Treatment SummaryDextropropoxyphene is an opioid painkiller that was manufactured by Eli Lilly and Company. It was used to treat mild pain, as well as coughs. Due to the risk of overdose and deadly cardiac arrhythmias, it was removed from the market in many countries. Dextropropoxyphene is made up of two isomers, dextro- and levo-; only the dextro-isomer has any analgesic effect, while the levo-isomer only exhibits a mild cough-suppressing effect.

Effectiveness

How Propoxyphene Hydrochloride Affects PatientsPropoxyphene is a synthetic drug similar to methadone that works as an opiate pain reliever. It helps to block pain signals so that the person taking it does not feel pain. Propoxyphene does not help with coughing or reducing fever.
How Propoxyphene Hydrochloride works in the bodyPropoxyphene works by directly interacting with your body's opioid receptors. It primarily binds to OP3 receptors, which are responsible for modulating the activity of certain proteins. When these proteins are activated, they reduce the amount of substances like dopamine and acetylcholine that your body releases. They also reduce the activity of nociceptive neurons, which helps to reduce pain. Propoxyphene also works to hyperpolarize neurons, making them less likely to fire and reducing nerve excitability.

Propoxyphene Hydrochloride for Pain
This medication is effective most of the time, but I have to take more of it in winter. If I do anything that's even a little bit more strenuous than walking, I have to take the full prescribed amount.

Propoxyphene Hydrochloride for Pain
I've been using this medication for 20 years after my skull was crushed and it's really helped me live a normal life despite my injuries. I'm now 68 and the government is trying to take it off the market, which would be devastating for me. It's hard enough to find a place that will fill my prescription as it is.

Propoxyphene Hydrochloride for Pain
Propoxphene was the only pill that worked for me. Unfortunately, some people died from mixing it with alcohol, so now the FDA has banned it. I'm in a lot of pain from two back surgeries and arthritis, and this was the only thing that helped.

Propoxyphene Hydrochloride for Pain
I've been using this medication for my arthritis and joint pain for years now, and it's always worked well for me. The drowsiness is a bit of a downside, but that seems to be common with narcotic pain medications.
