Acetamenophine is an analgesic drug, used to treat headaches, Arthritis, etc., and also to reduce fever, often as an alternative to aspirin
It is not strong, although a good pain reliever. 5 is the percocet (oxycodon) and 325 is Acetaminophen (Tylenol). Oxycodone is one of your stronger pain medications, so take with food to prevent a queasy stomach.
The morphine. What you're comparing is 10mg of oxycodone vs 60mg of morphine. Mg by mg oxycodone is a bit stronger than morphine, but 60 mg's of morphine would be about equivalent to 40 mg's of oxycodone, which would be four of the 10/650 pills. I don't have a conversion chart in front of me, but this is a pretty close estimate. Even though 4 of the Percocet would be equal to about 60mg of the Morphine you dont want to take the Perocet for a long period of time because it is only 10mg of oxycodone and 650mg of Acetominophine which you are told not to consume to much of because the liver damage it will cause.
When it comes to medications like roxicodone, oxycodone (same thing, roxi is brand name), hydrocodne etc the length of time in system varies upon the persons metabolism. However, a good rule of thumb is about 3-4 days to be completely out of your system for the purpose of urine analyst. If you are wondering about how long the 'effects' of the drug last - again depends on the person and metabolism - but the average time the effect of the drug last is anywhere between 4-8 hours. This class of medication, especially the instant release oxycodones such as Roxicodone 15, 30 etc are especially addictive and should be used exactly as prescribed. One of the reasons this drug is so addictive in nature is how fast the effects come on and the euphoric feeling goes away faster than the medication works on the pain. In other words, you may not 'feel' the drug working - even though it still is working on the pain. The euphoric feeling may be gone. This also makes it rather dangerous as people do tend to abuse this medication more so than others and it is more addictive than the "Extended Release" Oxycontin - despite it's bad name, is no where near as addictive if and only IF taken exactly as prescribed. I am *NOT* a doctor or a pharmacist and not attempting to portray myself as one. However, I do have extensive knowledge of short and long term pain medications as well as many others through years of research. Cheers Sandy aka Axollot
