While little known outside of Canada, it is used there for the treatment of tough muscle pain, arthritic pains, rheumatic pains, bursitis, lumbago, etc.[2][3] Church and Dwight say on their website that nearly all the research, development and production of RUB A535 is carried out in Canada. Patients who are allergic to salicylates (ASA based drugs, such as aspirin), or who are taking anticoagulant medications should avoid the use of the product. It is also recommended to not use it more than 3–4 times a day.
Currently, RUB A535 has been released in a variety of products:
Originally, it was produced in a particular white cream, carrying a rather offensive medical odour.
Recently, the name was also given to a line of dual action back patches that change temperature (known as Hot-Cold patches).
An improved cream was also developed, claiming to be odorless, differing from their normal cream, which carries the same smell as most topical analgesics.
As of 2008, the "Ultra Heat" sport stick was released and shipped to many provinces, including Manitoba. It is sold as individual units containing 100g of spearmint-smelling cream in packaging resembling an orange-coloured, slightly taller than usual deodorant stick. Like some deodorant sticks, the cream is dispensed by first uncapping the unit, then turning a dial at the bottom of the unit, thus pushing the cream up and out through three slits at the top.
Historically, the then local distributor was involved in a notable case in the High Court of Australia, about State income tax, Denver Chemical Manufacturing Company v The Commissioner of Taxation (New South Wales)(1949) 79 CLR 296. It simply involved a difference of views about how to disclose income on a tax return, but is the leading authority in its area.
