A number of western countries take a strategy that tries to make questionable-but-safe drugs legal-but-rarely-used. For one, they ban direct-to-consumer advertising; the USA and New Zealand are the only two developed countries where it's legal to advertise to consumers. And for another, state health-care systems will typically not pay for drugs that lack evidence of efficacy, and most people are used to getting their healthcare through the state health system. That leaves it technically legal for consumers to buy, out-of-pocket, a drug that can't be advertised to them. In practice a handful of people do so, but not too many. It looks like they do sell this in Europe. Although I'm not sure if that's because it's approved at all, or just because Europe considers it some kind of novelty product rather than a medical device; the FDA and EU categorization of drugs/devices/etc. is a bit different.
