Can someone please explain what this is? I’m needing help with tapering

Hi Freespirit123,

 

I'm not a moderator here, but I can explain the calculator.

A taper - the type recommended on this forum - is a decrease at 10% of the current dose, every three or four weeks.

In other words each dose is 10% less than the one before it, so the actual amount you go down by gets less and less.

Technically-speaking it never reaches zero,

but you'll be choosing your own taper, built up of different rates and/or doses.

I'd rather let a moderator pick up beyond this point in the explanation.

 

This calculator accepts a starting dose, and an end dose.

The start dose is the dose you're on now.

The end dose is not necessarily the very final dose.

 

In fact in almost every case it won't be the final dose, since you won't know what that is until you're close to it.

So the end dose can be set according to how much supply of the medication you have or want to buy, just as an example.

You might just want to set it to one tenth of what you're on now to see the figures.

 

Those figures it outputs are the doses. There's no taper period implied here.

You will choose that, and it may be 3 weeks or 4 weeks or something else.

 

If, say 4 weeks, then you would need 28 doses of each of those amounts.

(a bit more actually because you may need to reinstate the previous dose in a hurry if it's too fast)

 

Days times dose.

 

For example:

28 x 1mg
28 x 0.9mg
28 x 0.81mg
28 x 0.729mg

 

To keep track of your taper, add the amounts to a calendar, or copy and paste the output into a spreadsheet.

Then stretch / repeat each amount out to the number of days per taper-period.

 

Hope that made sense.

You’re amazing Dr Mussy, this is so needed. Withdrawal exacerbates my normally mild dyscalculia so I always found making a tapering schedule a bit daunting. Thank you so much, you’re a hero!

Tiggy and I find it hard enough:

  • keeping track of her supplies
  • deciding what to do next (down, hold, up)
  • working out the doses
  • making sure there are enough backup doses for reinstatement or holding
  • ordering the prescription
  • getting it sent to the compounding pharmacy

She's been impaired, but thankfully has been fine at managing the times and durations,

whereas I seem to be more about quantities.

Y to her X (why to her ex?)

 

So it certainly has crossed my mind that someone doing this on their own could use some help.

Beautiful job, DrMussy.

 

Where you jump off your taper depends on your symptom pattern. One thing you can count on: It will be less than 1mg.

I've just posted this to help one of the members so I thought I'd post it here for others:

 

 

An easy way to work out your next taper dose (a 10% reduction) is to multiply the current dose by 0.9 (if making a 5% reduction multiply by 0.95).  This will be the dose you need to take.  If you want to double check your calculations you can also multiply the dose by 0.1 (for a 5% reduction multiply by 0.05) and then deduct that from the previous dose.

 

Current dose = 20mg

 

1st reduction:     20mg x 0.9 = 18mg       double check:     20mg x 0.1 = 2mg   so   20mg - 2mg = 18mg

 

2nd reduction:    18mg x 0.9 = 16.2mg   (if you can't easily measure 16.2mg round up to 16.25mg or 16.5mg - NOTE always round up)

 

 

Please note that the next reduction needs to be calculated on the dose you took:

 

3rd reduction (choose one of these doses):

 

16.2mg x 0.9 = 14.58mg         (eg round up to 14.6mg or 14.75mg)

 

16.25mg x 0.9 = 14.625mg    (eg round up to 14.75mg)

 

16.5mg x 0.9 = 14.85mg         (eg round up to 15mg)

 

 

Remember that the next reduction needs to be calculated on the dose you took on your 3rd reduction.

Thank you so much Dr.Mussy :-) :-) I was trying to figure out the amount to taper; after I realized it wasn't starting dose 100mg, 90, 80, 70 wasn't 10% taper lol.

Plans are most certainly under way to make it into "a proper app", amongst other things.

Not that it'll be that hard to do, just that it's lower on the list of priorities,

one of which is rebuilding the code base, which will affect it if made into an app.

For now, a bookmark in your phone's browser is your best bet.

I have a mg. scale, and know how much one 10 mg. Paxil tablet weighs. I can easily figure how to cut it by 10%, then 10% of that dose, and so forth. But the site asks that we report our tapering progress in mg.s. How do I covert pill weight back  to mg.s?  I’m bad at math. Can anyone help me with this? Thank you!

You would use the same calculation as you used for the dose weight. For a 10% reduction:

10mgai X .9 = 9mgai

9mgai X .9 = 8.1mgai

 

For the weight of the actual dose, from the scale, we like to use the sufix mgpw, milligrams pill weight (i.e. 125mgpw)

For the strength of the dose we like to use the sufix mgai, milligrams active ingredient (i.e. 9mgai)

 

This makes it a bit easier to follow which measurement is being talked about.

 

Hope that helps.

I've tweaked the taper calculator to handle floating point numbers.

 

Click the three-dot symbol at the bottom

Set Taper Percent to eg. 2.5

Hi Blandell,

 

Thanks for pointing this out, however it seems to work fine for me.

 

I can type 5 into the field (without typing "%"),

and I can click the little ↕︎ arrows, which adjusts it by 0.1 on each click.

 

Could you elaborate on the issue you are experiencing?

 

Many thanks,

DM

Thanks Blandell,

I'd like to fix this so it works for everyone.

Could you let me know which web browser you are using?

(eg. Chrome, Firefox, Internet Explorer, Safari, Opera..)

Perhaps you are using your phone or tablet.

No arrows on mobile devices. On my todo list..

Arrows missing in some web browsers

Input spinners - the little adjustment arrows - don't appear in Safari for some users.

Continuing from this thread.

Ok, I see it now, and some other issues.

Except for the input field in question where the spinner arrows don't appear,

in Safari they appear all the time in other input fields.

 

The spinners are supposed to be hidden until clicked on all browsers.

Firefox has some issues too, which I will see to after these have been sorted.

Will look into these and report back here.

Here is the calculator we built-  this micro-dose calculator includes the 2 week hold per Brassmonkey's slide recommendations...

Hi Surfchick-- The calculator looks good and my first quick test was fine with one exception.  The year column only indicated which page you were on and not the time spent to that point.  My test of  40mg at 10% showed a taper length of 2 years when it should have been more like five to five and a half years. This could be very misleading for people trying to make plans.

Ok i see it only goes down to .09mg.. 

Feel free to delete the post, im not sure why its stopping at .09

My mistake, I entered the percent of taper wrong. Never mind.  It is showing that the taper will take seven plus years to complete, which mathematically is correct, but in practical terms not doable.  The physical limitations of making the reduction below 1mg make it very hard to complete the taper in this manner. It may be an idea to add a note about this and truncate the program at some point.  I'll take more of a look at it.  There is some discussion on this problem on the Brassmonkey Slide Method of micro tapering thread.

 

BTW I do like the calculator and think it will be very helpful.

OK ill talk to my husband, he built it for me, and to share. This is just the first draft :) He's working on an app as well for itunes this next year. 

It is a great way to get started!
