drug-interactions-checker

A lightweight standalone npm library for checking medical drug interactions. Uses a comprehensive JSON dataset of known interactions.

Installation

npm install drug-interactions-checker

Usage

const { checkInteraction, getInteractions, getAllInteractions } = require('drug-interactions-checker');

// 1. Check a specific interaction
const interaction = checkInteraction('Acetaminophen', 'Warfarin');
if (interaction) {
  console.log(interaction.description);
  // Example output: "Combining Acetaminophen with Warfarin can increase the risk of bleeding by elevating INR levels."
}

// 2. Get all interactions for a specific drug
const aspirinInteractions = getInteractions('Aspirin');
console.log(`Found ${aspirinInteractions.length} known interactions for Aspirin.`);
// Returns an array of interaction objects

// 3. Get the entire dataset
const allData = getAllInteractions();

Data Source

The data is included as a JSON file bundled within the module (data.json) and queries are made directly against this imported module data. The dataset contains fields:

• drug: First referenced drug
• interacting_drug: Second referenced drug
• description: A short summary of the interaction
• extended_description: Additional clinical details and extended information.
