Side effects. The most common side effects reported with naltrexone are gastrointestinal complaints such as diarrhea and abdominal cramping. These adverse effects are analogous to the symptoms of opioid withdrawal, as the mu receptor blockade will increase GI motility. Naltrexone has been reported to cause liver damage (when given at doses higher than recommended).
1 Your doctor will tell you not to take naltrexone if you have taken or used opioids in the past 7 to 10 days.  do not take any opioid medications or use opioid street drugs during your treatment with naltrexone.

If you take or use higher doses of opioid medications or drugs during your treatment with naltrexone, it may cause serious injury, coma (long-lasting unconscious state), or death.
