Revia is a drug used on people dependent on narcotics who have chosen to stop to stay drug-free. Apart from that, it also helps alcoholics stay away from alcohol.
Revia use is a part of an overall program, which may also include attending support group meetings, counseling, and any other treatments that your doctor may recommend. This drug is not a narcotic; it only works by blocking its effects, particularly the “high” feeling, which makes you want to use more of it.
Revia does not produce the effects that usually cause physical and mental dependence. Using this drug may cause withdrawal symptoms in people who are dependent on narcotics physically; hence, the treatment will start when you are no longer dependent on it. The span of treatment generally depends on the kind of narcotic you are dependent on, the amount you took, and how long you used it.
Inform your doctor if you are still having withdrawal symptoms prior to using this medicine. The medicine is available only with the prescription of your doctor.

4 Precautions to Take

Using this drug may cause serious liver problems. If you notice having dark urine, upper stomach pain, or yellowing of the eyes or skin, inform your doctor right away. Using this drug may also increase your risk for eosinophilic pneumonia, a type of lung disease.
It may also cause anaphylaxis, a life-threatening allergic reaction characterized by itching, rash, hoarseness, swallowing and breathing difficulties, or swelling of the face, mouth, or hands.
Before starting to use naltrexone, you need to stop narcotics use for at least 7 days. Your doctor may require you to undergo several tests, such as a urine test or naloxone challenge test to make sure you are opioid-free. Do not use any other narcotic drugs, including heroin, during treatment.
Naltrexone makes you more sensitive to opioids, even at lower doses and taking narcotics only ups your risk for an overdose or in developing serious problems. Using this drug may also bring in suicidal thoughts. Inform your doctor right away if you feel more depressed or are having suicidal thoughts during the course of treatment.
