Warnings

For adults and children 12 years of age and older who have acute or chronic diarrhea, the recommended dose of Imodium (Loperamide) is a starting dose of 4 mg, followed by a 2 mg dose after each loose bowel movement (or bout of diarrhea). Do not exceed 16 mg per day. For chronic diarrhea, once the optimal daily dose has been established, this dose can be given as a single daily dose or in divided doses.

Regular tablets should be taken with liquids. The quick-dissolve tablets can be taken without liquids. Imodium (Loperamide) tablets are not suitable for children under the age of 6 years old.

Children 6 to 12 years of age (10 kg to 20 kg) can use Imodium (Loperamide) for acute or chronic diarrhea if recommended by a doctor. For children 6 to 8 years old (or weighing 20 kg to 30 kg) the recommended dose for the first day is 2 mg twice daily. For children 8 to 12 years of age who weigh over 30 kg, the recommended dose for the first day is 2 mg 3 times daily. If the diarrhea continues, then the medication is given only after a loose bowel movement, and the amount to be given depends on the weight of the child. Contact your doctor or pharmacist for the recommended amount.

For children 2 to 5 years old (or weighing 10 kg to 20 kg) the recommended dose for the first day is 1 mg 3 times daily.

For liquid forms of Imodium (Loperamide), use a syringe to measure each dose as this gives a more accurate measurement than household teaspoons.

Stop using Imodium (Loperamide) if you have a solid or hard stool or if you go for 24 hours without a bowel movement. If you have acute (not chronic) diarrhea, see your doctor if it has not improved within 48 hours.

Many things can affect the dose of medication that a person needs, such as body weight, other medical conditions, and other medications. If your doctor has recommended a dose different from the ones listed here, do not change the way that you are taking the medication without consulting your doctor.

It is important to use Imodium (Loperamide) exactly as prescribed by your doctor. If you miss a dose, take it as soon as possible and continue with the recommended dosing schedule (after each loose bowel movement). If it is almost time for your next dose, skip the missed dose and continue with the recommended dosing schedule. Do not take a double dose to make up for a missed one. If you are not sure what to do after missing a dose, contact your doctor or pharmacist for advice.

Store Imodium (Loperamide) at room temperature, protect it from light and moisture, and keep it out of the reach of children.

Do not dispose of medications in wastewater (e.g. down the sink or in the toilet) or in household garbage. Ask your pharmacist how to dispose of medications that are no longer needed or have expired.

If you are taking any of these medications, speak with your doctor or pharmacist. Depending on your specific circumstances, your doctor may want you to:

stop taking one of the medications,
change one of the medications to another,
change how you are taking one or both of the medications, or
leave everything as is.

An interaction between two medications does not always mean that you must stop taking one of them. Speak to your doctor about how any drug interactions are being managed or should be managed.

Medications other than those listed above may interact with Imodium (Loperamide). Tell your doctor or prescriber about all prescription, over-the-counter (non-prescription), and herbal medications you are taking. Also tell them about any supplements you take. Since caffeine, alcohol, the Nicotine from cigarettes, or street drugs can affect the action of many medications, you should let your prescriber know if you use them.

Before you begin using a medication, be sure to inform your doctor of any medical conditions or Allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use Imodium (Loperamide).

Acquired immune deficiency syndrome (AIDS): People with AIDS should stop taking Imodium (Loperamide) and contact their doctor if they experience abdominal swelling or distention.

Constipation: If you develop constipation, stop taking Imodium (Loperamide) and contact your doctor.

Drowsiness or dizziness: Imodium (Loperamide) may cause drowsiness or dizziness. Do not drive or operate machinery until you know how Imodium (Loperamide) affects you.

Fluids and electrolytes: The loss of fluids and electrolytes (e.g., chloride, sodium) can occur if you have diarrhea. Imodium (Loperamide) helps with the symptoms of diarrhea but will not correct any fluid or electrolyte problems caused by diarrhea. Talk to your doctor or pharmacist about whether you need fluid and electrolyte replacement, also referred to as oral rehydration therapy.

Improvement in diarrhea: If your diarrhea has not improved after 48 hours of treatment with Imodium (Loperamide), stop taking it and contact your doctor.

Liver function: Liver disease or reduced liver function may cause Imodium (Loperamide) to build up in the body, causing side effects. If you have liver problems, discuss with your doctor how Imodium (Loperamide) may affect your medical condition, how your medical condition may affect the dosing and effectiveness of Imodium (Loperamide), and whether any special monitoring is needed.

Medical conditions: Imodium (Loperamide) should not be used by people with intestinal infections such as dysentery, which is often associated with severe diarrhea, fever, and blood in the stool, and other infections of the gut. A more serious problem of the bowel may develop if Imodium (Loperamide) is used by some people with acute ulcerative colitis or a serious form of diarrhea associated with antibiotic use.

Pregnancy: Imodium (Loperamide) should not be used during pregnancy unless the benefits outweigh the risks. If you become pregnant while taking Imodium (Loperamide), contact your doctor immediately.

Breast-feeding: Imodium (Loperamide) passes into breast milk. If you are a breast-feeding mother and are taking Imodium (Loperamide), it may affect your baby. Talk to your doctor about whether you should continue breast-feeding.

Children: Imodium (Loperamide) is not recommended for use in children under the age of 12 except on the advice of a physician. Imodium (Loperamide) should not be given to children under 6 years of age without medical prescription and supervision. Imodium (Loperamide) tablets are not suitable for children under 6 years of age. Imodium (Loperamide) should not be used for children under 2 years of age.
