I Got One Of My Tooth Extracted As It Was

I got one of my tooth extracted as it was creating problem and Dentist only advised and extracted.I have blood pressure and diabetis which are controlled by medicines and the dentist knew it,After extraction the wound created was treated with ice water and cotton pressed on to it. The oozing of blood very slowly was continuing even after keeping the wound pressed for more than an hour,The Dentist was reported when she prescribed one capsule of Pause 5oo.The bleeding has stopped. I had good sleep but feel little weak. Is it due to effect of Pause 500 ?
