Fentanyl is about 80-100 times stronger than intravenous morphine. :
fentanyl is 50 to 100 times more potent than morphine. The wording is extremely important. 100mcg/hr of fentanyl is a patch and before you can compare it to morphine you have to convert it to the same dosage.
100mcg/hr of fentanyl is about a daily dose of 2.4 mg of fentanyl. The conversion then becomes 2.4 mg of fentanyl = 200 mg of morphine. You can't compare two different measurement sizes when doing this type of math and just apply the math directly to the differing measurements, this is grade school math. They have to both be mg or both be mcg before you apply the math.
Fentanyl is 50 to 100 times more potent than all types of morphine not just intravenous. Fentanyl is more potent than Hydromorphone/Dilaudid which is only 5 to 8 times more potent than morphine. Fentanyl is the most potent legal pain medication on the market. If you are thinking of taking this drug or already taking it do not go by the math of the user before my name or any user here.
Please consult a doctor to find out if you need narcotics and if Fentanyl is right for you. I have been on it three years and I have been trying to find a way to get away from it. Think about it though if you or others attempt to use the horrible math done by the previous user than you could have suffered withdrawal if you already take narcotics or god forbid overdosed somehow. It is the doctors job to help you decide your dose with your input on what works.
I have just talked to my pharmacist at the VA in MPLS, MN about changing my 75 mcg patch to long term oral morphine. My patch says it has 12.6 mgs of Fentanyl in it which is 4.2 mgs per day. She told me that the equivalent to morphine would be 160 mgs - which proves your answer correct since 200 times .75 equals 160. I am not sure how you came up with your answer though so I personally do not know how the answer is derived at. I started with 75mgs of methadone per day but they took me off because of a low heart rate. I have always had a low heart rate and the methadone worked well for my pain and the patch did not - so that now brings me to trying the morphine. I cannot see how it will be different. Thank you for your answer. Since my doc seems angry with me because I augmented my patch with some leftover methadone once, I just wanted to verify the equivalency with someone else.

∙ 14y agoThe equivalence is approximately 100 micrograms (mcg) of Fentanyl to 10 milligrams (mg) of Morphine, so 75mcg is equivalent to 7.5mg's of Morphine.

Is morphine sulfate ER similar to fentanayl?
Although both morphine and fentanyl are opioid painkillers, there are significant differences between the two, both in chemical structure and effects. Fentanyl is much more powerful and shorter acting than morphine (although it is not active if swallowed), and thus the dosing schedules/mechanisms are very different.
