This is a case report of a patient with sleepwalking likely caused by tapentadol ER secondary to higher than the recommended dose for the treatment of pain. This report presents the relevant patient history, laboratory data and literature review on possible causes of this patient's sleepwalking. A 39-year-old female reported sleepwalking as the dose of tapentadol increased above the recommended maximum provided in the package insert. The mechanism of action of tapentadol involving norepinephrine reuptake inhibition affecting the central nervous system, higher dosage and drug interactions with other home medications likely contributed to her sleepwalking. This case highlights the importance of adhering to the recommended dosage of a medication and if it is clinically warranted to exceed the maximum recommended dose, the importance of diligent monitoring for any adverse effects.
