Revia (naltrexone) is a common drug used to help people stop drinking or prevent opioid relapse. It can work well, but it also has side effects that vary from mild to serious. This page tells you the usual problems people report, the big risks to watch for, and practical tips to manage side effects so you can make safer choices with your doctor.
Most people who take Revia notice only a few mild effects. Expect things like nausea, headache, tiredness, dizziness, or trouble sleeping. Some report anxiety, muscle or joint aches, and reduced appetite. These often start in the first few days and ease as your body adjusts.
If you or a friend is trying low‑dose naltrexone (LDN) for off‑label uses, side effects are usually milder—sometimes just vivid dreams or brief sleep trouble. Still, everyone reacts differently, so keep an eye on new symptoms and mention them to your prescriber.
Revia can affect the liver. Your doctor will often check liver tests before and during treatment. Watch for dark urine, yellowing of skin or eyes, severe stomach pain, or unexplained tiredness—these can signal liver trouble and need urgent medical care.
Never use Revia with opioid drugs. It blocks opioid effects and can trigger sudden, severe withdrawal if you still have opioids in your system. Tell every health provider that you’re on naltrexone—this matters for pain control, surgery, or emergency care. For planned surgery, clinicians usually recommend stopping oral naltrexone at least 72 hours before expected opioid use; injectable forms need much longer.
Other serious issues include severe allergic reactions and new or worsening depression or suicidal thoughts. If mood changes or severe shortness of breath, swelling, or rash appear, get help right away.
Simple steps to reduce problems: start with the dose your doctor prescribes, drink plenty of water, avoid heavy alcohol while your liver is being checked, and report any new pain or mood changes. If nausea is bad, taking the pill with food can help. Some people shift timing (morning vs. bedtime) to reduce sleep issues—ask your prescriber first.
Finally, be honest about current medications and recent opioid use before starting Revia. That short conversation prevents most serious risks. If you’re unsure whether a symptom is serious, call your doctor or local health services—better safe than sorry.
