Introduction Topical medications are one of the most commonly used therapeutic agents in treating a wide spectrum of dermatological diseases. The misuse of topical medicines for inappropriate indications and an extended period may result in cutaneous adverse drug reactions (ADR). Aims We conducted this study to observe demographic parameters, commonly misused topical medicines, various clinical patterns of cutaneous ADR, and source of drug prescription among study participants. Materials and methods This cross-sectional observational study was conducted from October 2021 to May 2022 at the dermatology outpatient department (OPD) of a tertiary care center. All patients who presented with worsening pre-existing skin diseases or the development of skin disease after the topical application of some cream or ointment were included in the study with written informed consent. A detailed history was taken, and a clinical examination was done. Results We detected 200 cases (1.62%) of cutaneous ADR out of 12,346 OPD patients in the eight-month study period. The most common age group was 21-30 years (30%). Most of the patients had used topical medicines for fungal infections (76%). The most commonly used topical medication was a fixed drug combination (FDC) of steroid, antifungal, and antibacterial agents (40%). Tinea incognito (36%) was the most common cutaneous ADR noted. Conclusion This study shows that misuse of topical medications is rampant in our community because of their free and easy availability. There is an urgent requirement for strict regulations over the manufacturing, sales, and marketing of over-the-counter (OTC) topical medications to reduce the incidence of cutaneous ADR.
