From what i am aware of, my anastrozole will come as a capsule and not a tablet. so how to split or reduce that?
I buy empty capsules, open the ones with the medications, dump some of the power into the empty then recap.
You can also dump the powder onto a plate, divide it visually into an equal number of piles and then scope up with an empty capsule.
You can also buy a very accurate scale (there are some pretty inexpensive ones on Amazon) and weigh out equal piles.
These techniques might be good enough for what you need.
