Oxycontin (Oxycodone)

Prescription only

Methadose (methadone)

Prescription only
Treats severe pain.

Oxycontin (Oxycodone) provides options for treating both short and long-term moderate to severe pain, but no matter how long you take it, you’ll need to watch out for constipation.

3.8/ 5 average rating with 1241 reviewsforOxycodone
Treats severe pain or drug dependence.

Methadose (methadone) is a cheap and effective treatment for severe chronic pain, but has serious risks for fatal overdose and drug dependence.

Upsides
  • Oxycontin (Oxycodone) immediate-release (short acting) works best for “as needed” or “break-through” pain.
  • Long-acting tablets are good for chronic pain that requires around-the-clock relief.
  • Can have fewer side effects than other opioid pain relievers.
  • Generally considered to be stronger than morphine.
  • Available as a cheap, generic version.
  • One of the stronger opioid medicines for treatment of severe pain.
  • Can also be used to treat opioid dependence as part of a complete recovery program.
Downsides
  • Dizziness and drowsiness is common. While taking this, it’s best to avoid alcohol.
  • You’ll need to take the immediate-release for a few weeks before you can be switched to the long-acting formulation. It’s not safe to start taking the long-acting one if you've never taken an opioid pain medicine before.
  • Everyone will get constipation, so it’s best to stay hydrated and take a stool softener while on Oxycontin (Oxycodone).
  • Long-term use will likely cause physical dependence.
  • Need be weaned slowly off the medicine after using it longer than two weeks.
  • Methadose (methadone) can cause slowed breathing, coma, and death from overdose, especially if mixed with alcohol, sleeping pills, or muscle relaxants.
  • Constipation is a common side effect of Methadose (methadone) and you might need laxatives or stool softeners.
  • Not a good option for short-term pain relief.
