1. What is Diarfin and what is it used for

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

Diarfin is used for the symptomatic treatment of acute non-specific diarrhea in adults and children over 12 years of age.

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

Doctor consultation

Discuss your symptoms and treatment with a doctor online.

2. What you need to know before taking Diarfin

Do not take Diarfin

  • 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 been diagnosed with acute ulcerative colitis (inflammation of the intestine).
  • If you suffer from severe diarrhea (pseudomembranous colitis) after taking antibiotics.
  • If you suffer from diarrhea due to an infection caused by organisms such as Salmonella, Shigellaor Campylobacter.

Warnings and precautions

Consult your doctor or pharmacist before starting to take Diarfin.

  • If there is no improvement within 48 hours or if fever, constipation, or other symptoms such as abdominal swelling or paralytic ileus (absence of intestinal movements) appear, discontinue treatment and consult your doctor.
  • If you suffer from severe diarrhea, your body loses more fluids, sugars, and salts than usual, so you will need to replenish fluids by drinking more than usual. Dehydration is characterized by dry mouth, excessive thirst, decreased urine output, wrinkled skin, dizziness, and drowsiness. It is very important to prevent dehydration in children and elderly patients.
  • Patient with AIDS should discontinue treatment when the first symptoms of abdominal swelling appear.
  • If you have any liver or kidney disease or blood disorders, consult your doctor before taking this medicine.
  • Since the treatment of diarrhea with Diarfin is only symptomatic, diarrhea should be treated from its cause, when possible.
  • Do not take this medicine 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 of Diarfin.

Children and adolescents
