Revia (Naltrexone)

Revia is used for treating alcoholism and narcotic (opioid) addiction in adults, as part of a complete treatment program. It may also be used to treat other conditions as determined by your doctor.

Use Revia as directed by your doctor. Check the label on the medicine for exact dosing instructions.

• Take Revia by mouth with or without food.
• Revia should not be taken until the naltrexone challenge test is negative.
• Before taking Revia , you must be willing to take Revia to help with alcohol dependence, you must be free of substance abuse for 7 to 10 days, you must not have any severe or active liver or kidney problems, and you must not have any other medical problems or conditions that make taking Revia inadvisable.

Revia is a narcotic antagonist. It is thought to work by blocking the effects of injectable opioids (e.g., heroin, narcotic pain relievers). It has also been shown to decrease alcohol consumption.

If you miss a dose of Revia, skip the missed dose. Go back to your regular dosing schedule. Do not take 2 doses at once.

Store Revia at 77 degrees F (25 degrees C). Brief storage between 59 and 86 degrees F (15 and 30 degrees C) is permitted. Store away from heat, moisture, and light. Do not store in the bathroom. Keep Revia out of the reach of children and away from pets.

Do not use Revia if:

• you are allergic to any ingredient in Revia;
• you are taking narcotic medications for pain, are dependent on narcotics, are experiencing withdrawal symptoms from narcotics, have failed the challenge test with Revia , or have tested positive for narcotics;
• you have hepatitis, liver failure, or liver disease.

• Do not drive or perform other possibly unsafe tasks until you know how you react to it.
• Carry identification to alert health care providers that you are taking Revia . You can get a medication card from your doctor to use for this purpose.
• Before you have any medical or dental treatments, emergency care, or surgery, tell the doctor or dentist that you are using Revia.
• Contact your health care provider at once if any of the following signs or symptoms of hepatitis occur while taking Revia : stomach pain lasting more than a few days; white bowel movements; dark urine; yellowing of the skin or eyes.
• Do not use narcotics while taking Revia , including opioid-containing medicines (e.g., cough and cold products, pain relievers, heroin). Revia may increase your sensitivity to narcotics. Therefore, even very low doses may cause coma or be life-threatening.
• Before you have any medical or dental surgery or emergency treatments, tell the doctor or dentist that you are taking Revia.
• Lab tests, including liver function, may be performed to monitor your progress or to check for side effects. Be sure to keep all doctor and lab appointments.
• Use Revia with extreme caution in children younger than 18 years of age. Safety and effectiveness in this age group have not been confirmed.
• Pregnancy and breast-feeding: If you become pregnant, discuss with your doctor the benefits and risks of using Revia during pregnancy. It is unknown if Revia is excreted in breast milk. If you are or will be breast-feeding while you are using Revia , check with your doctor or pharmacist to discuss the risks to your baby.

• anxiety; appetite loss; chills; constipation; delayed ejaculation; diarrhea; dizziness; drowsiness; feeling down; headache; increased energy; increased thirst; irritability; joint and muscle pain; low energy; nausea; nervousness; sleeplessness; stomach pain/cramps; vomiting.
