Research Drug Side Effects
Query FDA adverse event reports to understand the real-world side effect profile of any medication.
Look Up Drug Interactions
Check for potential interactions between medications before prescribing or taking them together.
Quick answer: Use the Drug Info tool through ToolRouter to look up drug interactions directly from Claude, ChatGPT, Microsoft Copilot, and OpenClaw — connect once, then drive it with plain-language prompts. No code required.
ToolTaking multiple medications creates risk. Some drugs amplify each other, some cancel each other out, and some combinations are dangerous. Patients, caregivers, and healthcare professionals need fast access to interaction data when evaluating a medication regimen.
The lookup_drug skill queries FDA databases for detailed drug information including known interactions, contraindications, and warnings. Instead of searching through package inserts or medical databases manually, you get structured interaction data in seconds.
This is useful for pharmacists reviewing prescriptions, patients managing multiple conditions, caregivers coordinating between specialists, and developers building medication management apps. Programmatic interaction data integrates directly into clinical workflows and patient-facing tools.
