Users of Claramax (the anti-histamine product), in Sydney at least, might be shocked to find the product is in very short supply. I had to visit seven chemists before finding one with any in stock at all. And at the seventh, I bought their last two packets.
The chemists I asked are reporting that there has been a manufacturing problem and they have been unable to get new stocks in for some time ("for months" according to one Mosman pharmacist).
As to when new stocks are due, another chemist reported she had no information, and that even if a date was provided (she didn't indicate by who) that the information was unreliable.
