Dazidox is available in immediate- and extended-release formulas. Manufacturers make Dazidox as a tablet, liquid concentrate or solution.

Dosage varies between patients. Physicians typically suggest a patient take 5 to 15 mg of immediate-release Dazidox every 4 to 6 hours as needed for pain. Doctors prescribe an initial dose of 10 mg of extended-release Dazidox every 12 hours and increase the dosage as needed.

A pediatrician will determine the best strength and dosing schedule for a child.

The consumer should take the immediate-release formula of Dazidox only when needed for pain, so missed doses are not an issue for these patients. Those who use the extended-release formula of Dazidox should take this medication every 12 hours, even in the absence of pain. If an extended-release user misses a dose, she should take the missed dose as soon as possible. If it is nearly time to take another regularly scheduled dose, skip the missed dose and resume the normal schedule. Do not double up on doses in an effort to catch up.

Measure each dose of liquid Dazidox with a special dose-measuring spoon or cup. Do not use a household tablespoon to dispense liquid medicine, as this increases the risk for dosing errors and overdose.

If you have been taking Dazidox for a long time, or have been taking high doses of this opioid, you may suffer withdrawal symptoms when you stop taking the medication. Try weaning yourself off by increasing the amount of time between doses.

The active ingredient in Dazidox, oxycodone, binds to the receptor cells in the brain and nervous system in a way that changes how the brain perceives pain. Oxycodone also acts directly on the cough center of the brain to reduce the urge to cough.

Recreational users target Dazidox for the euphoric effects associated with oxycodone. The DEA reports oxycodone abuse has escalated dramatically in recent years, even among school-age children. Abusers use diversion tactics, like placing bogus call-in prescriptions to pharmacies, altering prescriptions, theft and illicit purchases from the internet, to gain Dazidox.

Oxycodone pills are the most frequently abused form of the opioid; pills are often taken with alcohol to maximize effect. There is increased potential for abuse by a significant segment of the population largely because this drug is widely available to people of all age groups and is viewed as generally safe by the medical community.

Oxycodone carries a high risk for opioid dependence and addiction requiring treatment.

Withdrawal symptoms occur if you have developed a dependence on Dazidox and suddenly stop taking the medication. Withdrawal symptoms may be severe enough to prevent detoxification without medical intervention. Withdrawal symptoms usually begin six to twelve hours after your last dose and peak 24 to 72 hours later. These symptoms are very unpleasant and typically last five or more days, with the worst symptoms appearing on or about the fourth day.

Withdrawal symptoms include:

  • Chills
  • Depression
  • Diarrhea
  • Dilated Pupils
  • Fevers
  • Insomnia
  • Intense Cravings for the Drug
  • Irritability
  • Muscle Aches
  • Nausea or Vomiting
  • Runny Nose or Eyes
  • Sweating
  • Yawning


Substance abuse programs usually include detoxification from the effects of Dazidox and behavioral counseling to help individuals learn how to live without opioids. Rapid detox is a humane way to get through the peak discomfort associated with withdrawal. During rapid detox, board certified anesthesiologists administer a combination of sedatives and anesthesia, so that you sleep while medical professionals cleanse dangerous opioids from your system. You awaken refreshed a few hours later, unaware of the unpleasant withdrawal process associated with Dazidox. Other types of treatment plans are effective, whether you choose an inpatient facility or an outpatient program. Consult with your physician to find out the most effective treatment plan.
