Loperamide hydrochloride
This medicine should always be taken exactly as described in this patient leaflet or as directed by a doctor or pharmacist.
Loperamide is an oral anti-diarrheal medicine.
It reduces intestinal peristalsis, prolongs the transit time of food through the intestines. Loperamide
increases the resting pressure of the anal sphincter, while reducing the immediate need for bowel movement.
Imodium Instant is indicated for the symptomatic treatment of acute and chronic diarrhea in adults and children over 6 years old.
In patients with an ileostomy, Imodium Instant may be used to reduce the number and volume of stools and increase their consistency.
The medicine can also be used for the symptomatic treatment of acute episodes of diarrhea associated with irritable bowel syndrome in adults (from 18 years old) after prior diagnosis of the disease by a doctor with the reservations mentioned in "Warnings and precautions" in section 2.
Treatment of diarrhea with Imodium Instant is only symptomatic. In any case where it is possible to determine the cause of diarrhea, when justified (or indicated), the doctor will recommend appropriate treatment.
In patients with diarrhea, especially in children, dehydration and excessive loss of electrolytes may occur. Therefore, during diarrhea, it is necessary to take more fluids than usual to supplement these deficiencies.
If after administration of the medicine in acute diarrhea, the symptoms do not disappear within 48 hours, the administration of Imodium Instant should be stopped and a doctor consulted.
Patients with AIDS taking Imodium Instant for diarrhea should immediately stop taking the medicine and consult a doctor if they experience early symptoms of abdominal distension. There have been reports of individual cases of toxic colonic dilation in patients with AIDS and concomitant infectious colitis caused by both viruses and bacteria, treated with loperamide hydrochloride.
Patients diagnosed with irritable bowel syndrome by a doctor before taking the medicine should discuss treatment with their doctor or pharmacist, especially if:
There have been reports of abuse and use of Imodium Instant not in accordance with its indications (see section 1) or in higher doses than recommended (see section 3). In patients taking too high doses of loperamide (the active substance of Imodium Instant), serious heart rhythm disturbances (including accelerated or irregular heart rhythm) have been noted.
Tell your doctor or pharmacist about all medicines you are currently taking or have recently taken and about medicines you plan to take.
It is especially important to inform your doctor or pharmacist about taking:
If you are pregnant or breastfeeding, think you may be pregnant, or plan to have a child, consult your doctor or pharmacist before taking this medicine.
The doctor should carefully weigh the expected benefits to the mother's health against the potential risk associated with the use of Imodium Instant by pregnant women, especially in the first trimester.
It is not recommended to take Imodium Instant during pregnancy and breastfeeding. Pregnant or breastfeeding women should therefore consult a doctor to determine the appropriate treatment.
During the treatment of diarrhea with loperamide, fatigue, dizziness, or drowsiness may occur, so caution should be exercised when driving vehicles or operating machines.
Aspartame is a source of phenylalanine. It may be harmful to patients with phenylketonuria. This is a rare genetic disorder in which phenylalanine accumulates in the body due to its improper excretion.
The medicine may rarely cause severe hypersensitivity reactions and bronchospasm.
If the patient has previously been diagnosed with intolerance to some sugars, they should consult their doctor before taking the medicine.
Benzyl alcohol may cause allergic reactions.
Patients with liver or kidney disease should consult their doctor before taking the medicine, as a large amount of benzyl alcohol may accumulate in their body and cause side effects (so-called metabolic acidosis).
The medicine contains less than 1 mmol (23 mg) of sodium per dose, which means the medicine is considered "sodium-free".
This medicine should always be taken exactly as described in this patient leaflet or as directed by a doctor or pharmacist. In case of doubt, consult a doctor or pharmacist.
Imodium Instant orally disintegrating tablet should be placed on the tongue, waited for it to dissolve, and swallowed with saliva. No liquid is needed to swallow.

Chronic diarrhea: initial dose - 2 tablets (4 mg) per day for adults and 1 tablet (2 mg) per day for children; this initial dose should be modified until 1 to 2 normal stools per day are achieved, which is usually achieved by taking a maintenance dose of 1 to 6 tablets (2 mg to 12 mg) per day.
The maximum dose in acute and chronic diarrhea - 8 tablets (16 mg) per day for adults and children; in children, the dose of the medicine must be adjusted according to body weight (3 tablets/20 kg body weight).
Do not take a dose higher than the maximum recommended dose.
Adults from 18 years old
Initial dose - 2 tablets (4 mg) per day, and then 1 tablet (2 mg) after each subsequent loose stool or as previously directed by a doctor. Imodium Instant can be taken for up to 2 weeks with recurrent episodes, but no longer than 48 hours with single episodes of diarrhea (see also "Warnings and precautions" in section 2).

Symptoms
In case of overdose, the following symptoms may occur: accelerated heart rate, irregular heart rhythm, changes in heart rhythm (these symptoms may have severe, life-threatening consequences), muscle stiffness, uncoordinated movements, drowsiness, difficulty urinating, shallow breathing, slow breathing, stupor, and intestinal obstruction (manifested by abdominal pain, vomiting, bloating, and constipation). In children, the reaction to taking large amounts of Imodium Instant is stronger than in adults.
Treatment
If a patient has taken too much Imodium Instant, they should immediately consult a doctor or go to the hospital.
If a child has taken too much medicine or any of the above symptoms occur, they should immediately consult a doctor.
The doctor will take appropriate actions, such as performing a control ECG and administering naloxone if necessary. Since the duration of action of loperamide is longer than that of naloxone (1 to 3 hours), it may be necessary to repeat the administration of naloxone. Therefore, the patient should remain under close supervision for at least 48 hours to detect any possible central nervous system depression.
