# Find Generic Drug Alternatives

Brand-name drugs can cost ten times more than their generic equivalents, yet many patients do not know a generic option exists. When a patent expires, other manufacturers can produce the same active ingredient at a fraction of the cost. The FDA database tracks these relationships.

The lookup_drug skill returns detailed drug information including active ingredients, making it straightforward to identify generic alternatives. Search for a brand name, find the active ingredient, then search for that ingredient to discover all available generic versions.

This is valuable for patients reducing medication costs, employers evaluating formulary options, insurance companies assessing coverage policies, and anyone building tools that help people find affordable medications.
