Revia How to Take

Revia (Naltrexone) belongs to a group of medications known as pure opioid antagonists. It is used to help individuals who were previously dependent on drugs of addiction (such as alcohol, or opiate drugs such as Methadone and heroin) to remain free from their dependence.

Opiate drugs (also known as opioid drugs) and opioids that are naturally part of the body affect certain parts of the brain called opiate receptors. Revia (Naltrexone) works by binding to these opiate receptors to block the effects of opiates drugs and the body's own opiates. It is believed that this helps prevent a person from returning to using these substances.

Revia (Naltrexone) is used together with other forms of treatment such as psychological counselling and social support.

Your doctor may have suggested Revia (Naltrexone) for conditions other than those listed in these drug information articles. As well, some forms of Revia (Naltrexone) may not be used for all of the conditions discussed here. If you have not discussed this with your doctor or are not sure why you are taking Revia (Naltrexone), speak to your doctor. Do not stop taking Revia (Naltrexone) without consulting your doctor.

Do not give Revia (Naltrexone) to anyone else, even if they have the same symptoms as you do. It can be harmful for people to take Revia (Naltrexone) if their doctor has not prescribed it.

Revia Dosage

The dose of Revia (Naltrexone) depends on the type of dependence it is being used to treat, and whether administration of the medication will be supervised.

To treat Alcoholism, the usual recommended dose is 50 mg once daily.

To treat opioid dependence (e.g., addiction to methadone or heroin), the dose will vary but the usual starting dose is 25 mg once daily, to be slowly increased to the most appropriate dose.

Your doctor will determine a dose and dosing schedule for your individual situation. It is important that you take Revia (Naltrexone) exactly as prescribed by your doctor.

Your doctor may request a urine sample before initiating treatment with Revia (Naltrexone) in order to make sure that you have not used any narcotics (opioid drugs) within the previous 7 to 10 days. You should not take Revia (Naltrexone) if there is any possibility that you have used an opiate within the previous 7 to 10 days. If there is any question about your opiate use, your doctor may request that you take a NARCAN challenge test in order to confirm that your body is opiate-free before you take Revia (Naltrexone).

If you miss a dose, take it as soon as possible and continue with your regular schedule. If it is almost time for your next dose, skip the missed dose and continue with your regular dosing schedule. Do not take a double dose to make up for a missed one. If you are not sure what to do after missing a dose, contact your doctor or pharmacist for advice.

Store Revia (Naltrexone) at room temperature, protect it from light and moisture, and keep it out of the reach of children.

Do not dispose of medications in wastewater (e.g. down the sink or in the toilet) or in household garbage. Ask your pharmacist how to dispose of medications that are no longer needed or have expired.

Alcohol: You should not drink alcohol while taking Revia (Naltrexone) as this could damage your liver.

Interference with opiate-containing mediations: Because Revia (Naltrexone) works by blocking the effects of opiates, it may interfere with other medications that contain opiates such as certain cough and cold medications, antidiarrheal medications, and some analgesics (pain medications).

Suicide: People with substance abuse problems are at a higher risk of suicide. The use of Revia (Naltrexone) does not lower this risk.
