Bek, you might also like to call Dr Rodney Whyte at the Monash Medical Centre drug information line. He is the guru on drugs and bfing - his number during office hours is (03) 9594 2361. There are actually very few drugs which can't be taken while bfing but the database used by doctors and pharmacists is overly conservative. There is a very good chance that you could take the treatment while bfing and Dr Whyte will be able to tell you if this is indeed the case for you.
