Several years ago, my then husband was prescribed Dilaudid for pain relief from a hernia surgery. He took only two doses of this medication as prescribed and I honestly thought he was going to lose it on me. It made him nearly paranoid. His eyes were dilated, he kept looking back and forth across the room like he was afraid someone was after him and he was shaking all over. I knew then he could not take this medication. So we stopped it right away and called the doctor for a different prescription. Does this sound like an allergic reaction or is this the effect this narcotic often has on some people?
