Is there a generic for DALIRESP?: Roflumilast explained
Yes, the generic version of the brand-name medication Daliresp has been commercially available since 2022. The generic name for Daliresp is roflumilast. This is significant for patients with severe Chronic Obstructive Pulmonary Disease (COPD), as generic medications are often substantially cheaper than their brand-name counterparts. This affordability can lead to better treatment adherence for individuals managing chronic conditions.
FDA approval and availability
The U.S. Food and Drug Administration (FDA) first approved generic versions of roflumilast, the active ingredient in Daliresp, in 2022. Several pharmaceutical companies have received approval to manufacture and market the drug. For instance, Zydus Pharmaceuticals USA Inc. and Aurobindo Pharma have both received FDA approval for their generic roflumilast tablets. This increased competition among manufacturers contributes to lower market prices.
The regulatory process ensures that these generic drugs are bioequivalent to the original brand-name drug. According to the FDA, generic medications must have the same active ingredient, strength, quality, and safety profile as their brand-name version. This means patients taking generic roflumilast can expect the same therapeutic effect as they would from Daliresp.
How does roflumilast work?
Roflumilast belongs to a class of drugs known as phosphodiesterase-4 (PDE-4) inhibitors. Its mechanism of action involves blocking the PDE-4 enzyme, which plays a critical role in inflammation within the body. In patients with severe COPD, this drug works to reduce the swelling and inflammation in the airways that lead to a worsening of symptoms, also known as exacerbations.
Roflumilast is intended for maintenance treatment and is not a fast-acting rescue medication. It is typically prescribed to patients with severe COPD and a history of frequent flare-ups, particularly those with chronic bronchitis. It is important for patients to continue using any other prescribed COPD medications, including bronchodilators, as directed by their healthcare provider.

Potential benefits of choosing generic roflumilast
Opting for a generic medication offers several advantages for patients with severe COPD:
- Cost Savings: Generic drugs are typically priced much lower than brand-name drugs, which can dramatically reduce out-of-pocket costs for individuals. This is particularly beneficial for those on fixed incomes or without comprehensive prescription drug coverage.
- Increased Access: Lower prices can increase the accessibility of necessary treatment for more patients, improving overall public health outcomes.
- Assured Quality: The FDA's rigorous approval process for generic medications ensures they meet the same high standards for quality, strength, and purity as brand-name drugs.
- Greater Competition: The introduction of multiple generic manufacturers into the market fosters competition, which helps drive down prices and maintain affordability over time.
Important considerations and patient information
When switching from Daliresp to generic roflumilast, it is crucial to consult a healthcare provider. While the active ingredient is identical, there may be slight differences in inactive ingredients or fillers. These differences rarely cause issues but should be discussed with a doctor, especially for patients with sensitivities or allergies.
Patients should be aware of the medication's side effects, which can include diarrhea, weight loss, nausea, and headache. The medication can also cause mood or behavioral changes, so patients with a history of depression or suicidal thoughts should be monitored closely. Roflumilast should not be used to treat acute breathing problems and is intended for long-term, daily use as a maintenance therapy. For more information, refer to the prescribing information, which can be found on sites like the DALIRESP® website.

Yes, there is a generic for DALIRESP, and its availability as roflumilast offers a significant advantage for patients managing severe COPD. By providing an equally effective, but much more affordable, treatment option, generic roflumilast helps alleviate financial burdens and promotes better access to care. As with any medication change, patients should consult their doctor or pharmacist to ensure a smooth transition and understand all potential considerations.
