I could not find any information regarding the "new" regulations by DEA for Methadone. DEA is in no position to tell doctors how much and what to prescribe, that would be practicing medicine without license. DEA however, can regulate other aspects such as that prescription cannot be given for more than one month supply, and that patient has to be seen and assessed prior each prescription given, that medciation cannot be called into pharmacy.
Prescribing Methadone for pain, and Methadone for addiction is two totally different issues.
Methadone for pain is given multiple times a day and even though patient may have abuse issues if they also have pain, their pain is treated in the same manner as it would be treated for any other patient the only exception they have to be monitored more closely. Most doctors in that case would refer those patients to addictionologist.
Regarding your doctor cutting your prescription into half because of DEA regulation sounds a bit strange to me. If he is giving you methadone for pain, and even if DEA regulation came out restricting the dosage given, still you would have to be weaned off it slowly to desired dose due to withdrawal symptoms, this means your well-being is a consern. DEA regulations usually apply to new patients and with old ones you would have to wean them down to comply with regulations if those regulations existed. Again, doctors do have extensive freedom in treating their patients regarding how much and what they are going to prescribe and how they are going to wean you off.
I went to DEA site and below is copy and paste information from their site that would be of interest to you. I also included website address for you if you would like more information you could go to their site. Please let me know if you require anymore information.
Question: Can a practitioner prescribe methadone for the treatment of pain?
Answer: Federal law and regulations do not restrict the prescribing, dispensing, or administering of any schedule II, III, IV, or V narcotic medication, including methadone, for the treatment of pain, if such treatment is deemed medically necessary by a practitioner acting in the usual course of professional practice.
Confusion often arises due to regulatory restrictions concerning the use of methadone for the maintenance or detoxification of opioid addicted individuals, in which case the practitioner is required to be registered with the DEA as a Narcotic Treatment Program (NTP).
Can methadone be used for pain control?
Methadone, a schedule II controlled substance, has been approved by the FDA as an analgesic. While a physician must have a separate DEA registration to dispense methadone for maintenance or detoxification, no separate registration is required to prescribe methadone for pain. However, in a document entitled "Methadone-Associated Mortality: Report of a National Assessment,'' SAMHSA recently recommended that "physicians need to understand methadone's pharmacology and appropriate use, as well as specific indications and cautions to consider when deciding whether to use this medication in the treatment of pain.'' \35\ This recommendation was made in light of mortality rates associated with methadone.
What additional precaution should be taken when a patient has a history of drug abuse?
As a DEA registrant, a physician has a responsibility to exercise a much greater degree of oversight to prevent diversion and abuse in the case of a known or suspected addict than in the case of a patient for whom there are no indicators of drug abuse. Under no circumstances may a physician dispense controlled substances with the knowledge they will be used for a nonmedical purpose or that they will be resold by the patient. Some physicians who treat patients having a history of drug abuse require each patient to sign a contract agreeing to certain terms designed to prevent diversion and abuse, such as periodic urinalysis. While such measures are not mandated by the CSA or DEA regulations, they can be very useful.
