Naloxone Hcl15$90.17 Less than typical

About Naloxone Hcl: This medication is used for the emergency treatment of known or suspected opioid overdose. Show more ▾

Serious opioid overdose symptoms may include unusual sleepiness, unusual difficulty waking up, or breathing problems (ranging from slow/shallow breathing to no breathing). Other symptoms of overdose may include very small pinpoint pupils, slow heartbeat, or low blood pressure. If someone has serious overdose symptoms but you are not sure if the symptoms are due to overdose, give this medication right away anyway, since lasting slow/shallow breathing may cause permanent damage to the brain or death. This medication belongs to a class of drugs known as opioid antagonists. It works by blocking the effects of the opioid in the brain. This medication may not work as well to block the effects of certain types of opioids (mixed agonist/antagonists such as buprenorphine, pentazocine). With these types of opioids, blocking may be incomplete or you may need a higher dose of naloxone. The effects of naloxone will not last as long as the effects of the opioid. Since treatment with this medication is not long lasting, be sure to get medical help right away after giving the first dose of naloxone. Treatment of opioid overdose should also include breathing treatment (such as oxygen given through tubes in the nose, mechanical ventilation, artificial respiration). A specific opiate antagonist that has no agonist activity. It is a competitive antagonist at mu, delta, and kappa opioid receptors.

In 2023, this provider wrote 15 Medicare prescriptions for Naloxone Hcl, about a third of the volume of the typical Colorado prescriber of this medication (39). Medicare paid an average of $90.17 per fill, versus $87.90 statewide.

About this data. The prescription history for JONATHAN T YAMAGUCHI 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 Orthopaedic Surgery prescribing approach at this Denver, CO 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 CO prescribers of the same medication. Always confirm current medications and costs directly with the provider and your plan.
