Tapering off Phenibut
Also sold as phenibut, Noofen, Anvifen, beta-phenyl-GABA.
Coming off Phenibut is far gentler when the dose comes down gradually, in steps that shrink as you approach zero. This is what a hyperbolic taper looks like for Phenibut, why it helps, and how to build one to review with your prescriber.
Why Phenibut needs a gradual taper
Phenibut produces real physical dependence with regular use, so coming off it goes far more smoothly as a gradual taper than as a sudden stop.
Phenibut has an intermediate half-life (~5 h), long enough for reasonably steady levels through the day while still needing gradual, well-spaced reductions.
Please read this one carefully, because phenibut is different from the others here. It is a GABA-B agonist, so its dependence and withdrawal are benzodiazepine-like, not opioid-like. Stopping abruptly after regular high-dose use can be genuinely dangerous (severe anxiety, insomnia, tremor, and in serious cases hallucinations or seizures), so this is one to taper slowly and ideally with medical supervision, especially at higher daily doses. The good news: it is very taperable. Clinicians often use a slow reduction or a cross-taper to a longer-acting agent like baclofen, and people recover. Avoid combining with alcohol, benzodiazepines, or other sedatives.
Abruptly discontinuing Phenibut after regular high-dose use can be dangerous, including the risk of seizures. Every reduction should be gradual and guided by a prescriber. If you have a seizure, severe confusion, or thoughts of self-harm, seek urgent care. In crisis, call or text 988 (US) or see the safety page.

The real engine runs right here. Enter your daily dose to watch a hyperbolic schedule take shape, no signup.
Slow is the point: gradual tapers are why ~70% succeed where cold turkey fails. Your full plan adds safety screening, exact dose recipes, and adapts to your check-ins.
Educational preview, not medical advice. Taper with a prescriber, never stop abruptly.
What your Phenibut plan includes
Before any schedule, a short intake flags the situations where you should slow down or check with a clinician, so the plan starts from your actual picture.
A hyperbolic schedule sized to Phenibut: the milligram cuts shrink as the dose falls, so the steps get gentler exactly where they need to.
The small end-of-taper doses made reachable. Below the smallest tablet, Subside spells out the practical options (careful splitting of the scored tablet or a compounding pharmacy) instead of leaving you to guess.
Your check-ins feed back into the plan: rough stretches trigger a hold or a gentler pace, and reinstatement (stepping back up to stabilize) is a first-class option, never a failure.
When symptoms show up, the plan reads them against the timing of your last reduction, so you can tell an expected wave from something that needs a different response.
Common questions about coming off Phenibut
How long does a Phenibut taper take?+
It varies widely with your dose and how long you have taken Phenibut, so quoting a single number would be misleading. Subside computes the length from your exact dose and adjusts as you go, larger steps at the top and smaller ones through the sensitive low-dose tail, with holding longer always allowed.
Can I stop Phenibut cold turkey?+
No. Phenibut acts on the brain's GABA system, so stopping abruptly after regular high-dose use can be dangerous, including severe anxiety, insomnia, tremor, and in serious cases seizures. Reduce it slowly and, especially at higher daily doses, with medical supervision.
What are common Phenibut withdrawal symptoms?+
Because these products act on opioid or GABA systems, withdrawal tends to follow that pattern (see the specific cautions above). It eases considerably with a gradual, steady reduction.
Do I need a doctor to taper off Phenibut?+
Yes. Phenibut should be tapered with a prescriber who can adjust the plan, authorize the smaller doses, and watch for problems. Subside builds the schedule and tracks how you feel, but it does not replace medical care.
