How should I use Imodium
Use Imodium (Oral) exactly as directed on the label, or as prescribed by your doctor. Do not use in larger or smaller amounts or for longer than recommended.
Use exactly as directed on the label, or as prescribed by your doctor.
Loperamide is safe when used as directed. TAKING TOO MUCH LOPERAMIDE CAN CAUSE SERIOUS HEART PROBLEMS OR DEATH.
Always follow directions on the medicine label about giving loperamide to a child. A safe dose of loperamide is different for an adult than for a child. Doses in children are based on the child's age.
Take loperamide with a full glass of water. Diarrhea can cause your body to lose fluids and electrolytes. Drink plenty of liquids to keep from getting dehydrated.
The loperamide chewable tablet must be chewed before swallowing.
Shake the oral suspension (liquid) before you measure a dose. Use the dosing syringe provided, or use a medicine dose-measuring device (not a kitchen spoon).
Not all liquid forms of loperamide are the same strengths. Carefully follow all dosing instructions for the medicine you are using.
Store at room temperature away from moisture and heat. Do not allow the liquid medicine to freeze.
Stop taking loperamide and call your doctor if you still have diarrhea after 2 days of treatment, or if you also have stomach bloating.
Since loperamide is used when needed, it does not have a daily dosing schedule. Call your doctor if your symptoms do not improve after using this medicine.

Stop taking loperamide and call your doctor at once if you have:
- diarrhea that is watery or bloody;
