Fentanyl side effects?

You might have to use the 12 mcg and take something else for the break though pain and kind of work your way up to the 25 mcg. It might take awhile to get use to the 25's, but if you have to drive I would stick to the lower dosage. My dad uses the 25 mcg and has to take lortab for the break though pain cause the 50 mcg is too strong and he will be walking from the living room to his bedroom and just about can't make it cause of weakness and he also sleeps a lot more on the 50's (he sleeps a lot anyway). Talk to your dr about maybe something to go along with the 12's so you can function.
