The British National Formulary (BNF) (Joint Formulary Committee, 2014) or summary of product characteristics provides more detailed information on the drug, interactions and how to use it in special circumstances. For complex regimes or pregnancy please refer to local and national guidelines. Pregnancy treatment regimens have not been included here as it is essential to get additional support to ensure the pregnancy is not ectopic. As gonorrhoea has the ability to develop resistance to antibiotics, consideration should be given to the risk of this infection. Gonorrhoea has already developed a quinolone resistance of greater than 5% (cut off before amending first-line treatment choices); therefore, patients at high risk of this infection should not be prescribed oflaxacin (regimen 2) (BASHH, 2011; Gonococcal Resistance to Antimicrobials Surveillance Programme (GRASP, 2013). Ceftriaxone injection is currently the firstline treatment for gonorrhoea (GRASP, 2013), so regime 1 should be used in patients at high risk of this STI (BASHH, 2011). Microscopy in sexual health departments is a useful tool to help identify gonorrhoea at the presenting visit which may help support treatment options until culturing results are back (Bignell and FitzGerald, 2011). To aid adherence to treatment it is important that the patient is involved in ‘shared decision making’.This will allow the patient to convey their concerns
