Okay...I know I was called a hypochondriac in here yesterday but I don't care. I have a question. I think it's legitimate. Are there any Pharmacists or Pharm Techs in the house?

I just had to cut a 30 day supply of my sons Guanfacine 2 mg tablets in half to give to th youth shelter for him because they won't do it there. I breastfeed my baby. I know when I cut the pill with the cutter, powder gets into the air. Do you think I may have inhaled a dangerous amount of powder while cutting those to where I shouldn't breastfeed for the rest of the day, or do you think I will be fine? I ask because it's so much better to be safe than sorry.
