Donnatal, a combination of phenobarbital, hyoscyamine, atropine, and scopolamine, has a variable duration in the body depending on individual factors like metabolism and dosage. The half-life of phenobarbital, one of its active components, is approximately 80 to 120 hours, meaning it can take several days to be eliminated from the system. The other ingredients may have shorter half-lives, but the effects of Donnatal can last several hours. Always consult a healthcare professional for personalized information regarding medication effects and duration.
