People who need to treat Opioid Use Disorder may walk into any methadone clinic Irving Tx, where health providers are available to assist them. Methadone is combined with behavioral therapies and counseling to make a complete medication-assisted treatment package. Methadone is so effective that it has been included in the World Health Organization’s list of essential medications. Opioid addiction can cause psychological and physical harm, yet, people suffering from opioid use disorder cannot stop taking it because it relieves pain and gives euphoria. Methadone alleviates craving and withdrawal, and improves the patient’s ability to function socially and emotionally. The Substance Abuse and Mental Health Services Administration requires all methadone clinics in Texas to be accredited. Often, the treatment takes place in the clinic, but depending on the health provider’s observation of the patient’s compliance, some patients may be allowed to take methadone at home, between program visits.
