# Check Drug Dosage Information

Correct dosing is critical for medication safety and effectiveness. Too little and the drug does not work. Too much and you risk toxicity. Dosing varies by indication, patient age, weight, kidney function, and other factors. Quick access to official dosage information helps prevent errors.

The lookup_drug skill returns FDA-approved dosing information including recommended doses, maximum doses, administration routes, and special population considerations. This is the same information in official prescribing information but accessible programmatically.

Healthcare providers use this for quick reference during prescribing. Patients verify their prescription matches guidelines. Developers integrate it into medication management apps. Pharmacists use it for dose verification during dispensing.
