Treats severe pain.

Duragesic (fentanyl) is an excellent pain reliever, but should only be used by people who've tried other opioid pain medications and still need more relief.

4.2/ 5 average rating with 84 reviewsforfentanyl
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.

Upsides
  • Duragesic (fentanyl) is stronger than morphine, works quickly, and doesn't cause as many stomach problems.
  • It's available in many dosage forms, including a patch, injection, film, nasal spray, and lollipop.
  • The Duragesic (fentanyl) patch provides long-term pain relief and lowers the number of times you need to take pain medications each day.
  • 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.
Downsides
  • Duragesic (fentanyl) isn't for everyone. It's a really strong pain medication and taking too much can be deadly.
  • The patch doesn't provide quick pain relief.
  • Often causes drowsiness and constipation. If taking long-term, use a stool softener.
  • Shouldn't be used by people with breathing problems (like asthma and COPD), a slow heart rate, or are elderly.
  • 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.
