About Buprenorphine-Naloxone: This medication contains 2 medicines: buprenorphine and naloxone. Show more ▾

It is used to treat opioid dependence/addiction. Buprenorphine belongs to a class of drugs called mixed opioid agonist-antagonists. Buprenorphine helps prevent withdrawal symptoms caused by stopping other opioids. Naloxone is an opioid antagonist that blocks the effect of opioids and can cause severe opioid withdrawal when injected. It has little effect when taken by mouth or dissolved under the tongue. It is combined with buprenorphine to prevent abuse and misuse (injection) of this medication. This combination medication is used as part of a complete treatment program for drug abuse (such as compliance monitoring, counseling, behavioral contract, lifestyle changes). Ask your doctor or pharmacist if you should have other forms of naloxone available to treat opioid overdose. Teach your family or household members about the signs of an opioid overdose and how to treat it.

In 2023, this provider wrote 161 Medicare prescriptions for Buprenorphine-Naloxone, about 3.1 times the volume of the typical Arizona prescriber of this medication (52). Medicare paid an average of $136.79 per fill, versus $174.16 statewide.

About Buprenorphine Hcl: Buprenorphine is used to help relieve severe ongoing pain. Show more ▾

Buprenorphine belongs to a class of drugs known as opioid analgesics. It works in the brain to change how your body feels and responds to pain. Do not use this medication to relieve pain that is mild or that will go away in a few days. This medication is not for occasional (as needed) use. A derivative of the opioid alkaloid THEBAINE that is a more potent and longer lasting analgesic than MORPHINE. It appears to act as a partial agonist at mu and kappa opioid receptors and as an antagonist at delta receptors. The lack of delta-agonist activity has been suggested to account for the observation that buprenorphine tolerance may not develop with chronic use.

In 2023, this provider wrote 57 Medicare prescriptions for Buprenorphine Hcl, about 1.6 times the volume of the typical Arizona prescriber of this medication (35). Medicare paid an average of $55.75 per fill, versus $79.97 statewide.

About this data. The prescription history for MR. THOMAS CHARLES STEVENS JR. NP is compiled from the Centers for Medicare & Medicaid Services (CMS) Medicare Part D Prescriber Public Use File for calendar year 2023, the most recent federal release. Figures cover prescriptions filled for Medicare Part D beneficiaries only; prescriptions under private insurance, Medicaid, or self-pay plans are not included. Because prescribing decisions are generally consistent across coverage types, this record offers a useful view of the overall Psychiatric/Mental Health prescribing approach at this Phoenix, AZ practice.

Reading the costs. Drug costs are gross amounts paid to pharmacies under Part D, including both plan and beneficiary payments. They are not the price a patient pays at the pharmacy counter. Medications with fewer than 11 claims are excluded from the federal source data, and state comparisons use the average volume among AZ prescribers of the same medication. Always confirm current medications and costs directly with the provider and your plan.
