Rule out RU486 restrictions, Abbott told Opposition Leader Tony Abbott has "form" in trying to block access to controversial abortion drug RU486 and needs to rule out restricting it if he wins government, the Australian Greens have demanded. The Pharmaceutical Benefits Advisory Committee is expected on Friday to recommend RU486 be made available on the Pharmaceutical Benefits Scheme (PBS), which could see its price drop by hundreds of dollars. Mr Abbott said he would accept the advice of health experts on drugs such as RU486 should he be elected prime minister, despite having blocked access to the abortion pill when he was health minister in the Howard Government. His refusal to allow the RU486 to be made available in Australia eventually led to a 2006 conscience vote in the parliament which stripped the health minister of regulatory control of the drug. "When I was in government, we invariably accepted the advice of our technical advisers," he told reporters in Adelaide on Friday. That was the way I operated as (health) minister. Greens health spokesman Richard Di Natale welcomed Mr Abbott's comments, but said the opposition leader needed to rule out taking steps to restrict the drug if the coalition won government. "Tony Abbott has got form in this area - he was a huge stumbling block to reform in the past," Senator Di Natale told reporters in Canberra. I just hope this isn't a comment in the lead-up to an election that he tries to undo if he forms the next government. The question was whether Mr Abbott would continue to respect the advice of experts after the election, Senator Di Natale said. He called on Health Minister Tanya Plibersek to accept the advice of the advisory committee and list the drug as soon as possible, saying "We can't afford for it to be a political football going into this election." "I'm hopeful that the government will recognise just how critical it is ... to get the drug listed on the PBS ... and making sure that it's going to be harder for an Abbott government to undo it in the future," he said. The Australian Christian Lobby opposes listing RU486 on the PBS, saying for ethical and health reasons it would be wrong for "this just to be waved through." Senator Di Natale dismissed the ACL's objection, saying "Last time I looked the appropriate regulator here was the Therapeutic Goods Administration." "What they are effectively saying is that they know more than the health experts that we put in place to make sure drugs are safe," he said.
