Your donation will help to keep Hepatitis drug interactions and its associated app HEP iChart up-to-date, comprehensive and freely available worldwide.

We receive no government funding and therefore must continually fundraise in order to cover the costs of maintaining this site to the high standards our users rightly expect.

If you value this resource, please consider making a donation of any amount to support the site’s future. As a guide:

  • £11 covers the monthly cost per user of running this site
  • £50 covers our web hosting costs for one week
  • £500 means we can add several new co-medications to the interaction checker
  • £5,000 supports the web development of new features.

If you would like to fundraise on our behalf, or have another idea about how you could support us, please contact
