1. What is Lopestop and what is it used for

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

Lopestop is a medicine indicated for the symptomatic treatment of acute nonspecific diarrhea in adults and adolescents over 12 years of age.

You should consult a doctor if it worsens or does not improve after 2 days.

2. What you need to know before taking Lopestop

Do not take Lopestop:

  • If you are allergic to loperamide hydrochloride or any of the other components of this medicine (listed in section 6).
  • Do not administer to children under 2 years of age.
  • If blood appears in the stool or high fever (above 38°C).
  • If you have acute ulcerative colitis (inflammation of the intestine).
  • If you suffer from severe diarrhea (pseudomembranous colitis) after taking antibiotics.

  • If there is no improvement within 48 hours, discontinue treatment and consult your doctor.
  • You must discontinue treatment immediately if sudden constipation and/or abdominal distension or ileus (absence of intestinal movements) occurs.
  • Patients with AIDS being treated with Lopestop should discontinue treatment when the first symptoms of abdominal distension appear.
  • Patients 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 of diarrhea with Lopestop is only symptomatic, diarrhea should be treated from its cause, when possible.
  • Patients with liver problems should consult their doctor before taking this medicine.
  • Medicines that prolong intestinal transit time may induce dilation of the large intestine (toxic megacolon).
  • Do not take this medicine for a use other than indicated (see section 1).
  • Never take more than the indicated 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 of Lopestop.
