Naltrexone is a medication used to treat alcohol and opioid dependence. While it is generally safe when used as prescribed, it is still possible to overdose on naltrexone if it is taken in excessive amounts.

Symptoms of a naltrexone overdose can include nausea, vomiting, stomach pain, dizziness, seizures, hallucinations, and difficulty breathing. If you suspect that you or someone else has taken too much naltrexone, seek medical attention immediately.
