Drug Description


Lactaid Fast Act Chewables are used to manage lactose intolerance, a condition where the body lacks the necessary enzyme (lactase) to break down lactose, a sugar predominantly present in milk and dairy products. 

Lactaid Fast Act Chewables are lactase enzyme supplements that aid those with lactose intolerance in consuming dairy without discomfort. It works like the body’s naturally produced enzyme (lactase) to break down lactose into glucose and galactose, effectively alleviating symptoms like diarrhea, bloating, cramps, and gas. 

Uses and Dosage
