Spring 2008 saw the introduction of Alli Orlistat, the strong prescription strength slimming pill, but available to buy over the counter at selected high street and online stores.

Boots the Chemist, Superdrug and most of the major supermarket chains were authorised to sell Alli off the shelf – but certain restrictions did apply. It was not quite as simple as popping a packet in your shopping basket and paying at the checkout.

To qualify to purchase Alli customer had to be in a real need of a weight loss product – a BMI (Body Mass Index) of over 28 was the most obvious requirement.

Customers wishing to buy from the high street had to and still have to complete a questionnaire detailing their lifestyle and certain question that could be perceived as rather embarrassing.

High street prices are still reasonably good but the the prices offered via some authorised online pharmacies are more competitive – plus of course the questionnaire can be completed in relative privacy.
