The 70-year-old steroid still shows up as FDA-labeled treatment across asthma, arthritis, lupus, eczema, and 9 others. Modern biologics target fewer conditions but far more precisely.

Rheumatoid arthritis now has 56 FDA-labeled drugs

Before 2000, RA treatment meant methotrexate and steroids. The arrival of TNF inhibitors (Adalimumab, Etanercept) and JAK inhibitors turned a progressive disease into a managed one.

ADHD is covered by 23 FDA-labeled medications

Our older matcher showed zero because the FDA files it under "Attention Deficit Disorder with Hyperactivity." The catalog now links both names so a patient searching "ADHD" finds every approved treatment.

91 of our 128 tracked procedures share a name with a condition they treat

Knee replacement treats knee osteoarthritis. Mastectomy treats breast cancer. When the fix is surgical rather than pharmacological, the procedure page is the more useful next click.

Internal medicine alone covers 198 of 1,185 conditions

Most conditions start with a primary-care visit. Family medicine covers another 149, pediatrics 156. Narrower specialties see smaller slices by design — that’s what specialization means.

Frequently Asked Questions

How to use this page, and what the numbers mean.

How do I find my condition if I only know the common name?

Use the search box at the top of the page. It checks condition names, aliases (like "hypertension" → "High Blood Pressure"), and our body-system labels. Most conditions have at least 3 aliases; many have 10 or more.

Why do some conditions show no drugs?

Drug counts come from matching condition names against FDA-labeled indications. Only 346 of 1,185 conditions returned a match. A zero doesn’t mean no treatment exists — it often means the FDA label uses a different clinical name than our catalog. Surgical and behavioral conditions legitimately have no pharmacological treatment.

How are conditions organized?

Each condition sits in one of 22 body-system categories. Musculoskeletal is largest among named systems (105 conditions); Heart & Cardiovascular, Cancer & Oncology, and Brain & Neurological each hold roughly 45. The "Other" bucket holds 453 conditions that don’t fit a single system, mostly infections, genetic disorders, and cross-system syndromes.

How do I find a specialist for my condition?

Open any condition page and scroll to the specialties section. Each condition lists the specialties trained to diagnose and treat it. Click a specialty to see doctors nationally or filtered to your state.

What happened to procedure, screening, and "how-to" entries?

We quarantined 165 entries that weren’t conditions — surgical procedures (Appendectomy, Mastectomy), screenings (Newborn Screening), therapies (CPAP, Allergy Shots), diagnostic tests (MRI, Biopsy), and how-to guides. They still have their own detail pages but don’t appear in browse or search here.

Methodology & Sources

How this catalog was built and what it includes.

SourcesCondition catalog: MedlinePlus (NLM), MeSH codes (NLM), CDC, clinical specialty societies. Drug-condition matches: FDA drug labels via openFDA and structured product labels.

Cleaning165 entries were quarantined from browse and search: procedures (Appendectomy, Mastectomy), screenings, therapies, diagnostic tests, and how-to guides. Those pages remain reachable at /conditions/[slug] but don’t appear here.

Drug matching346 of 1,185 conditions (29%) return at least one FDA-labeled drug. Zero-drug conditions include surgical-only diagnoses, symptom names, and cases where the FDA uses a clinical synonym our matcher didn’t catch. We show what we can verify; absence of a match is not a judgment on the condition.

UpdatesCatalog updates as new MeSH codes are released; drug-condition matches regenerate when the FDA drug file refreshes.
