Many hospitals in Australia offer a Medicines Information service, usually for the purposes of supporting hospital staff and patients. Some MI services offer assistance to external health professionals and consumers.
Pharmaceutical companies usually provide a service for enquiries about their products, as this helps them to fulfill their legal pharmacovigilance and reporting obligations, however the scope of enquiries that they are able to accept may be limited.
A contact list of MI services in Australia is available on the SHPA website.
