Compare Imodium (multi symptom) vs. Prevalite

Loperamide (Imodium A-D) and cholestyramine (Prevalite) are both oral medications but serve different purposes. Loperamide is an antidiarrheal available over-the-counter and by prescription, used to control symptoms of diarrhea and manage chronic gut-related conditions. It works by slowing down bowel movements and reducing fluid in the intestines. Cholestyramine, on the other hand, is a prescription-only bile acid sequestrant used to lower cholesterol and treat itching caused by bile duct blockage. It binds to bile acids in the intestines, which helps lower cholesterol levels. While loperamide can cause dizziness, drowsiness, and constipation, cholestyramine may lead to constipation, stomach discomfort, and potential vitamin deficiencies. Additionally, cholestyramine requires careful timing with other medications to avoid absorption issues, whereas loperamide has specific dosing limits to prevent serious heart rhythm problems.
