1. What is Loperan and what is it used for

Loperan is an antidiarrheal that reduces intestinal movements and secretions, resulting in a decrease in liquid stools.

Loperan is indicated for the symptomatic treatment of acute nonspecific diarrhea in adults and children over 12 years of age.

2. What you need to know before taking Loperan

  • If you are allergic to loperamide hydrochloride or any of the other components of this medication (listed in section 6).
  • If you have constipation or abdominal bloating.
  • If you have severe liver problems (severe hepatic insufficiency).
  • Do not administer to children under 2 years of age.
  • If blood appears in stools or you have a high fever (above 38°C).
  • If you have ulcerative colitis (inflammation of the intestine)
  • If you have severe diarrhea after taking antibiotics (pseudomembranous colitis).
  • If you have diarrhea due to an infection caused by organisms such as Salmonella, Shigella, or Campylobacter.

Warnings and precautions

  • Do not take this medication for a use other than indicated (see section 1) and never take more than the recommended amount (see section 3). Serious heart problems (whose symptoms include rapid or irregular heartbeats) have been reported in patients who have taken an excessive amount of loperamide, the active ingredient in Loperan.
  • If you do not observe improvement within 48 hours or if a fever appears, discontinue treatment and consult your doctor.
  • If you have liver problems, you should consult your doctor before taking Loperan.
  • Pre-filled transparent syringe with yellow liquid and gray needle connected ready for injection Patients with AIDS who are being treated with Loperan for diarrhea should discontinue treatment when the first symptoms of abdominal bloating or distension (megacolon) appear.
  • Patient with diarrhea should drink plenty of fluids to avoid dehydration, which is manifested by: dry mouth, excessive thirst, decreased urine output, wrinkled skin, dizziness, and drowsiness. This is especially important in children and the elderly.
  • Treatment should be suspended rapidly if constipation, abdominal distension (bloating), or ileus (absence of intestinal movements) occurs.
  • Treatment of diarrhea with loperamide is only symptomatic, so the diarrhea should be treated based on its cause.

Children and adolescents

Do not administer this medication to children under 12 years of age without medical prescription and supervision.

Taking Loperan with other medications

Inform your doctor or pharmacist if you are using, have recently used, or may need to use any other medication.

In particular, inform them if you are taking any of the following medications:

  • Ritonavir, saquinavir (used to treat HIV).
  • Quinidine (used to treat abnormal heart rhythms).
  • Desmopressin oral (used to treat central diabetes insipidus and nocturnal urinary incontinence in children).
  • Itraconazole or ketoconazole (used to treat fungal infections).
  • Gemfibrozil (used to lower cholesterol).
  • St. John's Wort (used to improve mood).
  • Valerian (used to treat mild anxiety).
  • Opioid analgesics (used to treat intense pain) as it may increase the risk of severe constipation and central nervous system depression (e.g., drowsiness or decreased consciousness).
  • Broad-spectrum antibiotics, as Loperan may worsen or prolong antibiotic-induced diarrhea.

It may potentiate the action of drugs with similar properties.
