Dosage Guidelines & Tips
How to take Revia (Oral)?
Use Revia (Oral) exactly as directed on the label, or as prescribed by your doctor. Do not use in larger or smaller amounts or for longer than recommended.
Follow all directions on your prescription label and read all medication guides or instruction sheets. Use the medicine exactly as directed.
Your doctor may recommend you have a family member or other caregiver make sure you take naltrexone on schedule, to make sure you are using the medicine correctly as part of your treatment.
Wear a medical alert tag or carry an ID card to let others know you use naltrexone.
Naltrexone is only part of a complete treatment program that may also include additional forms of counseling and/or monitoring. Follow your doctor's instructions very carefully.
Store tightly closed at room temperature, away from moisture and heat. Protect from light.
After taking naltrexone, your body will be more sensitive to opioids. If you use an opioid medicine in the future, you will need to use less than before the naltrexone treatment. Using the same amount you used before could lead to overdose or death.
Take the medicine as soon as you can, but skip the missed dose if it is almost time for your next dose. Do not take two doses at one time.
