Quitting drinking: What are the differences between Vivitrol and Naltrexone pills?
posted by anonymous to Home & Garden (2 answers total)
I want to know if there are differences between the ways Vivitrol and Naltrexone pills work.
I know Vivitrol is a time-released medication. It's typically injected once a month in a 380 mg dose. Naltrexone pills, on the other hand, are prescribed at 50 mg/day. I don't understand how approximately 1500 mg/month (via pills) can be comparable to 380 mg (Vivitrol injection). What are the differences between these methods of administering the medication? Is one better than the other?
I know you are not my doctor. But my doctor--actually three doctors--have not been able to explain this to me. I think the confusion might be related in part to the differing opinions about how Naltrexone should be used (i.e.., abstinence vs drinking while on the drug).
I'm particularly interested in knowing if Vivitrol will work for a person trying the Sinclair Method to quit drinking. I understand that in later months/years of the Sinclair method, a person takes a Naltrexone pill before drinking (so injections at that point would be unnecessary). But in the early stages of quitting, does Vivitrol work in the same way as the daily pills?
