Effectiveness
How Darvon Affects PatientsPropoxyphene is a synthetic drug similar to methadone. It works by attaching to the same receptors in the brain as opiates, which makes a person feel less pain. Propoxyphene does not help reduce coughing or fever.
How Darvon works in the bodyPropoxyphene works by interacting with special receptors in the brain and central nervous system. These receptors, called OP1, OP2, and OP3, help regulate pain signals in the body. Propoxyphene primarily affects OP3 receptors, which help decrease the activity of certain nerve cells, preventing them from sending pain signals. This helps to reduce pain and discomfort. Propoxyphene also affects other receptors which help to reduce the release of certain neurotransmitters, including substances that are involved in inflammation and stress. Finally, Propoxyphene helps reduce neuronal excitability by closing certain voltage-operated calcium channels and opening others,

10/12/2010 Unfortunately, this medication did not do much for me. I have a lot of back problems and this didn't help alleviate any pain.

3.7Patient Review
6/6/2010 The primary effect I experienced while taking this medication was intense hallucinations. It provided very little pain relief, which is why I was prescribed it in the first place. I quickly returned it to my surgeon and got a replacement within the week.
3Patient Review
4/6/2010 I took this medication for knee and hip pain, but it barely did anything. I accidentally took two pills, and there was still no significant change. The only side effects I felt were flushness and slight dizziness.
3Patient Review
2/1/2011 Unfortunately, this medication severely impairs my vision to the point where I can't read. Additionally, it gives me excruciating abdominal pain that feels like cramps but much worse.

12/24/2009 I use this to manage my chronic pain from spinal issues, fibromyalgia, and it works better for me than Oxycontin did.
1Patient Review
7/5/2010 Roxicodone 30 mg blue tablets have been the most effective treatment for my back problems. I would highly recommend them to anyone with similar issues.
1Patient Review
11/26/2010 I've been taking Darvon for migraines for over 50 years. It's not a cure-all, but it does help significantly reduce the pain most of the time. I take oxycodone when the pain is really bad, but that comes with its own set of problems. People need to be more careful and understand how their bodies react to drugs before taking them.
