WARNINGS AND PRECAUTIONS

KEEP THIS AND ALL DRUGS OUT OF THE REACH OF CHILDREN

BEFORE you use IMODIUM® Complete talk to your doctor or pharmacist if you:

  • have mucus in the stool;
  • are pregnant or nursing a baby (IMODIUM® Complete is not recommended for nursing mothers because small amounts of loperamide can end up in your milk);

  • have meningitis or liver disease, as you may need medical supervision while taking IMODIUM® Complete;
  • have a history of abnormal heart rhythm (e.g., Brugada syndrome).

Dosage warning:

Taking more than directed can cause serious heart problems or death.

STOP USE and see your doctor or pharmacist if:

  • Diarrhea gets worse, lasts longer than 48 hours or you get any unusual symptoms;
  • You are infected with HIV and you have any signs of abdominal swelling or bulging.

Although IMODIUM® Complete stops diarrhea, it will not treat the cause of it. Whenever possible, the cause of diarrhea should also be treated.

Tiredness, dizziness, or drowsiness may occur in the setting of diarrheal symptoms treated with loperamide. Therefore, it is advisable to use caution when driving a car or operating machinery.

INTERACTIONS WITH THIS MEDICATION

Always tell your doctor or pharmacist

  • if you are using other drugs including herbal medicines because some drugs should not be taken together
  • if you are taking drugs that slow down the action of the stomach and intestines (for example, some antidepressants and cold and allergy medication), because these can make the effect of IMODIUM® Complete too strong.
  • if you are taking sedating medications.

In particular, tell your doctor or pharmacist if you are taking any of the following:

  • ritonavir (used to treat HIV)
  • quinidine (used to treat abnormal heart rhythms)
  • oral desmopressin (used to treat excessive urination)
  • itraconazole or ketoconazole (used to treat fungal infections)
  • gemfibrozil (used to lower cholesterol)

PROPER USE OF THIS MEDICATION

IMODIUM® Complete should be taken by mouth and can be taken at any time of day. The caplets should be taken with a full (250 mL) glass of water.

When you have diarrhea,

  • you will lose a lot of fluids. Therefore, drink plenty of clear fluids, water, unsweetened juices or clear soups.
  • Take the caplets only on an empty stomach (1 hour before or 2 hours after a meal).

  • do not drink alcohol or milk and avoid fruit, green vegetables and spicy or fatty foods. These items tend to aggravate diarrhea.

Usual dose:

Adults (12 years and older): Swallow 2 caplets initially and 1 caplet every time you have a loose bowel movement, to a maximum of 4 caplets per day. Do not exceed the recommended dose. Stop use if you have a solid or hard stool or if you go for 24 hours without a bowel movement.

IMODIUM® Complete is not recommended for children under 12 years except on the advice of a doctor.

Overdose:

In case of drug overdose, contact a health care practitioner, hospital emergency department or regional Poison Control Centre immediately, even if there are no symptoms.

SIDE EFFECTS AND WHAT TO DO ABOUT THEM

IMODIUM® Complete is usually well tolerated and few undesired effects are likely when it is taken as directed.

Constipation may occur. If so, stop IMODIUM® Complete and if these effects are severe, consult your doctor.

Oversensitivity to IMODIUM® Complete is rare. It can be recognized, for instance, by skin rash or itching. If any of these signs occur, see your doctor.

The following complaints sometimes occur, but they may be due to the diarrhea itself: nausea and vomiting, tiredness, dizziness or drowsiness, dry mouth and flatulence.
