Opioid Potency Comparison
Medical Editor: Benjamin C. Wedro, MD, FAAEM
Narcotic medications vary in their potency. Each drug has a different prescription range of effectiveness and the number of milligrams in the dosage is not an indiucation of how strong the emdication might be.For example, the dose of hydormorphone (dialudid) needs to be only 1.5 mg to equal the effectiveness of 10mg of morphine.
In general medications given intravenously or by intramuscular injection will have a quicker onset of action than medications given orally.
IV = intravenous
Routine dosage equivalent to Morphine 10 mg IM or IV
