• Summary Background Topical photodynamic therapy (PDT) is widely used to treat superficial nonmelanoma skin cancer and dysplasia, and is generally well tolerated. However, as with all treatments, adverse effects may occur and awareness may facilitate approaches to prevention and management. Objectives To review the available evidence relating to the adverse effects of topical PDT, to help inform recommendations in updated clinical guidelines produced by the British Association of Dermatologists and British Photodermatology Group, and the efficacy of preventative and therapeutic approaches. Methods This review summarizes the published evidence related to the adverse effects of topical PDT and attempts to interpret this evidence in the context of patient risk and management. Results Pain and discomfort during PDT are acute adverse effects, which can be minimized through the use of modified and low‐irradiance PDT regimens and do not therefore usually limit successful treatment delivery. Other adverse effects include the risk of contact allergy to photosensitizer prodrugs, although this is rare but should be kept in mind, particularly for patients who have received multiple PDT treatments to larger areas. There are no other significant documented longer‐term risks and, to date, no evidence of cumulative toxicity or photocarcinogenic risk. Conclusions Topical PDT is usually well tolerated, reinforcing the utility of this important therapeutic option in dermatology practice. The main acute adverse effect of pain can typically be minimized through preventative approaches of modified PDT regimens. Other adverse effects are uncommon and generally do not limit treatment delivery. What's already known about this topic? Photodynamic therapy (PDT) is widely used in dermatology. Pain is the most well documented adverse effect. Methods of effective pain relief are limited. What does this study add? This review scrutinizes the literature relating to adverse effects of PDT and management approaches. PDT‐induced pain can usually be effectively prevented and managed through adjustments to PDT regimens, such as using lower irradiance light delivery. Phototoxic reactions are to be expected. Other adverse effects are typically uncommon and not limiting. Linked Editorial: Wulf. Br J Dermatol 2019; 180:695–696. Plain language summary available online
