Drug interactions

The University of Liverpool Drug Interactions Group has over 25 years of experience in developing and maintaining world-renowned prescribing support tools. Our resources are crucial for the clinical management of drug-drug interactions (DDIs) in areas such as HIV, Hepatology, and COVID-19.

Our tools and resources 

Our suite of websites and mobile applications offers a range of easy-to-use checkers that provide: 

• Clinically useful recommendations: Using a ‘traffic lights’ system for clarity
• Evidence-based insights: Quality of evidence synthesis analogous to GRADE evaluations
• Comprehensive coverage: A database of over 100,000 drug interaction-pairs. 

These tools are freely available to healthcare professionals, researchers, and patients around the world. Each year, we handle over 16 million searches across 220 countries and territories. Our resources are integrated into a multitude of treatment guidelines across six continents and are referenced in WHO guidance and toolkits.
