I Have Been On Fentanyl for over 10 years 200 milagrams every 72 hours, How Hard Will WithDrawl Be And Is It Dangerous ?
Fentanyl is the most potent opioid available, however, when it comes to which opioid is stronger, much depends on the dosage. For example, a low dose of fentanyl may not be as "strong" as a high dose of morphine.
Having said that, 200 micrograms (I think you meant micrograms and not milligrams) of fentanyl is a very high dose. I wouldn't recommend trying to withdraw cold turkey from that high of a dose as it would be very difficult and could be dangerous. It's best to taper off of opioid medications gradually and under a doctor's care. There are some non-opioid medications your doctor can give you to help ease some of the withdrawal symptoms.
Also, you might want to talk with your doctor and see if Suboxone would be a good option to help you get off of the fentanyl. Here's more information on it: Suboxone: An Exit Strategy
Good luck to you!
