Can you overdose and die on paroxetine?

Yes bit unlikely. An overdose with antidepressants like paroxetine alone is usually not fatal. However, mixed with alcohol or other sedating drugs things can get bad in a hurry and you can die. Also if it is a child or an elderly person or someone who is medically ill and you take a large amount of paroxetine then death is a possible outcome. Keep all meds in a safe place & take only as directed by your dr.
