ObjectiveLower urinary tract symptoms (LUTS) are becoming more prevalent in the ageing population of males living with HIV. Drugs to treat LUTS are known for both their potential role as victims in drug–drug interactions (DDIs) and their side effects. We aimed to evaluate the current use of drugs to treat LUTS and to assess potential DDIs in our cohort of adult males living with HIV.DesignThis was a retrospective review of pharmacy records.MethodsWe recorded the combination antiretroviral therapy (cART) regimen and any use of drugs to treat LUTS (anatomical therapeutic chemical codes G04CA/CB/CX and G04BD). Potential DDIs were assessed using the interaction checker developed by the University of Liverpool (https://www.hiv-druginteractions.org/checker).ResultsA total of 411 adult males living with HIV were included in this analysis. The median (interquartile range [IQR]) age was 53 (41–62) years. Nineteen (4.6%) patients used one or more drugs to treat LUTS. As expected, older patients were more likely to be receiving treatment for LUTS: Q1 (20–40 years) = 0%; Q2 (41–52 years) = 2%; Q3 (53–61 years) = 7%; Q4 (62–79 years) = 10%. Seven potential DDIs between cART and LUTS treatment were noted in six of the 19 (32%) patients. Following medication reviews of these six patients, the following interventions were proposed: evaluate safe use of alpha‐blocker (n = 4), change in cART (n = 2), and dose reduction of the anticholinergic agent (n = 1).ConclusionTreatment for LUTS coincided with cART in 7%–10% of patients aged above the median age of 53 years in our cohort. Improvements in DDI management appeared to be possible in this growing cohort of males living with HIV and with LUTS.
