Each opiate has its own brand of withdrawal symptoms. ...but much of each one depends on time factors as well as mental and physical factors.
1. How long one has been on the drug.
2. How old the person is.
3. How much has been taken.
4. Emotional stability
5. Physical condition
6. Education and support during usage and detox.
Buprenorphine, if prescribed at doses under 2mgs for less than a year, can be easily gotten off of. However, risk of worse wd symptoms happens when higher doses are taken. Each individual Is different, younger people tend to fare better, also those in very good physical condition that work out with some regularity produce their own endorphins faster...that is a big step towards brain healing.
Your brain does not begin to heal from opiates until they are no longer present in your system., however mental clarity gets better the closer one gets to abstinence.
Bupe can be very hard to detox in a medical setting because the orIginal manufacturer intended it to be used for short detox off Short acting opiates, SAOs. Bupe, like Methadone, is a long acting opiate LAO. This means the half life is longer so it covers a longer period of time before wds start. SAO detox symptoms start 8-12 hours after last dose. LAO detox symptoms start 36-72 hours after last dose depending on the amount of "stack" one has in their body.
Detoxers report that bupe has more mental issue than physical and that it drags out longer. Many report serious depression worse than what they had experienced with heroin or methadone.
So...it does depend on quite a few factors....bupe needs to be tapered down to LESS than one quarter of a milligram, .25 or less...over a period of 3-8 months depending on starting dose. It is not something that takes less than 3 months. Many sub Drs have no clue how long or how low a client should take or be before they stop. That was not a part of the 8 hour training. Many think a taper of a few weeks to 2mgs is all a person needs. That is so far from the truth but once again, the original manufacturer did not teach Drs how to get people off a drug that is now being marketed for maintenance .
