  • Reduced awareness or responsiveness
  • Confusion
  • Abnormal heart beat (Arrhythmia)

Adverse reactions indicating overdosage must be attended to by qualified medical personnel in a clinical environment immediately. There is no available antidote specific to Contrave overdose, however medical personnel will administer appropriate supportive care and close monitoring and supervision of all vital signs in particular.
