General Information On Revia
Revia (Naltrexone) helps in blocking the effects of narcotic and alcoholic substances. This is the reason why this oral drug is used to treat narcotic substance addiction or alcohol addiction. The chief reason for this drug’s success in treating narcotic or alcohol addiction is because it is an opioid antagonist, which means it completely blocks and reverses the effect caused by any narcotic substance in the body. In certain cases, the use of this drug precipitates withdrawal symptoms.
Side Effects for Revia
The common side effects of Revia include mild withdrawal symptoms like nausea, stomach cramps, bone or joint pain, blurred vision, hallucinations, confusion, mood changes and breathing difficulty. Other side effects include restlessness, anxiety, depression, irritability, lightheadedness, fainting, excessive thirst, weakness, insomnia, decreased libido, inability to have an orgasm, and impotence. In some cases, the patients also exhibit a tendency towards suicidal thoughts and attempts.
A change in the color of stools and urine is another common side effect of using Revia. Moreover, in some cases, patients exhibit jaundice like symptoms where the skin and eyes are yellow in color.
It is important to get immediate medical help if you exhibit any of the above symptoms.
Always ensure that you do not consume Revia in a higher dosage than prescribed by your doctor, as an overdose is known to cause hepatocellular injury. This drug can turn into a hepatotoxin if consumed excessively, which means it can have adverse results in patients suffering from acute hepatitis or liver failure. Always inform your doctor about any kidney disease, liver disease, occurrence of hemophilia or other bleeding disorders before you buy Revia.
It is important to avoid this drug if you are allergic to Naltrexone or are experiencing acute drug or alcohol withdrawal symptoms. It is also important to discontinue the use of any drug or alcohol when you are being treated with Revia. Do not use this drug if you have consumed alcohol or drugs in the previous seven to ten days.
Carry some form of identification that indicates that you are consuming this drug at all times, so that this is considered if you need to be treated for any emergency.
Although there is no known adverse effect caused by this drug during pregnancy, it is important to inform your doctor if you are pregnant and discuss the pros and cons of its usage before you actually start using the drug.
Revia 50mg is the recommended dosage for most patients. The usual regimen for this drug entails that you consume the drug daily for at least 12 weeks. However, it is important that the patient does not consume any alcohol or narcotic substance when consuming the daily dose of Revia 50mg. As mentioned earlier, it is important to carry any form of paper or tag on your body to show that you are consuming this medication. For effective treatment, it is important that you consume this medication orally.
It is important to note that Revia interferes and blocks the mechanisms of any pain relieving narcotics, which would automatically mean that you will actually experience the pain. Additionally, the drug also interacts adversely with other drugs like Buprenorphine, Butorphanol, Dezocine, Methadone, Naloxone, Oxycodone, and many more. It is important to inform your doctor about any such drug or medication usage before you start using Revia.

What is a "Generic" medication/drug?
Generic drugs are medications that have comparable medicinal ingredients as the original brand name drug, but which are generally cheaper in price. Nearly 1 in 3 drugs dispensed are "generic". They undergo testing to ensure that they are similar to their "brand" counterparts in:
- Active Ingredient (e.g. "Pravastatin" is the active ingredient in brand name Pravachol)
- Dosage (e.g. 10 mg of the active ingredient)
- Safety (e.g. same or similar side effects, drug interactions)
- Performance (e.g. 10 mg of a "generic" can be substituted for 10 mg of the "brand" and have the same therapeutic result)
- Intended use (e.g. both "generic" and "brand" would be prescribed for the same conditions)
What this means is that "generic" medications can be used as a substitute of their brand equivalents with the comparable therapeutic results. There are a few exceptions (examples are outlined at the end of this page) and as always you should consult your physician before switching from a brand name medications to a generic or vice versa.
What differences are there between generic and brand?
While generics and brand equivalent drugs contain the same active ingredients, they may be different in the following ways:
- Appearance (e.g. the scoring or markings)
The color, shape and size of the medication come from the fillers that are added to the active ingredients to make the drug. These fillers that are added to the drug have no medical use and do not to change the effectiveness of the final product. A generic drug must contain comparable active ingredients and must have a comparable strength and dosage as the original brand name equivalent. Generic drugs can be more cost effective than purchasing the brand name.
Why do generics cost less than the brand name equivalents?
When a new drug is "invented", the company that discovered it has a patent on it that gives them the exclusive production rights for this medication. Once the patent expires in a country, other companies can bring the product to market under their own name. This patent prevents other companies from copying the drug during that time so they can earn back their Research and Development costs through being the exclusive supplier of the product. After the patent expires however, other companies can develop a "generic" version of the product. These versions generally are offered at much lower prices because the companies do not have the same development costs as the original company who developed the medication.
The main thing to realize here though is that the two products are therapeutically equivalent. They may look different, and be called something different.
How are Generic drugs tested to ensure quality and efficacy?
Generally speaking, the two most generally accepted methods to prove the safety of a generic version of a drug are to either repeat most of the chemistry, animal and human studies originally done, or to show that the drug performs comparably with the original brand name drug. This second option is called a "comparative bioavailability" study. During this type of study, volunteers are given the original drug, and then separately later the generic drug. The rates at which the drug is delivered to the patient (into their blood stream or otherwise absorbed) are measured to ensure they are the same. Because the same active ingredient is used the major concern is just that it delivers the common chemical(s) at the same rate so that they have the same effect. Please note that the methods that the manufacturers use may vary from country to country.
