Amid new efforts from the White House to rein in skyrocketing drug prices, like calling for greater price transparency and pressuring manufacturers to limit price hikes, four drugs saw price increases of more than 9% this August.

Dollar bills and prescription bottles

The GoodRx Index also showed the following trends in the month of August:

  • Given an unusually tough fire season, prescription fills for inhalers are on the rise, by as much as 15% since July in some cases.

  • Actimmune, used to treat osteoporosis and chronic granulomatous disease, continues to be the most expensive drug in the US.  

This data reflects overall US prescriptions (not fills using GoodRx) and comes from several sources, including pharmacies and insurers, providing a representative sample of nationwide prescription drug volume.

Prices for 4 drugs increased by more than 9%

Four drugs saw large price increases over 9% this August:

  • Ery is an antibiotic used to treat bacterial infections. While most people are filling for the generic, erythromycin, the price for one jar of Ery increased by 15% from $67.14 to $77.21 in August.

  • Plexion is a sulfa antibiotic that is used on the skin to treat acne and rosacea. All forms and dosages of Plexion increased by 9.9% in August.

  • Doralis a benzodiazepine used to treat insomnia. The list price for one 15 mg tablet increased by 9.4% in August from $21.48 to $23.50.

  • Veltassa is a potassium binder, and it’s used to treat hyperkalemia (high potassium levels in the blood). The price for one packet of Veltassa (8.4 g, 16.8 g or 25.2 g) increased by 9.4% from $25.00 to $27.36 in August.

These prices are based on list prices—the price set by the drug manufacturer.

Claims for inhalers are on the rise

According to the GoodRx Index, fills for Ventolin, ProAir and Qvar increased by 19%, 15% and 11% respectively from July to August. This does not come as a surprise though, considering the especially bad fire season that has affected a majority of the western United States.

Since the beginning of summer, more than 50 large fires have devastated parts of the western United States, spreading smoke and increasing asthma rates. Fire season started early this year, so it’s likely that fills for inhalers will increase if new fires arise.
