Imodium Instant Melts - 12
Melt in the mouth tablets, can stop diarrhoea in under 1 hour
How does it work?
Imodium capsules, syrup and instants all contain the active ingredient loperamide hydrochloride, which is a medicine used to treat diarrhoea. (NB. Loperamide is also available without a brand name, ie as the generic medicine.) Loperamide works by slowing the muscular contractions of the intestine and so is called an 'antimotility' medicine.
Loperamide works by acting on opioid receptors that are found in the muscle lining the walls of the intestines. By acting on these receptors, loperamide reduces the muscular contractions of the intestine (called peristalsis) that move food and faecal matter through the gut.
This reduces the speed at which the gut contents are pushed through the intestines, allowing more time for water and electrolytes to be reabsorbed from the gut contents back into the body. This results in firmer stools that are passed less frequently.
Loperamide can be bought without a prescription to treat acute (sudden and short-lived) episodes of watery diarrhoea in adults.
Loperamide can also be used to control flare-ups of chronic (long-term) diarrhoea, however it should only be used for this purpose on the advice of a doctor. It should only be used to treat diarrhoea associated with irritable bowel syndrome (IBS) after initial diagnosis of IBS by a doctor.
What is it used for?
When bought without a prescription Imodium can be used to treat:
- Acute diarrhoea in adults and children aged 12 years and over.
- Acute diarrhoea associated with irritable bowel syndrome (IBS) in adults aged 18 years and over, following initial diagnosis by a doctor.
Imodium can also be used to treat the following, but ONLY when prescribed by a doctor:
- Acute diarrhoea of any cause, including treating sudden worsening of long-term diarrhoea for periods of up to five days, in adults and children over eight years of age (capsules) and children over four years of age (syrup).
- Chronic (long-term) diarrhoea in adults.
- DON'T take this medicine and consult a doctor instead if any of the following apply to you: if your diarrhoea started either during or after taking a course of antibiotics; if the diarrhoea contains yellow or greenish mucus or blood; if you also have a fever.
- Do not exceed the recommended dose of this medicine, which will be stated in the product packaging or information leaflet supplied with the medicine.
- If you have bought Imodium without a prescription and your symptoms persist for more than 24 hours, you should consult a doctor.
- If you get any swelling of your stomach after taking this medicine don't take any further doses and consult your doctor.
- Acute diarrhoea makes you lose more fluids and salt than you usually would and can make you dehydrated. This medicine only treats the diarrhoea symptoms and so will not rehydrate you. You should ensure that you drink plenty of fluids, and you may also want to take an oral rehydration therapy, which is a soluble powder containing sugars and salts, to help rehydrate you. This is particularly important for frail and elderly people and children. Rehydration salts can be bought from pharmacies.
- If you are taking Imodium to control episodes of diarrhoea associated with irritable bowel syndrome diagnosed by your doctor, you should return to your doctor if the pattern of your symptoms changes. You should also return to your doctor if your symptoms continue for more than two weeks, or you need continuous treatment for more than two weeks.
