Buying PrEP online
It is legal to buy generic PrEP online, sourced from outside the EU, so long as this is for personal use.
Personal use is defined as up to three months of daily PrEP.
Generic PrEP contains the same medicine as the brand product (Truvada). It is usually made by a different company to the one that had the orginal patent.
PrEP supplied by NHS clinics in the UK is also generic and different brands may be available at different places and times. Two widely used versions of generic PrEP are Tenvir-EM (from Cipla) and Ricovir-EM (from Mylan). Both versions are approved by the US FDA, which is essential.
Generics approved by the US FDA and or the European Medicines Agency (EMA) are safe to use. See FDA listing:
Sometimes buying PrEP online might take a while for the drugs to arrive. It is best to order at least a month in advance.
Make sure that you order a combined pill that contains both TDF and emtricitabine. For example, you need Tenvir-EM or Ricovir-EM rather than just Tenvir or Ricovir.
Several UK community websites have information about how and where to buy PrEP online.
There is always a caution when buying anything online. However, 56 Dean Street (a sexual health clinic in London) reported good drug levels using versions of generic PrEP listed on iwantPrEPnow. No HIV transmissions were reported from 400 people using generic PrEP for a year. 
Some clinics will support you and provide advice and monitoring if you buy PrEP online. However, the NHS is only responsible for meds that it supplies, for example, for the generic PrEP used in the IMPACT study.
The information on the community websites above will help make sure you get the right pills.
Which online suppliers can I use for PrEP?
i-Base does not endorse or guarantee any online supplier.
i-Base has no direct link to any online supplier, and no commercial link or conflict of interest.
This community page from IWPN if updated frequently if web suppliers change and inso included lots of practical advice about buying PrEP online.
The following websites sell generic versions of tenofovir/emtricitabine: Tenvir EM (manufactured by Cipla) and Tavin EM (manufactured by Emcure). This is one of the formulations approved by the US FDA and the WHO.
These suppliers appear to be established suppliers for a wide range of medicines including HIV and hepatitis C drugs.
[NOTE: we sometimes hear of supply issues with generic suppliers but these companies usually try very hard to resolve these. If problems occur, then first contact the company directly as often a replacement will be sent. i-Base have no direct links to these companies but please let us know if you have problems that might change our decision to list them.]
