Not clinically reviewed — verify with your pharmacist

Some formulations contain gluten. Of 16 product labels we cross-checked, 2 list a gluten-derived ingredient outright. Generics from different manufacturers can differ — check which manufacturer's version your pharmacy dispensed before assuming any fill is safe.

Drug context

About prednisone

Prednisone is a corticosteroid used for inflammation, autoimmune disease, and asthma exacerbations, sold under brand names including Deltasone, Rayos.

Why this matters

Different manufacturers, different ingredients

Generics of prednisone use the same active ingredient, but they aren't required to use the same inactive ingredients. Your pharmacy may switch which manufacturer they dispense between fills, sometimes without telling you. The list below shows each manufacturer's product label as a separate entry, because that's the granularity that actually matters when you're celiac.

Background

What “gluten in a medication” actually means

Gluten enters drugs through their excipients — the inactive ingredients used to bind, coat, fill, or stabilize the dose. The main concern is wheat starch as a filler. Source-ambiguous starches (plain “starch”, pregelatinized starch, sodium starch glycolate, modified starch) get flagged for verification because their botanical origin isn't always disclosed on the label.

The 2024 Mangione et al. pediatric NDC analysis (689 NDCs across the top 100 pediatric medications) found 1.5% contained gluten outright; another 25.7% couldn't be confirmed either way. Liquid and oral-suspension formulations carry disproportionate risk because wheat starch is a common thickener. Full methodology →

Important. This page is informational. Drug labels can change without notice; a manufacturer attestation is point-in-time, not a warranty. If you have celiac disease and your pharmacy switches manufacturers, re-screen the new label before taking the dispensed product. For a definitive answer, call the manufacturer's medical-information line with the NDC code from your prescription bottle — or take our printable pharmacist card to the counter, which asks the three questions a pharmacist can actually answer.
