In clinical trials, DAYVIGO did not lead to signs or symptoms of withdrawal after discontinuation, suggesting that it does not produce physicaldependence in those taking it. DAYVIGO is a federally controlled substance because it can be abused or cause dependence. If you have a history of abuse or addiction to alcohol or other drugs, you may have an increased risk and should talk to your healthcare provider before taking DAYVIGO. Keep DAYVIGO in a safe place to prevent misuse and abuse. Selling or giving away DAYVIGO may harm others and is against the law. Tell your doctor if you have ever abused or have been dependent on alcohol, prescription medicines or street drugs.
