Human immunodeficiency virus (HIV) continues to present a public health problem, and pre-exposure prophylaxis (PrEP) offers a promising preventative intervention; however, its uptake remains low, so investigating determinants of use is essential. This article applies queer critical discourse analysis to a corpus of 121 TikToks sampled via the TikTok algorithm, coded and refined into three overarching content categories: 'what makes a PrEP user?', 'what is PrEP as a drug?', and 'sexual health and HIV'. Examples from within these categories reveal four underlying discursive themes: (1) stigmatisation of HIV as a 'gay disease' with a poor prognosis; (2) stigmatisation of gay men as unsafe, high-risk and untrustworthy; (3) stigmatisation of PrEP as increasing 'unsafe' sexual practices; (4) poor healthcare and education gay men and other beneficiaries of PrEP. These themes are influenced by a broad spectrum of homophobic and heteronormative discourses available with specific examples reflecting parts of this spectrum from predominantly perpetuating to occasionally challenging. The findings report complementary evidence obtained from other media platforms yet offer a unique take while suggesting useful avenues for future public health messaging relating to PrEP which may be used to inform the next steps against HIV.
