Frequently asked questions

Where does this drug information come from?
Every drug page is built from the official prescribing information or Drug Facts label that the manufacturer submits to the FDA, published through openFDA and the FDA NDC Directory.
What is a boxed warning?
A boxed warning (black box warning) is the FDA's strongest warning. It appears at the top of a prescription label when a drug carries a risk of serious or life-threatening side effects.
What is the difference between Rx and OTC?
Prescription (Rx) drugs need a prescription from a licensed prescriber. Over-the-counter (OTC) drugs can be bought without one and carry a standard Drug Facts label.
Is a generic drug the same as the brand?
FDA-approved generics have the same active ingredient, strength, dosage form and route as the brand-name drug. Each drug page lists other products with the same active ingredients.
