Imodium (Loperamide Hydrochloride)

    Imodium (Loperamide Hydrochloride) Dosage and Side Effects

    Imodium works by slowing down the movement of the gut. This decreases the number of bowel movements and makes stool less watery.

    Warnings and Precautions

    Children younger than age 6 should not use Imodium unless directed by their doctor. This medicine should never be used in infants younger than 24 months.

    It may take up to 48 hours for your symptoms to improve.

    Call your doctor if your symptoms do not improve within two days of taking Imodium (10 days for chronic diarrhea), or if you develop bloody stools or a fever.

    Imodium is usually taken immediately after each loose bowel movement, though it's sometimes taken on a schedule for chronic diarrhea.

    Dosage is based on your condition and response to treatment. In children, dosage is also based on age and weight.

    Take your dosage of Imodium exactly as directed on the packaging or by your doctor.

    Adults should not use more than 8 milligrams (mg) in a 24-hour period if self-treating or 16 mg if under a doctor's supervision.

    If you are taking the chewable tablet form of Imodium, you should take it on an empty stomach. The tablets should be chewed completely before swallowing.

    If you are taking the dissolving tablets, you should dry your hands before opening the pack to remove a tablet. Place the tablet on the tongue and allow it to dissolve completely, and then swallow.

    Do not crush, split, or break the tablet. Do not remove the tablet from the pack until right before taking it. You do not need to take water with this form of the medication.

    If you are taking the oral suspension (liquid) form of Imodium, shake it well before you measure a dose. You should measure the liquid with a special dose measuring spoon or medicine cup.
