the way mine are, yes you can.

i've broken the .5 in half and then broken that in half and taken the quarter, then 1/2 an hour later taken the other quarter when I was going thru really high anxiety about taking it.

of course, that small a dose probably doesn't help with symptoms, but it helped my anxiety about taking them. the next time i was able to go ahead and take the half of the .25.
