1. What Dimor is and what it is used for

Dimor normalizes bowel movements, counteracts fluid loss, and increases the ability to hold stools.

Dimor is used in temporary ( acute ) diarrhea. Dimor can also be prescribed by a doctor for other uses such as prolonged ( chronic ) diarrhea and in the “bag on the stomach” ( stoma ) after certain gastrointestinal surgeries or in case of inability to hold the stool (feces incontinence).

If you bought Dimor without a prescription, you must talk to a doctor if you do not feel better or if you feel worse after 2 days.

2. What you need to know before you take Dimor

Do not take Dimor

  • if you are allergic to loperamide or any of the other ingredients of this medicine (listed in section 6),
  • to children under 12 years,
  • if you have a high fever or blood in the stool ( acute dysentery),
  • in acute symptoms of inflammation of the colon ( ulcerative colitis ),
  • in inflammation of the small and large intestine caused by invasive bacteria, including Salmonella, Shigella, and Campylobacter,
  • in inflammation-like conditions of the colon caused by antibiotics(pseudomembranous colitis ),
  • if the passage of food through the intestine is already slow, for example in case of constipation or distended abdomen.

Warnings and cautions

– Do not take this medicine for anything other than its intended use (see section 1) and never take more than the recommended dose (see section 3). Severe heart problems (with symptoms such as rapid or irregular heartbeat) have been reported in patients taking too much loperamide, the active substance in Dimor.

– Treatment with Dimor relieves symptoms but does not cure the cause. Before long-term treatment, the underlying disease must therefore be investigated and treatment against this put in the first place.

– If temporary diarrhea has not stopped after 2 days of treatment, discontinue treatment and consult a doctor.

– If you have impaired liver function, you should consult a doctor before starting treatment with Dimor.

– In diarrhea, the body loses more fluid and salts than normal. Children, in particular, are susceptible to dehydration. Replace fluid loss by drinking plenty of fluids. Do not give Dimor to children under 12 years of age without a doctor’s prescription.

– If you have AIDS and your stomach swells, stop taking the tablets immediately and contact a doctor.


Dimor should not be given to children under 12 years of age.
