Klonopin Taper Calculator
Generate a week-by-week clonazepam taper chart — with dates, cut sizes, and diazepam equivalents to review with your prescriber.
Klonopin (clonazepam) sits in a middle ground among benzodiazepines: it's as potent as Xanax (0.5mg ≈ 10mg diazepam) but has a much longer half-life of 18–50 hours. That longer half-life means steadier blood levels, which is why many people are able to taper clonazepam directly without crossing over to diazepam first.
Enter your total daily clonazepam dose below to generate your personalized taper chart — the tool cuts a percentage of your current dose at each step, following the exponential pattern recommended by the Ashton Manual and modern deprescribing guidelines.

What makes a clonazepam taper unique
The long half-life is your friend: levels change slowly, so you typically won't feel a cut for 3–7 days. This lag time is the most important thing to understand about a Klonopin taper — a cut that feels fine on day two may catch up with you on day five. That's why holds of at least two weeks are usually recommended before judging whether a cut was tolerable.
Clonazepam's potency is the challenge on the way down. Below roughly 0.5mg/day, quarter-tablet cuts become large in relative terms, and many people move to micro-tapering with a precision scale or compounded liquid. The calculator marks where that transition is likely to happen in your schedule.
Managing the long half-life also means dosing timing is flexible — most people do fine on twice-daily dosing throughout the taper.
How to read your taper chart
Each row shows the date a step begins, your new daily dose, the size of the cut, and the approximate diazepam equivalent. If a step feels too harsh, the standard adjustment is to hold longer, not to skip back up and down — instability often comes from changing direction repeatedly.
Print the chart (or save it as a PDF) and bring it to your prescriber. A concrete week-by-week plan is the single most useful thing you can put in front of a doctor when asking for a supported slow taper.
Frequently Asked Questions
How do I taper off clonazepam 1mg?
A common approach is reducing by 5–10% of your current dose every 2–4 weeks. From 1mg daily, a 10% first cut is 0.1mg. Because clonazepam tablets don't divide that finely, many people use 0.125mg tablets, a precision scale, or a compounded liquid to make accurate cuts. Enter 1 in the calculator above to see the full schedule, and review it with your prescriber.
How long does it take to taper off Klonopin?
With 10% cuts every two weeks, reaching a low jump-off dose typically takes around 10–12 months from a standard dose. Slower schedules of 18 months or more are common and are not a sign of failure — the Ashton Manual emphasizes that the taper should move at the speed your symptoms allow.
Do I need to switch to Valium to taper off Klonopin?
Usually not. Because clonazepam is already long-acting, most people can taper it directly. The Ashton Manual does describe a clonazepam-to-diazepam crossover for people who struggle with cuts at very low doses, since diazepam's 2mg tablets and liquid form allow finer reductions.
What is a clonazepam taper chart?
It's a table showing each planned dose reduction: the date, the new daily dose, and the size of each cut. The calculator on this page generates one automatically from your current dose using percentage-based (exponential) reductions, and lets you print it to share with your prescriber.
Why do I feel a Klonopin cut a few days late?
Clonazepam's half-life is 18–50 hours, so after a cut it takes roughly 4–10 days for blood levels to fully settle at the new lower level. Symptoms often appear on day 3–7 rather than immediately. This lag is normal and is the main reason holds shorter than two weeks can be misleading.
Sources & methodology
Equivalence values and reduction percentages follow the Ashton Manual (Prof. C. Heather Ashton, 2002), consistent with modern deprescribing guidance recommending gradual, patient-led benzodiazepine reduction and warning against abrupt discontinuation. This calculator performs arithmetic only — it is educational, not a prescription. Always work with your prescriber.
