Naltrexone is an opioid receptor antagonist used for the treatment of opioid and alcohol dependence. It works by blocking the effects of opioids and reducing cravings, helping patients maintain abstinence.
The medication is taken orally, usually once daily, with the dose adjusted based on the patient's needs. Common side effects include nausea, headaches, insomnia, and irritability.
Naltrexone is contraindicated in patients actively using opioids or with severe hepatic impairment. Its use also requires careful monitoring to prevent severe adverse reactions.
This medication is an important option for patients seeking to quit opioids or alcohol, helping to reduce relapses and improve quality of life.
