1. What is Reasec and what is it used for

The active substances of Reasec are: diphenoxylate (in the form of diphenoxylate hydrochloride) and atropine (in the form of atropine sulfate). The medicine reduces intestinal motility and has a strong constipating effect.
Indications for use:

• symptomatic treatment of acute and chronic diarrhea of various origins,
• reduction of fluid stool after ileostomy (surgical diversion of a portion of the small intestine to the abdominal surface allowing for the elimination of intestinal contents) and colostomy (surgical diversion of a portion of the large intestine to the abdominal surface allowing for the elimination of intestinal contents).

2. Important information before taking Reasec

When not to take Reasec:

• when it is possible to treat the cause of diarrhea, it should be done. Reasec is intended only for symptomatic treatment of diarrhea;
• if the patient is allergic to diphenoxylate hydrochloride and/or atropine sulfate or any of the other ingredients of this medicine (listed in section 6);
• in children under 4 years of age;
• in the treatment of diarrhea caused by bacteria that produce enterotoxins (e.g. toxigenic Escherichia coli, Salmonella and Shigella), which may be accompanied by high fever and blood in the stool;
• in the treatment of the acute phase of ulcerative colitis or pseudomembranous colitis caused by antibiotics;
• in cases of severe liver cirrhosis;
• in cases of acute and cholestatic hepatitis with jaundice (yellowing of the skin and eyes), itching of the skin;
• in the treatment of mechanical jaundice;
• if the patient has glaucoma with a narrow angle of vision;
• if the patient has prostate disease;
• in cases of myasthenia (a disease characterized by weakness and fatigue of skeletal muscles);
• in patients with accelerated heart rate;
• in children with asthma;
• in patients with megacolon (a disease that causes hypertrophy and dilation of the colon due to the accumulation of intestinal contents);
• in patients with pyloric stenosis;
• if the patient has intestinal obstruction or constipation;
• if the patient is taking other medicines that reduce intestinal motility.

Warnings and precautions

Before starting to take Reasec, discuss it with your doctor or pharmacist.
In every case where possible, the cause of diarrhea should be treated. This medicine does not remove the cause of diarrhea and is intended only for symptomatic treatment of diarrhea.
In patients with diarrhea, especially in children, there may be a loss of fluids and electrolytes. In such cases, the most important thing is to replenish fluids and electrolytes.
In cases of severe dehydration or electrolyte imbalance, the administration of Reasec should be discontinued until proper fluid and electrolyte replenishment is started, as the reduction of intestinal motility may cause fluid retention in the intestines, exacerbating dehydration and electrolyte imbalance.
If there is no improvement in acute diarrhea within 48 hours, the use of the medicine should be discontinued.
The use of Reasec should be discontinued immediately if abdominal distension or constipation occurs.
In cases of liver function disorders, patients should be under medical supervision, due to the possible toxic effect of Reasec on the nervous system, caused by slowed metabolism of the medicine.
During the use of the recommended doses of Reasec, side effects of atropine may occur. These include: accelerated heart rate, dryness of the mouth, dryness of the skin, and nausea. This is especially true for children. The doctor or pharmacist should be informed about this (see section 4).
Diphenoxylate belongs to the group of opioids. Cases of dependence on Reasec have been reported (with the use of very high doses, over 125 tablets per day). Therefore, special caution should be exercised when using Reasec in patients with a history of drug dependence. The addition of atropine is intended to prevent cases of drug abuse.

Children and adolescents

The most effective way to treat diarrhea in children is to replenish fluids and electrolytes.
Reasec can only be used in children over 4 years of age, under medical supervision.
The dosage prescribed by the doctor should be strictly followed, and until the symptoms disappear (e.g. based on stool assessment), constant medical supervision is necessary.
Young children may be particularly sensitive to the active substances of the medicine. Administering doses higher than those prescribed by the doctor can be dangerous, especially in children.

Reasec and other medicines

Tell your doctor or pharmacist about all medicines you are taking, or have recently taken, and about medicines you plan to take.
Do not take alcohol and other medicines that affect the central nervous system (anxiolytics, sedatives, and narcotics) while taking Reasec, as they may enhance each other's effects, drowsiness, and respiratory depression may occur.
Reasec tablets may cause slower breakdown of some other medicines in the liver, resulting in prolonged or enhanced effects.
The above interactions apply to medicines taken previously, as well as those that will be taken in the near future. In case of doubt, whether any of the above situations apply to you, consult your doctor or pharmacist before taking Reasec.
