How long does Imodium work? Won't diarrhea come back?

After taking Imodium, it begins to work after about 1 hour. The strongest effect of the drug is observed after about 5 hours. The half-life of the drug is about 11 hours, so after about 55 hours (5 half-lives), the drug will not be in the body. Diarrhea is usually self-limiting and properly treated symptomatically, usually does not give dangerous or permanent consequences.
