Your healthcare provider will determine an appropriate dosage of Revia based on the reason you are taking this medication, how you respond to it, and various other factors. The initial amount will usually vary between 25 mg and 50 mg each day. However, if you need supervision to ensure you are taking this drug, you may receive higher amounts.
The dose of Revia® (naltrexone) your healthcare provider recommends will vary, depending on a few factors, including:
- Why you are taking Revia
- How you respond to it
- Whether you will be taking the medication on your own or if someone else will be giving it to you.
As is always the case, do not adjust your dosage unless your healthcare provider specifically tells you to do so.
The recommended dosage for treating alcohol dependence is usually 50 mg once a day. If you experience side effects, such as significant nausea, your healthcare provider may recommend you take Revia 25 mg a day until your symptoms subside and then increase your dose to 50 mg a day. Alternatively, some healthcare providers may recommend 25 mg twice a day to help limit side effects.
The recommended initial Revia dosage for the treatment of opioid dependence is usually 25 mg once a day. Unless symptoms of opioid withdrawal occur, this amount is usually increased to 50 mg a day.
You should not take Revia if you have taken an opioid in the past 7 to 10 days (for most opioids) or in the past two weeks for medications containing buprenorphine or methadone, since those opioids are long acting. Your healthcare provider may check for the presence of opioids in your system by testing your urine, or by giving you a medication called naloxone (Narcan®). People who have recently taken opioids will develop opioid withdrawal symptoms when given naloxone.
A healthcare provider may sometimes recommend supervised administration of Revia, which means someone will give you the medication to ensure you are taking it. In such cases, alternative dosing strategies may be needed, such as taking Revia 100 mg every other day or 150 mg every three days. Your healthcare provider will recommend the best dose for your particular situation.
