What are Imodium Dual Action Relief Tablets? 

Imodium Dual Action Relief Tablets are a treatment for sudden, short-lived attacks of diarrhoea using the active ingredient loperamide hydrochloride. These tablets also include simeticone to reduce excessive gas in the stomach, helping to relieve symptoms of bloating, trapped wind and painful cramps. 

What is the recommended dosage?

Always take Imodium Dual Action Relief Tablets exactly as described in the patient information leaflet or as your doctor / Chemist4U pharmacist has told you. For adults over 18 years old: Swallow two tablets initially, followed by one tablet after each loose bowel movement.

For children and young adults aged 12-18 years old: Swallow one tablet initially, followed by one tablet after each loose bowel movement. Do not take more than 4 tablets in any 24 hour period. Do not take for more than 48 hours - consult a doctor if your symptoms persist for more than 48 hours. 

How does loperamide hydrochloride and simeticone relieve diarrhoea? 

These tablets contain 2 mg of the active ingredient loperamide hydrochloride. This helps to reduce diarrhoea by slowing down your overactive bowel, helping your body to absorb fluid much more effectively. Imodium Dual Action Relief Tablets also contain 125 mg of simeticone, an anti-foaming agent that works to relieve bloating and stomach cramps by breaking up the excess gas in the bowel. 

What causes diarrhoea? 

Diarrhoea usually happens when fluid isn’t being absorbed from the contents of your bowel, or when extra fluid leaks into your bowel, causing loose or watery stools. There are many possible causes of diarrhoea:

  • A food intolerance

  • A food allergy

  • Food poisoning

  • Irritable bowel syndrome (IBS)

  • A viral infection, such as norovirus

  • A bacterial infection, such as E.coli

  • A reaction to a medication

  • A bowel or intestinal disease

  • Coeliac disease

Whilst unpleasant and uncomfortable, diarrhoea isn’t usually anything to worry about - it’s fairly common and improves after a couple of days in most cases.

What causes cramps, bloating and trapped wind? 

Stomach infections and bowel disorders, such as IBS, can also cause bloating. This happens when excess gas builds up in your gastrointestinal tract, resulting in an uncomfortable ‘full’ feeling. Symptoms related to excess gas include: 

  • A bloated stomach

  • Abdominal pain

  • Excessive flatulence or burping

  • Rumbling noises in your stomach

  • Stomach cramps

What is IBS?

Irritable bowel syndrome (IBS) is a condition that affects the digestive system, and it is quite common. You may experience symptoms varying from stomach cramps, bloating, gas, diarrhoea and constipation. Your symptoms may come and go, last for a period of time, or you may find that certain things trigger a flare-up.

What causes IBS?

The exact cause of IBS isn’t yet known, but there are some factors that are common in people with the condition. If you’ve got an abnormality in your digestive system, it may cause discomfort when releasing gas or stool. Your brain won’t send the accurate signals to your intestines that can result in your body overreacting to the digestive process, causing discomfort, constipation and diarrhoea.

You’re more prone to developing IBS if you’ve had a serious bout of diarrhoea caused by an infection, or if you’ve got a lot of bacteria harbouring in the intestines. Stressful situations can also be a trigger for IBS in certain people, especially if it occurred during childhood.

Are Imodium Dual Action Relief Tablets suitable for children? 

Imodium Dual Action Relief Tablets are not suitable for children under 12. Speak to a Chemist4U pharmacist for suitable alternatives for your child if they are suffering from diarrhoea, or take a look at our range of alternative diarrhoea relief products

Are Imodium Dual Action Relief Tablets suitable for pregnant and breastfeeding women? 

Do not take Imodium Dual Action Relief Tablets if you are breastfeeding, as small amounts may get into your milk. Speak to your doctor or Chemist4U pharmacist for suitable alternatives. If you are pregnant or breastfeeding, think you may be pregnant or are planning to have a baby, you must ask your doctor or Chemist4U pharmacist for advice before taking any new medicine. 

Does loperamide hydrochloride cause drowsiness? 

Yes, there is a chance that loperamide tablets can make you feel tired, sleepy or dizzy. If you are affected by these symptoms you should not drive or operate machinery.

When should this product not be used? 

Imodium Dual Action Relief Tablets may be unsuitable for certain people. Do not take these tablets if you are allergic to loperamide hydrochloride, simeticone or any of the other listed ingredients. Do not take these tablets if:

  • You have ever had a severe allergic reaction to any of the ingredients

  • You are suffering from a flare up of an inflammatory bowel disorder, such as ulcerative colitis

  • You are constipated, or your stomach appears swollen

  • You have acute dysentery, an intestinal infection that can cause blood in your stools and a high temperature

Talk to your doctor or Chemist4U pharmacist before taking this medicine if you suffer from liver disease, AIDS, or if your diarrhoea is persistent or severe. You should also seek medical advice before taking these tablets if you also take one of the following medicines:

  • Quinidine (used to treat abnormal heart rhythms or malaria)

  • Gemfibrozil (used to treat high cholesterol)

  • Desmopressin (used to control thirst and urine production in patients with diabetes insipidus)
