Physicians prescribe Darvocet to reduce mild to moderate pain, with or without fever. Darvocet is available in tablet form to be taken by mouth. Darvocet is a combination of propoxyphene, a narcotic pain reliever, and acetaminophen. Propoxyphene works by binding to pain receptors in your brain in a way that changes the way you perceive pain. Acetaminophen is a mild pain reliever and fever reducer that increases the effects of propoxyphene. Acetaminophen blocks the production of prostaglandins, a substance that causes pain.

Learn More About Darvocet Side Effects
Darvocet works by stimulating your brain's opioid receptors; overstimulation of these receptors may cause seizures, depression of your central nervous and respiratory systems, and can affect your mood and thoughts. Do not take Darvocet if you are allergic to it or are having severe bowel problems. Darvocet can increase your risk of bleeding if taken along with anticoagulants. Do not drink alcohol or take other pain medications with Darvocet, as this increases your risk for serious injury or even death from overdose. There have been numerous cases of accidental and intentional overdoses using propoxyphene alone or in combination with other drugs or alcohol. Death from Darvocet overdose can occur as early as an hour after taking the excessive dose.
If you have been taking large doses or have been on Darvocet a long time, do not suddenly stop taking Darvocet unless directed to do so by your physician, as an abrupt cessation may cause unpleasant withdrawal symptoms. Pregnancy and breastfeeding warnings
More Warnings About Using Darvocet

Some people are unable to metabolize Darvocet, making it an ineffective choice for pain relief for these people.
Some drugs may interfere with Darvocet, preventing the medicine from providing pain relief. Do not use Darvocet if you have used MAO inhibitors in the previous two weeks, as Darvocet may react with residual MAO inhibitors in your system. A dangerous drug interaction can occur if you take Darvocet before MAO inhibitors have left your system.
More Drug Interactions
In the United States, Darvocet is available in tablets with strengths ranging from 30 mg to 650 mg. The usually dosage is one to two tablet every four hours as needed for pain. The dose should be adjusted according to the patient's size, severity of pain and the patient's response to the medication. Darvocet A-500 is 100 mg of propoxyphene napsylate with 500 mg of acetaminophen. Darvocet N-50 contains 50 mg propoxyphene and 350 mg of acetaminophen. Darvocet N-100 contains 100 mg of propoxyphene and 650 mg of acetaminophen.
Since Darvocet is prescribed to be taken on an as-needed basis, people who have used Darvocet for a very short amount of time should be able to miss a dose without any problems. However, Darvocet is highly habit-forming; people who have used this opiate for a long period of time or for recreational purposes may suffer unpleasant withdrawal symptoms soon after missing a dose.
Darvocet overdose is a serious and potentially life-threatening situation. Contact your local emergency room immediately if you suspect that or someone you know has taken an overdose of Darvocet.
Overdose symptoms may include:

Slowly decrease your daily intake of Darvocet, whenever possible, to avoid withdrawal symptoms. These withdrawal symptoms set in quickly and you may have trouble managing them on your own. If you cannot tolerate the withdrawal process through slow dosage reduction, there are many treatment options available, including rapid detox. Withdrawal symptoms include:
There is a high risk for mental and physical dependency and addiction to Darvocet. Using Darvocet as prescribed for long periods of time can cause you to develop a tolerance to the medications, which means you will have to take increasingly larger doses to acquire adequate pain relief. Talk with your doctor if Darvocet no longer controls your pain effectively, as you may be building a tolerance to it.
Taking Darvocet for recreational rather than medicinal purposes can result in a dry mouth, decreased appetite, constipation or diarrhea, urinary problems and increased risk for addiction. Long term abuse can cause stomach pain, nausea, vomiting and even liver toxicity.

Other, off label uses for this medicine
Darvocet can be used to reduce the physical signs of addiction to other opiates but Darvocet is not effective at reducing mental cravings.
More Off-Label Uses for Darvocet
There is much controversy surrounding Darvocet in the years since it was first approved for use as a pain killer a half century ago. There have been numerous cases of adverse reaction, addiction and overdose associated with Darvocet. Opponents maintain these risks far outweigh the relatively weak pain relief Darvocet provides.
