The sections below are summarized in plain English from beclomethasone's FDA-approved prescribing information. They describe what the official label says, and are not personal medical advice.

How It Works

Qvar Redihaler contains beclomethasone, a type of corticosteroid. Corticosteroids reduce inflammation in the airways. This makes it easier to breathe and helps prevent asthma symptoms.

Known Drug Interactions

Alternative corticosteroids including beclomethasone, prednisone and prednisolone (for which PK and/or PD are less affected by strong CYP3A inhibitors relative to other steroids) should be considered, particularly for long term use.

Mechanism: Darunavir can slow down how your body gets rid of beclomethasone, though this effect is smaller than with other similar steroids.

Alternative corticosteroids including beclomethasone, prednisone, and prednisolone should be considered.

Mechanism: Ritonavir can cause problems with many steroids, but beclomethasone is suggested as a safer alternative that is less likely to be affected.

What the FDA Data Shows for beclomethasone

The FDA label for beclomethasone (sold under brand names such as Qvar) classifies it as a prescription-only medication in the Inhaled Corticosteroid class. Qvar Redihaler is used to treat asthma and prevent asthma attacks in adults and children 4 years and older.

Post-market surveillance from the FDA Adverse Event Reporting System (FAERS) captures real-world experience. Voluntary reports accumulate over the lifetime of a drug and reflect wide-ranging clinical use. The database also lists 2 documented drug interactions derived from FDA labeling, with the top-flagged interaction rated minor severity. Acquisition-cost data is surveyed weekly by CMS and updated as manufacturers report changes.

Report counts do not establish causation, a FAERS entry documents a temporal association, not proof that the drug produced the outcome. Widely prescribed medications naturally accumulate more reports than niche therapies, so raw totals must be interpreted alongside total exposure. Shortage status, recall history, and patent information are separate source-record fields. This page is a public FDA/CMS registry and does not provide medical, treatment, substitution, or medication-change directions.
