Constipation Relief?

Always read the patient information leaflet before taking this medicine. Swallow each tablet whole — never crush, chew, or break it, as the enteric coating is essential for the tablet to work correctly in the intestine rather than the stomach. Take with a full glass of water and avoid consuming milk, dairy products, or antacid medicines within one hour of taking your dose.

Follow these steps each time you take a dose:

What Is the Correct Dose of Almus Constipation Relief?

The dose varies depending on age. Always use the lowest effective dose and do not exceed the maximum stated dose. If you are unsure which dose applies to you, speak to your pharmacist before taking this medicine.

When Is the Best Time to Use Almus Constipation Relief?

The recommended time to take Almus Constipation Relief is at bedtime. Because bisacodyl takes 6 to 12 hours to work after oral administration, taking it in the evening means you're likely to experience a bowel movement the following morning — which fits naturally into most people's daily routines. Avoid taking it immediately after a meal that includes dairy products or alongside antacid medicines.

How Long Can You Use Almus Constipation Relief For?

This product is intended for short-term, occasional use only. Do not take it for more than 5 consecutive days without first speaking to your doctor or pharmacist. If constipation persists beyond this period, it may indicate an underlying condition that requires further investigation. Long-term reliance on stimulant laxatives without medical supervision is not recommended, as it can affect normal bowel function over time.

Do not exceed the recommended dose. If in doubt, speak to your pharmacist.

What Are the Most Common Side Effects of Almus Constipation Relief?

Most people tolerate bisacodyl well when taken at the recommended dose for a short period. However, some side effects can occur. The most common ones are related to the stimulant action of the medicine on the bowel.

  • Abdominal cramps or stomach pain
  • Diarrhoea
  • Nausea
  • Rectal discomfort or irritation
  • Feeling of urgency to open the bowels

What Are the Less Common Side Effects of Almus Constipation Relief?

Less commonly, some people may experience side effects that are not directly related to bowel activity. These are more likely to occur if the product is used for longer than recommended or at higher than advised doses.

  • Dizziness or light-headedness, particularly when standing up quickly after a bowel movement
  • Electrolyte imbalance (e.g. low potassium levels) with prolonged use
  • Skin rash, itching, or other signs of an allergic reaction
  • Fluid loss leading to dehydration if diarrhoea is prolonged

What Are the Serious Side Effects of Almus Constipation Relief?

Serious side effects are rare but require immediate attention. Stop taking the tablets straight away and seek medical advice if you notice any of the following:

  • Severe or persistent abdominal pain
  • Rectal bleeding or blood in your stool
  • Signs of a severe allergic reaction — including swelling of the face, lips, tongue, or throat, difficulty breathing, or a widespread skin rash
  • No bowel movement at all after taking the tablets

What Should You Do If You Experience Side Effects?

Mild side effects such as brief abdominal cramps are common and usually resolve once you've had a bowel movement. Staying well hydrated is important, especially if you experience diarrhoea. If side effects are troublesome or persist, stop taking the tablets and speak to your pharmacist or GP. You can also report suspected side effects directly to the MHRA via the Yellow Card scheme at yellowcard.mhra.gov.uk.

Can Almus Constipation Relief Interact With Other Medicines?

Yes, bisacodyl can interact with certain other medicines and foods. Taking it within one hour of antacids or milk can dissolve the enteric coating too early, causing stomach irritation and reducing the medicine's effectiveness. If you are taking diuretics (water tablets) or corticosteroids (steroid medicines), the combination may increase the risk of low potassium levels in the blood. Always tell your pharmacist about all medicines, supplements, and herbal remedies you are currently taking before starting this product.

If you are concerned about any side effects, contact your pharmacist or GP immediately.
