I’ve been on Suboxone for 15 years. I just got a little bit of fentanyl. How long do I have to wait before I can take it?

Honestly to get the best out of it I recommend 4-5 days since bup has a much higher affinity for opiate receptors. What I did was switch to poppy seed tea for those four days then did my Fent as Fent has a higher binding affinity than morphine and the bup has alenough time to be cleared out of you’re system. You gotta wait a few days because buprenorphine has such a long half life.and then switch back to the tea for a 3-4 days because if you take bup right after it can send you into withdrawal with its higher binding affinity and only a partial opiate agonist

You can go straight on you may know. But the effects will be diminished…I believe the rule of thumb is when you begin to go in to paws. As stated go cautiously from opioid back to Bup. If naloxone is in the mix…definitely abstain.

I went from 80mg methodone to Bup 2-3 days can’t remember exactly… I had Dxm on board as well. Until recently I was on Bup 24mg for about 4yrs.
