Some of the views expressed in the following notes on newly approved products should be regarded as preliminary, as there may have been limited published data at the time of publication, and little experience in Australia of their safety or efficacy. However, the Editorial Executive Committee believes that comments made in good faith at an early stage may still be of value. Before new drugs are prescribed, the Committee believes it is important that more detailed information is obtained from the manufacturer's approved product information, a drug information centre or some other appropriate source.

Injecting neonates with vitamin K (phytomenadione) has been an effective method of preventing haemorrhagic disease of the newborn. In the early 1990s a possible link between these injections and childhood cancer was reported.1 Although other studies have not confirmed this link, the National Health and Medical Research Council advised that vitamin K could be given orally as an alternative to injection. The intramuscular formulation was not ideal for oral use and has now been replaced by a formulation which is approved for oral and intramuscular use.
Health professionals need to be aware that the new formulation has different regimens. Not only are repeat oral doses required for babies given vitamin K by mouth, but also for babies who are breast-fed following an injection. The regimens for prophylaxis are:
Healthy breast-fed neonates
Healthy formula-fed neonates
Neonates at risk of haemorrhagic disease
To reduce the risk of late-onset bleeding, it is important to remind parents to ensure that the recommended repeat doses are given.
