Treatment Information

Table of contents:

What is Imodium?

While Imodium Syrup, Classic capsules, and the orodispersible Instant Melts contain an anti-motility agent called loperamide, Imodium Plus Comfort combines loperamide with an anti-flatulent agent called Simeticone.

You can buy Imodium capsules and tablets over the counter at most pharmacies and some supermarkets. However, Imodium Syrup is only available on prescription.

Imodium typically relieves diarrhoea in 2 days.

How does Imodium work?

Imodium contains loperamide, a compound that belongs to a group of medicines called anti-motility agents. This class of medicine slows down the movement of the bowel.

Your intestines are the final stage of the digestive tract. They play a vital role in extracting remaining nutrients, vitamins, and water from the digested food as it passes through the intestines. Small finger-like protrusions absorb nutrients and pass them directly into the bloodstream for the body to utilise.

Surrounding the intestines are smooth muscles. These muscles contract in waves to push the digested food, known as chyme, through the intestines. As the faecal matter is pushed through, water and nutrients are absorbed, and the poo becomes drier and firmer.

However, if the stools are pushed through the intestines too quickly, such as during an illness or due to an intolerance, the intestines are unable to extract as much water as they usually would. This results in more water being passed with the stools and ultimately results in diarrhoea.

Loperamide slows down the contractions of the muscles that propel stools through the intestines, allowing the intestines to absorb water more effectively. As a result, the stools become firmer.

Simeticone, found in Imodium Plus Comfort, is an antiflatulent. It helps small gas bubbles in the gut to join together, allowing them to pass through the body more easily and relieve trapped wind.

How do I take Imodium?

How you take Imodium depends on whether it is in capsule, tablet, or orodispersible form.

How Long Does it Take for Imodium to Work?

If you’re looking for a reliable and effective treatment for diarrhoea, you may have previously tried Imodium syrup. However, Imodium syrup is no longer available. Instead, an alternative is available in the form of Imodium capsules.Also known as loperamide, Imodium capsules are a common go-to treatment for diarrhoea, particularly sudden diarrhoea. When the time comes for Imodium, you’ll probably need it to work as quickly as possible. If you’re wondering how long it takes to feel the benefits, read on.Diarrhoea is a very common condition, and while most cases are mild, it can sometimes require medical attention. The most common cause is gastroenteritis. People often suffer diarrhoea when travelling abroad when they are exposed to food they are not used to eating. It can also be the result of stress, allergies, medication, or irritable bowel syndrome (IBS).What causes diarrhoea?Diarrhoea occurs when the cells in your small intestine or colon become irritated, which increases the movements in your intestines. This causes fluids and salts to be passed through the colon too quickly for absorption. As more fluid stays in your intestine as the food travels through, it results in watery, more frequent bowel movements.Imodium capsules contain the active ingredient loperamide, which slows down the movement of digested food through the colon. This helps your body absorb more water through your intestines, making your stool firmer and reducing the frequency of trips to the toilet.How long does Imodium take to work?Imodium capsules can improve your symptoms within an hour and remain effective for several hours after you take them.Depending on the cause of your diarrhoea, it may take 2 to 4 days for your diarrhoea to subside. In most cases, Imodium capsules can bring relief and restore your gut’s normal rhythm within 48 hours.{add_product_block(282)}What to look out for when buying Imodium?Imodium comes in various forms, including:Tablets and hard or soft capsules. You can usually take these with a glass of water, just as you would any other medicine.Tablets that melt on your tongue. Often called ‘Imodium Instants’ or ‘Imodium Instant Melts’, you should put it on your tongue and allow it to slowly dissolve. It is then acceptable to swallow the rest with a drink.If you are unsure as to which form is right for you, talk to a pharmacist about your symptoms, and they should be able to help you make the right decision. You may have previously used Imodium syrup to relieve diarrhoea symptoms, but this is no longer available. Instead, you may find Imodium capsules to be a suitable alternative.Some supermarkets and pharmacies sell in-house brands of loperamide capsules, commonly referred to as "anti-diarrhoeal" or "diarrhoea relief" on the label.Some products even contain the term "IBS" to tell customers that they can be used for diarrhoea caused by irritable bowel syndrome. However, products without IBS in their name can also be used by people with IBS.According to the NHS, here are some things to think about when taking Imodium:For adults, the usual starting dose of Imodium is 2 capsules, which should be taken immediately when symptoms start.You should then take 1 capsule after each bout of diarrhoea.You shouldn’t take any more than 6 Imodium capsules if you have bought it over the counter from a supermarket or pharmacy. Or 8 capsules if you have a prescription for Imodium capsules.As soon as your symptoms settle, stop taking Imodium capsules. You shouldn’t take them for longer than 48 hours without talking to a clinician. For chronic conditions like IBS, follow your doctor’s advice.Diarrhoea can dehydrate you quickly, so remember to stay hydrated.Remember: Imodium is a short-term solutionTry not to make a habit of taking Imodium capsules, as they won't address the root cause of your sudden bowel disturbances. Once you have gained control of your bowel movements, identify the reason for your diarrhoea and address it directly.Do not take Imodium for more than 48 hours without consulting a doctor, especially if you initially purchased it to treat short-term diarrhoea. Most cases of diarrhoea will improve within a week. Talk to your doctor if your symptoms of diarrhoea haven't improved in 7 days. After this time, it's essential to begin treating the effects of diarrhoea, such as dehydration.Try not to exceed the recommended dose.
