Adapting SMS-Based Pharmacovigilance Strategies From Tanzania to the Philippine ART Program

This letter comments on the study by Masika et al, which demonstrated the feasibility of SMS reminders to improve adverse drug reaction (ADR) reporting among adults on antiretroviral therapy (ART) in Tanzania. Their findings show how mobile messaging can enhance patient awareness and strengthen pharmacovigilance in resource-limited settings. This commentary considers the relevance of this approach for the Philippines, where ADR underreporting persists due to limited digital tools, uneven facility resources, and low patient engagement. With mobile phone penetration exceeding 130%, an SMS-based system could provide an accessible and scalable method for supporting timely ADR reporting among people living with HIV. Adapting the Tanzanian model, while ensuring cultural appropriateness, confidentiality, and integration with national reporting mechanisms, may help address gaps in treatment monitoring and contribute to a more responsive, data-driven ART program.
