Hydromorphone
"I was in the E.R. for pain associated with condition causing kidney stone {1 in each kidney}. I am severely allergic to all anti-emetic drugs (anti nausea/vomiting drugs) but I required a potent pain killer. I was given Dilaudid by i.v. having never been on anything stronger than Percocet pills the doctors were afraid that I'd become very nauseous and vomit profusely and unable to be treated for nausea. To my relief it did the trick! I only vomited once, was prescribed hydromorphone 2mg. NO SIDE EFFECTS! I was to sick to see the beauty in everyday life, until now!"
