Is my medication affected by genetics?
Type a brand or generic drug name. We'll show you every active ingredient and which ones are affected by pharmacogenetic variants.

Therapeutic classes with published pharmacogenetic guidelines.
How this works
- Many medications are combo products: Excedrin is acetaminophen + aspirin + caffeine; Vyvanse is a prodrug of dextroamphetamine; Fioricet contains butalbital, acetaminophen, and caffeine.
- When you search, we resolve the product to its active ingredients and check each against published pharmacogenetic guidelines (CPIC, FDA).
- If an ingredient is affected by a specific gene (CYP2D6, CYP2C19, SLCO1B1, etc.), we flag it with the strongest evidence level we have and link to the full drug page.
- "Not in database" means no strong published PGx guideline for that ingredient — not that genetics play no role. Evidence grows every year.
