@chai2,
a few decdes ago, someone poisoned some headache remedies with cyanide capsules. I believe two people died before the entire lot was removed from store shelves.
If one pill is a poison capsule and its in the dosage mix. You may be playing "Scrip Roulette"
Id do like the above posters say. Cant hurt and you can give hell to the pharmacist for selling you the prescription. Is there an odor of almonds ? coming from the jar?
(Course some relly deadly stuff like Na Flouro -acetate (Compound 1080) has no odor (NOR any antidotes)
re you scared enough to take it back now?
