Upsides
  • Combination pain medicine with an opioid component (oxycodone) and non-opioid component (acetaminophen or Tylenol) that takes advantage of different modes of pain relieve in a single pill.
  • Provides quick relief for moderate to severe pain to improve quality of life.
  • Generally considered stronger than Norco or other combination pain medicine for treating pain.
  • Good for as-needed, short-term use, but may be helpful to manage more long-term pain problems if used at the appropriate doses and intervals.
  • Lower rates of misuse compared to pure opioid medicines.
  • Can help you fall asleep easier.
  • Provides longer relieve for moderate to severe pain to improve quality of life.
  • Good for chronic pain that requires around-the-clock relief.
  • Might have fewer side effects than other opioid pain relievers.
Downsides
  • Dizziness and drowsiness is common, but your body may adjust.
  • Everyone will get constipation - always stay hydrated and take stool softener or stimulant on days you're taking Percocet if you need.
  • All opioid containing medicines have the risk of physical dependence and possibility of withdrawal when used long-term.
  • The non-opioid part of Percocet, acetaminophen (Tylenol), has a high risk of liver failure and death if you take more than the maximum daily dose. Be very careful.
  • Relies on the users to be aware of how much acetaminophen (Tylenol) they are using since it is a very common ingredient in many prescription and non-prescription pain medicines.
  • Avoid alcohol.
  • Doesn't work for as-needed or quick pain relief.
  • Dizziness and drowsiness is common, but your body may adjust.
  • Everyone will get constipation - always stay hydrated and take stool softener or stimulant on days you're taking Ms Contin (Morphine Sulfate) if you need.
