Low-dose buprenorphine initiation, sometimes called microinduction, is a strategy that starts buprenorphine in very small amounts and increases it gradually while a full opioid agonist may still be present. Unlike standard induction, the person does not necessarily need to wait for moderate withdrawal before the first very small dose.
Why is low-dose initiation used?
The approach may be considered when standard induction is difficult or when clinicians want to reduce the risk of precipitated withdrawal. It has received particular attention in the fentanyl era because repeated fentanyl exposure can make the timing of standard buprenorphine initiation less predictable.
How does microinduction work?
The basic concept is gradual receptor transition. Very small buprenorphine doses are introduced and increased over time while the full opioid agonist is reduced or stopped according to the clinical plan. Buprenorphine gradually occupies more opioid receptors rather than displacing the other opioid all at once.
Is microinduction an official FDA-approved dosing protocol?
No single “microinduction” schedule is FDA-approved as a standard protocol. The strategy is an evolving clinical practice supported by growing evidence and professional guidance. Specific dosing schedules vary and should be managed by qualified clinicians.
How is low-dose initiation different from standard induction?
With standard buprenorphine induction, clinicians generally wait until sufficient opioid withdrawal is present before giving the first dose. Low-dose initiation starts with much smaller doses before that point and overlaps with ongoing opioid exposure for a period.
Who might be considered for low-dose initiation?
Clinicians may consider it for people with heavy fentanyl exposure, people transitioning from methadone or prescribed opioids, people with a history of precipitated withdrawal, or people who cannot tolerate a period of untreated withdrawal. It is not automatically the best strategy for everyone.
Can microinduction be done without medical supervision?
It should not be improvised from general internet instructions. The medication plan depends on the opioid involved, current dose or exposure, medical conditions, other medications, and the treatment setting.
What happens after low-dose initiation?
Once buprenorphine has been increased to a therapeutic level and the full agonist is stopped, the patient continues maintenance treatment as clinically appropriate. The ongoing dose is adjusted based on cravings, withdrawal symptoms, side effects, and treatment goals.
Does microinduction eliminate all risk of precipitated withdrawal?
No. It may reduce risk in selected situations, but precipitated withdrawal can still occur. Close monitoring and a clear clinical plan remain important.

Frequently asked questions
Is microinduction the same as the Bernese method?
The terms are often used interchangeably, although low-dose initiation is a broader category and specific protocols vary.
Can low-dose initiation be used with fentanyl?
Yes, clinicians may consider it for people using fentanyl when standard induction presents challenges.
Can someone stay on methadone during low-dose buprenorphine initiation?
Some protocols overlap methadone and very small buprenorphine doses during a supervised transition, but the plan must be individualized.
Is microinduction faster than standard induction?
Not necessarily. It can take several days or longer depending on the protocol and clinical situation.
