Dear Pharmacist
You may find in the coming months that generic pregabalin is available to order. I would like to highlight to you that although the patent for pregabalin expired in July 2014, this patent expiry related to the use of pregabalin in epilepsy and generalised anxiety disorder; Pfizer will retain a patent for the use of pregabalin in the treatment of peripheral and central neuropathic pain in adults until July 2017.
This means that until July 2017, generic manufacturers of pregabalin will only be able to obtain a licence for pregabalin for use in epilepsy and/or generalised anxiety disorder and Lyrica, Pfizer’s branded product, will remain the only product licensed for use in pain as well as epilepsy and generalised anxiety disorder.
Pfizer has indicated that it will contest any challenges to the patent for pain.
To avoid any possible patent infringement by pharmacists, steps will need to be taken to ensure that where generic pregablin is requested on a prescription the correctly licensed product is supplied. This may mean contacting the prescriber and establishing the indication and requesting that the prescription is amended and ordered by brand as Lyrica if necessary.
Although generic pregabalin is unlikely to differ clinically from the branded Lyrica, supplying the generic version of pregabalin for neuropathic pain may have the following implications for pharmacists:
When supplying pregabalin for the treatment of epilepsy, pharmacists should also consider MHRA guidance issued in 2013 regarding the generic prescribing of antiepileptics. The guidance states that pregabalin does not generally need to be prescribed by brand for the treatment of epilepsy unless there are specific concerns such as patient anxiety and a risk of confusion or dosing errors.

Although generic pregabalin is unlikely to differ clinically from the branded Lyrica, supplying the generic version of pregabalin for neuropathic pain may have the following implications for pharmacists:
- Generic pregabalin preparations will not include information relating to neuropathic pain in the patient information leaflet and pharmacists will be supplying a product off-licence
- Supplying generic pregabalin for neuropathic pain would not be in line with Medicines and Healthcare products Regulatory Agency’s risk hierarchy guidance for the supply of unlicensed medicinal products, which states that a UK-licensed product should always be supplied for the correct licensed indication
- Using generic pregabalin for neuropathic pain may be deemed by Pfizer to be a patent infringement by all parties concerned, including the prescriber and the supplying pharmacist
