What is the scale of pain killers from least potent to most potent?

I disagree and digress concerning all meds like we have all been made to do. Lets let our congress decide our patients pharmacological needs.
They are so much more qualified to make those tough decisions. They have done a bang up job blaming every over dose (or most) on the Physicians who write prescriptions. 30 to 70,000 people a year die from opiate overdoses depending who you ask. The concerned congress stepped in to save lives, at least that is what they would have all believe. That's what my congressman of PA told me.
Opiates can and do kill people if they are abused.

480,000 Americans die of tobacco every single year. Four hundred eighty thousand! Congress has always known the tobacco death figures. Every year they pocket millions of dollars of hush monies from big and little tobacco and our Americans continue to die horrible painful deaths and congress keeps pocketing and pocketing and pocketing. We have an opiate problem. Stats are based on deaths. Who's winning?

Dzoo, right on again!! Some people prefer one pain med over the other, so it really isn't what is stronger, it's what works best for you. FI, I could take a bottle of dilauded ( I wouldn't ), and it wouldn't affect me at all. My hubby has to take hydrocodone, and oxycodone doesn't affect him at all. It really depends on the person, and their genetic make up.

Did I see methadone on the list? I have no idea where that falls, though i know that it is fairly potent.

you can go by the drug class schedule.In my opinion and remember this is just my opinion im goin to list the most common prescribed pain meds from least to greatest in strength starting with tylenol3 and 4 then hydrocodone 2.5mg 5mg 7.5mg and 10mg then oxycodone comes in numerous strengths and different names some have fillers some dont they come in percocet 5mg 7.5mg and 10mg there is roxicodone 15mg 30 mg then oxycontin 10mg 20mg 30mg 40mg 60mg and 80mg some of that may have changed since they changed the formula then there is methadone 5mg 10mg and it used to come in 40mg wafers.and the mort potent of all is fentanyl patches wich comes in several strengths it comes in a sucker form and pill form for breakthrough pain.there are a few I didnt mention like tramadol its non-narcotic but helps some people and morphine and dilaudid.I hope this was helpful
