Loperamide: An In-Depth Medication Guide for Patients

Imodium (Loperamide)

Loperamide, available under the popular brand name Imodium, is a medication used to treat diarrhea.

Pharmacologic Category

Loperamide is a part of the class of drugs known as peripherally acting anti-diarrheal agents. Other medications in this category include diphenoxylate/atropine (Lomotil) and difenoxin/atropine (Motofen).

Dosing

Loperamide is commonly used to treat diarrhea and acute gastroenteritis in adults. It’s crucial to consult with your healthcare provider before adjusting your medication dosage.

Diarrhea

The standard initial dose for adults suffering from diarrhea is 4 mg, followed by 2 mg after each loose stool. The daily dose should not exceed 16 mg.

Acute Gastroenteritis

For acute gastroenteritis, the dosing is similar to that of diarrhea, starting with 4 mg, then 2 mg after each loose stool, not exceeding 16 mg per day.

Dosage Forms and Strengths

Loperamide is available in two forms: tablet and liquid. The tablets are available in a 2 mg strength, and the liquid form is available in a 1 mg/7.5 ml concentration.

Administration Instructions

Loperamide tablets should be taken with liquid, and the liquid form should be measured using the provided cup. It can be taken with or without food.

Adverse Reactions and Side Effects

Although loperamide is generally well tolerated, like all medications, it can cause side effects.

Constipation (Common)

Loperamide works by slowing down the movement of the gut, which can sometimes lead to constipation.

Dizziness (Less Common)

Dizziness is a less common side effect of loperamide. This occurs because the medication can affect the nervous system.

Contraindications to Taking Loperamide

Contraindications refer to situations where a drug should not be used because it may be harmful to the patient.

Abdominal Pain without Diarrhea

Loperamide should not be used if you have abdominal pain without the presence of diarrhea, as it could exacerbate the underlying condition causing the pain.

Allergic Reaction to Loperamide

If you have ever had an allergic reaction to loperamide, you should avoid this medication.

Drug to Drug Interactions

Loperamide can interact with several other medications, including:

Quinidine (Quinidex)

Quinidine can increase the concentration of loperamide in the body, potentially leading to more side effects.

Ritonavir (Norvir)

Ritonavir can also increase loperamide concentrations, leading to increased risk of side effects.

Loperamide in Pregnancy

Loperamide should only be used in pregnancy if clearly needed and after consultation with your healthcare provider.

Loperamide while Breastfeeding

Loperamide is considered safe to use during breastfeeding in normal doses, but it’s always best to consult your healthcare provider.

The estimated cost of a 30-day supply of Loperamide (2 mg, two tablets after the first loose stool, followed by one tablet after subsequent loose stools, not to exceed 8 tablets per day) without insurance, using a GoodRx coupon, is approximately $10. Please note, these costs are estimated and may vary based on location, pharmacy, and changes in pharmaceutical agreements.
