Has anyone had issues with withdrawal symptoms coming on suddenly? I know the Opana ER doesn't last 12 hours (even my doc warned me this was the case) but this latest batch of opana seems to poop out & give me old sweats about 4 hours after taking it.
I've been on Opana ER, 20 mg 2x/day for a couple of months. It's my 2nd experience with long-acting opioids (1st was Oxycontin MS, quit after 10 days due to gluten issues). I have noticed variability in Opana's pain control --pain will go from 4-5 to 7-8 in an hour or two. I wasn't too surprised, since years of experience with opioids have shown them to be pretty unreliable on pain control generally...tho better than nothing!!
I sorta expect pain to come back early, but until this refill I've never had withdrawal symptoms unless I've not taken any Opana in at least 20 hours.
A couple years' experience on fentanyl patches showed about a 15% failure rate with them; "3 day” patches that had me in withdrawal 6-18 hours after switching to a new patch (along with massive pain increase, of course).
Anyone familiar OpanaER fade-out?
