Patient Reviews: How Imodium Syrup SF Has Made a Difference

What is Imodium Syrup used for?

Imodium Syrup SF is an antidiarrhoeal oral solution for treating acute or chronic diarrhoea in adults. If you have trouble taking loperamide tablets, then Imodium syrup may be more suitable.

Imodium liquid is sugar-free and flavoured with raspberry and redcurrant flavourings. It is available in 100ml bottles, which yields approximately 10x 5ml doses.

Each pack of Imodium syrup comes with a plastic measuring cup to measure your dose correctly.

While Imodium tablets are available over the counter, Imodium syrup is only available on prescription.

With Prescription Doctor, you can order Imodium syrup online from a UK registered pharmacy. We offer a fast and discreet next-day delivery on orders approved before 3pm on weekdays.

What causes diarrhoea?

Diarrhoea is the passing of loose or watery stools more regularly than normal. It usually happens when your bowels are unable to absorb fluid back into your body properly, causing excessive water to come out with your stool.

Certain factors, such as bacteria or viral infections, food intolerances or diet can interfere with the bowel movements in some people, causing symptoms such as diarrhoea, among other conditions.

Why is it important to treat diarrhoea?

Diarrhoea causes the body to lose fluids, which can result in dehydration. Symptoms of dehydration can include:

  • Dizziness
  • Dry mouth
  • Dry skin
  • Fainting
  • Faster breathing
  • Headaches
  • Increased heartbeat
  • Muscle cramps
  • Sunken eyes

Treating diarrhoea can greatly reduce the risk of experiencing dehydration.

While taking Imodium Syrup, you must keep hydrated by drinking of plenty of water. Imodium syrup itself will not rehydrate you. 

Avoid drinking alcohol or caffeinated beverages while treating diarrhoea, as these can make your symptoms worse. Stick to water or fruit juice.

How does Imodium Syrup SF Work?

Imodium Syrup contains the active ingredient loperamide hydrochloride. Loperamide is a type of medicine which works against certain receptors in the bowels in order to decrease the tone of the muscles in the intestinal wall.

This action works to slow down the movements of the bowel, allowing the body to absorb water and thicken your stools.

How long does Imodium syrup take to work?

Loperamide, the active ingredient of Imodium syrup, starts working within 1 hour of taking it.

It may take a few days of taking Imodium before you notice an improvement in your condition.

How long does the effect of Imodium Syrup last?

The effect of Imodium Syrup should last between 8 and 12 hours. If taken in the morning, Imodium Syrup should provide all-day relief from diarrhoea.

Imodium Syrup only treats the diarrhoea symptoms and does not replenish the body with water or salts, which are typically lost during several episodes of diarrhoea. It is important to drink more fluids than normal when treating diarrhoea with loperamide.

How do I use Imodium Syrup SF?

Follow your physician's instructions carefully when you take Imodium Syrup SF.

Imodium Syrup SF comes with a measuring cup with a 5 ml line.

Set the measuring cup on a stable surface with the arrow pointing upward.

Pour the designated amount of solution into the cup, stopping when the fluid reaches the appropriate measuring line. For example, if your doctor says to take a 5 ml dose, stop pouring when the fluid line reaches the 5 ml mark on the cup.

Do not use a kitchen spoon, as this can lead you to taking the wrong amount of Imodium. Use the measuring cup provided.

The amount you take is related to whether the diarrhoea attack is sudden (acute) or it comes and goes over a period of time (chronic). For this reason, you must take Imodium as prescribed by your doctor.

Typical doses are:

  • For an adult with acute diarrhoea - four 5 ml portions at once for the initial dose. Take an additional two 5 ml doses after each diarrhoea episode until it stops.
  • Adults with chronic diarrhoea - Unless otherwise directed by your doctor, take four to eight 5 ml doses throughout the day.

Do not take more than 16x 5ml doses in one day.

Your diarrhoea symptoms should improve within two days after the first dose. If not, stop taking Imodium Syrup and contact your doctor.

What should I do if I forget to take a dose of Imodium Syrup?

If you forget to take Imodium Syrup, take the dose as soon as you remember. If it is almost time for your next dose, skip the missed dose of Imodium Syrup.

Do not take more Imodium Syrup to make up for a missed dose.

What should I do if I take too much Imodium Syrup?

There have been incidents of serious heart problems after taking too much loperamide, which is the active ingredient in Imodium Syrup SF.

If you take too much Imodium Syrup, seek help at the hospital casualty department, especially if you feel like your heart is racing, have slow breathing, or become dizzy.

If you are unsure how much Imodium to take, ask your doctor or speak to a pharmacist.
