What is a Generic Drug?

A generic drug is a copy of the brand-name drug with the same dosage, safety, strength, quality, consumption method, performance, and intended use. Before generics become available on the market, the generic company must prove it has the same active ingredients as the brand-name drug and works in the same way and in the same amount of time in the body.

The only differences between generics and their brand-name counterparts is that generics are less expensive and may look slightly different (eg. different shape or color), as trademarks laws prevent a generic from looking exactly like the brand-name drug.

Generics are less expensive because generic manufacturers don't have to invest large sums of money to develop a drug. When the brand-name patent expires, generic companies can manufacture a copy of the brand-name and sell it at a substantial discount.


Revia is a prescription addiction treatment medication used for treating alcohol or opioid dependency. It is part of the opiate antagonist class of drugs used as part of an addict recovery program to reduce physiological cravings or withdrawal symptoms when attempting to overcome addiction. It is most used as part of a larger addiction treatment regimen that will likely include counselling, lifestyle changes, and compliance monitoring but for many people Revia is effective for curbing the desire to use substances.

You can order Revia with a prescription, and your best price on it will be when you order medication online from Canada Drugs Direct.


Revia 50mg is typically taken one time a day and with or without food, but dosage may vary, and you should always take medication exactly as indicated in your prescription. Your doctor may prescribe a higher dose of 100 - 150 mg to be taken every 2 -3 days based on your needs / response and this administration may have to be supervised.

A urine test may be required to check for recent substance use as Revia cannot be used while the patient is using opiates. Do not use any opiates for at least 7 days before starting on Naltrexone if the medication is being used to treat opioid addiction.

It is best to take this medication at the same time each day.


The active ingredient in Revia is Naltrexone.


Tell your doctor if you have any history of kidney or liver disease before starting on Revia.

It is best to carry or wear medical identification stating you are using the addiction recovery medication so that you can receive appropriate treatment in the event of an emergency.

Once you are prescribed and buy Revia, then keep medication in a secure place and out of the reach of others.

It is important that you do not stop taking this medication and complete your course of treatment exactly as it has been laid out by your doctor.


There is the possibility of negative drug interactions between Revia and other Rx medications, including dextromethorphan / diphenoxylate / disulfiram / opioid pain or cough relievers like codeine and hydrocodone / thioridazine. Tell your doctor of all medications you are currently taking before getting a prescription and proceeding to buy Revia.

Side Effects

Revia side effects are uncommon, but some users may experience nausea, headache, dizziness, tiredness, or sleeping difficulties. Opiate withdrawal symptoms are possible too and may come with abdominal cramps, restlessness, bone or joint pain, muscle aches, or a runny nose. If Revia side effects worsen or become intolerable you may want to discontinue use and speak to your doctor again about substance abuse treatment medication alternatives.
