n8n Pharma Label Change Analyzer with Claude + Slack Compliance

Automatically detect drug label changes, analyze impact with Claude, and route compliance reviews in Slack

The n8n Pharma Label Change Analyzer with Claude + Slack Compliance workflow continuously monitors a configured regulatory drug label source for updates. When the label changes, it uses Anthropic Claude to assess the impact, then routes the review through Slack with the right level of sign-off—before updating your product master data and logging a compliance record.

What this workflow does

• Runs on a schedule (or manually): Loads the configured product, label source URL, and notification settings.
• Fetches and compares label text via HTTP: Pulls the current label from your regulatory source and compares it to the last stored baseline.
• Avoids unnecessary AI calls: If the label is unchanged, the workflow ends without calling Claude.
• Analyzes changes with Claude: If a change is detected, it gathers related product/process/batch details, then sends the previous vs. new label text plus context to Anthropic Claude for impact analysis.
• Parses Claude JSON output: Extracts a change summary, changed sections, severity (Critical/Major/Minor), and required actions for Regulatory and Quality.
• Slack-based review routing: Critical changes go to a blocking sign-off step; Major/Minor changes trigger a Slack review alert while continuing.
• Updates systems with auditability: After approval (or for Major/Minor), it updates the product master record, logs the compliance/audit record, posts to Regulatory and Quality Slack channels, emails a summary, and saves the new label as the next baseline.

Use cases

• Pharma teams tracking label revisions from regulatory sources without manual checking.
• Automation engineers needing an n8n workflow for recurring compliance review and documentation.
• SaaS operators supporting multiple products/processes/batches with consistent approval routing.
