My cat was being dosed with 16.2 mg of phenobarbital, using a pill whose gross weight was just over 100 mg. This tablet was so small it made a candy button look like a grapefruit by comparison. It turned out that she was being over-prescribed by 25%. That meant I had to take a 29 mg portion out of the tablet, then split the rest. Using the scale and an exacto knife, I was able to do just that, and kitty's blood tests improved in short order, and she's her old self.
And if you're wondering why I couldn't just use the liquid form of the medication, watch the youtube instructional videos of how to give a cat a liquid medication. Many of them begin, "If at all possible, get someone to help you".
After I bought this unit and was waiting for it to arrive I did some added research on its accuracy and was initially bummed out that it probably would not work..... but it did!
Here is what I was trying to do. I am ramping down off of a long duration use of prednisone. I am towards the end of that ramp and am trying to cut the dose by 1-2mg per day. The pills I have are 20,10, and 5mg. So I have been cutting them and eyeballing how big the cut piece was to go from 10 to 9 to 8 to 7 etc. It was kind of inaccurate.
This unit does not really show what the accuracy is but its resolution is .001g or 1 mg. If you read the reviews, the readings in the <1 gram are all over the place. So I thought this will not work.
But I found a way...
First..... you should know (I did not know) that a 10mg pill does not necessary weight 10mg..... it may actually weight as much as 200mg. That is becuase of all of the fillers and coatings in a hard pill. The 10mg is actually the dose weight of the active ingredients??? You don't have to know what % is active but its good to know so you don't freak out when you try to weigh your pill.
Next... I already know by eyeballing the pills what the approximate dosage should look like. I would not suggest trying this unless you can do this. In other words do not wholly trust the scale.
Next.... calibrate the unit (instructions in manual)
Next... You should know that weight measuring devices work best in about the middle of thier range. So turn the unit on.... let it warm up for about a minute. Add the 10g standard weight. It should read 10.000g, right in the middle of its range.
Next add a whole pill. Say you want an 8 mg dose. Add the 5mg pill. In my case it then read 10.100g (the pill wt was actually 100mg or 20 times the stated dose). I know I want 3 more mg. So I cut some of the 5 milligram pills into rough quarters (but really all a bit different). I know now that for a 8mg dose I need to see it read about 20 times that or 160mg or on the gauge 10.160g. I put in different pill quarters till I get a reading close to this.
It turns out that the scale is very repeatible and I can pull that quarter piece off and put it back on several times and I get about the same reading each time.
You can tare the 10gm weight out but I like to see everything being weighed.
Again do not do this if you do not allready know roughly what your cut dose should look like. Also I have read that the actual dose weight of a pill can be 5-20% of the actual total pill weight. So you will have to figure that out for your own pills.
I bought this same model in 2010 and it was better, but it just lasted for about 2 1/2 years of use before it suddenly died.
