What is Darvon?
Darvon, also known as propoxyphene, helps treat mild to moderate pain. Propoxyphene belongs to the class of drugs known as narcotic pain relievers.
Avoid taking propoxyphene if you have a history of suicidal thoughts or actions. Do not take propoxyphene with a sedative (such as Valium or Xanax), an antidepressant, and alcohol.
Propoxyphene has the potential for drug abuse, so do not use it without prescription. Keep this drug in a safe place where no one else can access it. If you are taking propoxyphene, do not drink any alcohol. If you combine alcohol with a narcotic pain reliever, dangerous side effects or death can occur. Check the labels on your food and medicine to make sure they do not contain alcohol.
Do not take propoxyphene more than prescribed. Tell your doctor if the medicine is not working as well as it used to in relieving your pain. Propoxyphene has side effects that can make it difficult to think or react. If you drive or do anything else that requires you to be awake and alert, be cautious. If you stop taking propoxyphene suddenly, you may experience unpleasant withdrawal symptoms.
