MP calls for greater pharmacovigilance in Australia
Federal MP Julian Hill speaks with newsGP about increased pharmacovigilance in Australia following his daughter’s near-fatal experience with off-label prescribing.
Elanor Hill knew something was seriously wrong with her leg while on holiday in Sri Lanka earlier this year. Not long after the long-haul flight from Australia, she experienced pain and swelling in her calf that continued to worsen.
Her experience of working in a medical clinic meant Elanor was sensitive to the signs of deep vein thrombosis (DVT) and her father, Federal Labor MP Julian Hill, was able to get her to a hospital in time to address the clot in her leg.
Prior to the trip, 20-year-old Elanor had been prescribed Diane-35 for use as a contraceptive. While Diane-35 is regularly prescribed as a contraceptive in Australia, it is also used as an anti-acne medication. Diane-35 has previously been temporarily banned in France due to increased risk of blood clots.
In a speech to Federal Parliament last night, Hill said that his daughter had never been made aware she was being prescribed an off-label medication, nor of the fact it comes with a risk of blood clots. He is now calling for tighter restrictions on off-label prescribing, with patients given more information when prescribed a drug for a purpose other than that for which it is TGA-approved.
‘The point I have tried to make very rigorously, methodically and based on evidence and consultation with every part of the pharmacovigilance chain, is actually that there is a safer way to do things that reduces these risks and will definitely save lives and reduce the incidence of blood clots,’ he told newsGP.
Hill’s quest to improve pharmacovigilance in Australia has seen him engage with a number of healthcare bodies in Australia, including the RACGP, Pharmacy Guild of Australia, Pharmaceutical Society of Australia, National Prescribing Service, and the TGA.
‘There is room to improve Australia’s overall pharmacovigilance regime, or drug safety systems, because everyone has a little piece of that puzzle,’ he said. ‘Australia’s overall regime is a lot weaker than many countries in terms of making pharmacists aware and putting some extra thought or discipline on clinicians when they are doing off-label prescriptions.
‘There is no automatic notification of the pharmacist where that has been done, so the pharmacist can provide some extra education at the counter and say, “This is an off-label prescription, you have probably got some high risks, here’s a few of the things you should look out for”.’
An important factor in the case of Hill’s daughter Elanor was that she has a relatively common genetic mutation Factor V Leiden, an inherited blood-clotting disorder. However, there is no routine testing or screening for this disorder when prescribing Diane-35 in Australia.
‘Things like that Factor V Leiden test could easily be worked in to significantly reduce the risk [of blood clots]. Any doctor I have spoken to has said, “If I knew someone had that genetic disorder I would never prescribe this pill”,’ Hill said.
Hill understands that GPs must be supported if they are to perform a test for Factor V Leiden before prescribing Diane-35.
‘That [Factor V Leiden] test would need to be listed on the Medicare Benefits Schedule … which is it currently not,’ he said.
Hill does not pretend to have all of the answers in this situation. He knows that GPs and other healthcare professionals are extremely time-poor and always working with their patients’ best interest in mind. However, he sees cases like his daughter’s and believes Australia’s policy-makers have a role to play in helping the country’s doctors and pharmacists carry out the safest possible prescribing habits.
‘I strongly argue that it should be scheduled so there’s the requirement of a blood test, and a warning be put on the packet so that consumers are crystal clear that it’s not approved as a contraceptive in Australia,’ he said.
‘I also think that helps to support doctors in their role to explain to patients who may be pushing for this drug, that it is a more risky choice.’
