About Trelegy Ellipta: This product is used to control and prevent symptoms (such as wheezing and shortness of breath) caused by asthma and ongoing lung disease (chronic obstructive pulmonary disease-COPD, which includes chronic bronchitis and emphysema). Show more ▾

Controlling symptoms of breathing problems helps you stay active. This inhaler contains 3 medications: fluticasone, umeclidinium, and vilanterol. Fluticasone belongs to a class of drugs known as corticosteroids. It works by reducing swelling of the airways in the lungs to make breathing easier. Umeclidinium belongs to a class of drugs known as anticholinergics and vilanterol is a LABA medication. Both drugs work by relaxing the muscles around the airways so that they open up and you can breathe more easily. Both drugs are also known as bronchodilators. When used alone, long-acting beta agonists (such as vilanterol) may rarely increase the risk of serious (sometimes fatal) asthma-related breathing problems. However, combination products containing both an inhaled corticosteroid and long-acting beta agonist, such as this product, do not increase the risk of serious asthma-related breathing problems. For asthma treatment, this product should be used when breathing problems are not well controlled with two asthma-control medications (such as inhaled corticosteroid and long-acting beta agonist) or if your symptoms need combination treatment. This medication must be used regularly to be effective. It does not work right away and should not be used to relieve sudden shortness of breath. If sudden breathing problems occur, use your quick-relief inhaler as prescribed.

About this data. The prescription history for RALPH MAROUN MD 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 Pulmonary Disease prescribing approach at this Reston, VA 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 VA prescribers of the same medication. Always confirm current medications and costs directly with the provider and your plan.
