Doctor oft advise patient role not to buy generic drugs from the Internet . However ,   gay humans in London have been defying this advice for the last couple of year , and it is making an incredible departure . New HIV contagion rate in the Das Kapital have slumped by an impressive 40 percent , as gay men have change state to the Internet to bribe generic versions of thepre - exposure prophylaxis ( PrEP)drug Truvada .

New figures have show the striking deviation that the drug has made across four sexual wellness clinics in London , according toNew Scientist . investigator mistrust that the causal agent behind the monolithic drop-off in new infection is down to people turning to the Internet in rules of order to purchase   generic versions of the medicine , rather than pay the full price for the prescribed stuff .

“ We need to be very cautious at this stage , but I ca n’t see what else it can be , ” explains Will Nutland at the London School of Hygiene and Tropical Medicine , toNew Scientist . “ Something extraordinary has bechance in the last 12 months because of a bunch of DIY activist working off our kitchen tables . ”

HIV - electronegative men need to take the drug once a day to hack their risk of infection . Buying the official licensed stain under the name Truvada can cost £ 400 per calendar month , but price   cut variant in labs in places like India or Singapore can play this price down tobetween £ 40 and £ 50 per calendar month , making it much more affordable .

The legality of this is confutative , but with the drugs bought online and mailed through several countries before arriving at people ’s door , tracking the practice and stopping it can be difficult . apparently , there are safety fears and many doctors urge against it , but to dateno pills procured this way have been found to be fake .

Truvada stormed into   the mainstream view of HIV bar over the last few years when initial work found it can dramaticallycut the charge per unit of new infections , although there are a fewquestionsas to the hardiness   of some of the visitation .

It gained further visibility in the UK when   the National Health Service run to court to adjudicate and foreclose it from being required for them to provide the drug to gay men who are most at risk of contract HIV , a casewhich they finally lost .

How this result with further impact the rates are yet to be seen , but with the figure dropping by 40 pct in 2015 compared to the year before , the practice of medicine being usable on the NHS could have even more impressive issue .
