My father is a diabetic whom takes about 8 different pills a day. Not all for his diabetes.He was bitten by a poisonous spider about a week ago. I'm worried that he is over-medicaded.. He received 1 shot coctailo for the spider bite, then got a flu shot the same day along with a B12 shot. His doctor also has him taking valium, one at night & .5 in the morning.. What do u recommend?
