In 2015 Dr Kirkland investigated websites offering treatment for gonorrhoea which experts said put patients at risk by not following best treatment guidelines. The treatment regimen means patients need a powerful antibiotic, which can only be injected, alongside an oral tablet. The BBC found seven UK-based websites offering only oral antibiotics. Such treatment can mean for some patients the infection may not be treated and can lead to antibiotics becoming less effective. The websites, identified in 2015 included Superdrug. The company said they were providing a vital service.

In response to the findings the British Association of Sexual Health and HIV wrote to the Chief Medical Officer. Later that year the Chief Pharmaceutical Officer and the Chief Medical Officer wrote to all GPs and pharmacists, including those online reminding them of their responsibilities.

Superdrug no longer provides online gonorrhoea prescribing services.
