Is 80mg of Dilaudid ok to take in a 24 hour period?

No! Dilaudid is a very strong drug.... 80 mg in one day would kill a horse. Even 8 mg in a 24 hour period is a very high dose (if we are talking IV form). Pill form is less strong and can be taken in a higher mg dose, but nothing CLOSE to 80 mg. An average dose in pill form would be 2-4 mg every 4-6 hours. Anything more than this should not be taken unless the person has a very high tolerance to narcotics.
