Head-to-head comparisons of medication uses, side effects, ratings, and more.

Treats arthritis pain and swelling.

Zorvolex (Diclofenac) is an okay medication used to treat pain and swelling caused by arthritis. However, because of the risk of heart attack, you should limit the amount you take.

Treats moderate to severe pain.

Percocet (Oxycodone / Acetaminophen) is the strongest prescription combination pain medicine for as needed pain relief, but make sure you don't take too much acetaminophen (Tylenol) to avoid liver problems or death.

  • Clinical studies show that Zorvolex (Diclofenac) is better at relieving arthritis pain than acetaminophen (Tylenol).
  • Can be used as needed to treat pain and swelling.
  • Available as a generic.
  • 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.
  • You should avoid alcohol while on Zorvolex (Diclofenac) since it can increase your risk of stomach issues.
  • If you're taking it on a regular basis, you'll need to get labs done to make sure your liver and kidneys aren't being affected.
  • 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.
