Loperamide Hydrochloride
Take this medicine always exactly as described in the package leaflet or as directed by your doctor or pharmacist.
Stoperan contains loperamide. It is an anti-diarrheal medicine. Stoperan slows down increased bowel movements and also increases water absorption. As a result, it slows down the passage of food through the intestines, reduces the frequency and number of bowel movements, and by reversing water absorption in the large intestine, changes the consistency of the stool. Stoperan is intended for use in adults and children over 6 years old.
Stoperan is indicated for the symptomatic treatment of acute and chronic diarrhea. If after 2 days there is no improvement or the patient feels worse, contact your doctor.

Caution should be exercised when taking Stoperan in bacterial diarrhea.
In patients with liver function disorders, the medicine should be used with caution due to the possibility of toxic effects on the central nervous system.
In patients with diarrhea, especially in children, dehydration and electrolyte deficiency may occur.
Therefore, during diarrhea, water and mineral salts should be supplemented.
The administration of the medicine should be discontinued in case of constipation, bloating, or developing intestinal obstruction.
In patients with fever and blood in the stool, before starting loperamide, the cause of diarrhea should be determined.
In patients with AIDS, treated with Stoperan for diarrhea, the administration of the medicine should be discontinued in case of early symptoms of abdominal distension. In patients with AIDS and concurrent infectious colitis caused by both viruses and bacteria, single cases of toxic megacolon have been reported during the use of loperamide.
This product should not be taken for purposes other than its intended use (see section 1) or in doses higher than recommended (see section 3). In patients taking too high doses of loperamide (the active substance of Stoperan), serious heart rhythm disorders (including accelerated or irregular heart rhythm) have been reported.
Stoperan is contraindicated in children under 6 years old.
Inform your doctor about all medicines you are currently taking or have recently taken, as well as any medicines you plan to take.
Concomitant administration of loperamide (16 mg in a single dose) with quinidine (a medicine used to treat heart rhythm disorders) or ritonavir (used to treat HIV infection), which are P-glycoprotein inhibitors, results in increased loperamide plasma concentrations. The clinical significance of these interactions is unknown.
It is recommended to take Stoperan with water.
Stoperan can be taken on an empty stomach or after a meal.
Stoperan taken in doses used to treat diarrhea practically does not penetrate the central nervous system, so the risk of interaction with alcohol is minimal.
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.
Before taking the medicine, consult your doctor.
During the treatment of diarrhea with loperamide, fatigue, dizziness, or drowsiness may occur.
Therefore, caution should be exercised when driving or operating machinery.
If you have been diagnosed with intolerance to some sugars, you should consult your doctor before taking the medicine.

If you feel that the effect of Stoperan is too strong or too weak, consult your doctor.
In case of overdose, constipation, intestinal obstruction, urinary retention, and symptoms of central nervous system depression (increased muscle tone, stupor, confusion, drowsiness, coordination disorders, miosis, apnea, respiratory depression) may occur. Children are more sensitive than adults to the occurrence of adverse effects of the medicine on the central nervous system.
If you have taken too much Stoperan, seek medical advice immediately. The following symptoms may occur: accelerated heart rate, irregular heart rhythm, changes in heart rhythm (these symptoms can have severe, life-threatening consequences), muscle stiffness, uncoordinated movements, drowsiness, difficulty urinating, and shallow breathing.
In children, the reaction to taking large amounts of Stoperan is stronger than in adults. If a child has taken too much Stoperan or any of the above symptoms occur, seek medical advice immediately.
In case of taking a higher dose of the medicine than recommended, seek medical advice immediately.
In case of overdose symptoms, the doctor may recommend the administration of naloxone. Since the duration of action of Stoperan is longer than that of naloxone (1 to 3 hours), repeated administration of naloxone may be necessary. Therefore, the patient should be under close medical supervision for at least 48 hours to detect any possible depression of the central nervous system.
Do not take a double dose to make up for a missed dose.
Stoperan is taken as needed, so after improvement, its use can be stopped.
In case of any further doubts about the use of this medicine, consult your doctor or pharmacist.
