What is naltrexone 50 mg used for?
Naltrexone is prescribed in tablets, commonly at 50 mg, to treat alcohol use disorder and opioid use disorder. It works by blocking opioid receptors, which can reduce the rewarding effects of opioids and alcohol-related behaviors for some people.
How does naltrexone 50 mg work?
Naltrexone blocks the brain’s opioid receptors. That means if someone uses opioids after taking naltrexone, the drugs’ effects are diminished. In alcohol use disorder, naltrexone can reduce cravings and the rewarding effects some people experience with alcohol.
How is naltrexone 50 mg taken?
The specific dosing schedule depends on the condition being treated and the prescribing clinician’s instructions. For alcohol use disorder, clinicians often use a daily regimen of 50 mg. For opioid use disorder, patients typically must be opioid-free before starting to avoid precipitated withdrawal.
What side effects do people ask about with naltrexone 50 mg?
Commonly reported side effects can include nausea, headache, dizziness, fatigue, and insomnia. Because naltrexone can affect the liver, healthcare providers often evaluate liver function before and during treatment, especially if there are other liver risk factors.
What happens if you take opioids while on naltrexone?
Opioids may work less or not at all while naltrexone is active. Taking opioids despite being on naltrexone can still be risky and should be discussed with a clinician—especially if pain control is needed. If someone needs emergency pain treatment, they should tell medical staff they take naltrexone.
Can you drink alcohol while taking naltrexone 50 mg?
Naltrexone can reduce alcohol’s rewarding effects, but it does not make drinking safe. Patients are typically advised to follow their treatment plan for alcohol use disorder, which often includes limiting or avoiding alcohol while on therapy.

What questions should you ask your prescriber before starting or continuing?
Common practical questions include:
- Whether you’ve been opioid-free long enough (if treating opioid use disorder).
- Your liver history and whether you need blood tests (liver enzymes).
- What to do if you need surgery or pain medication.
- How long you should stay on treatment and how progress will be measured.
