Introduction There is ambiguity regarding usage of tranexamic acid for melasma in India, be it in its pre-administration evaluation, administration route, dosing or monitoring. Hence, we conducted this study to understand various tranexamic-acid prescribing patterns and provide practical guidelines. Materials and methods A Google-form-based questionnaire (25-questions) was prepared based on the key areas identified by experts from the Pigmentary Disorders Society, India and circulated to practicing dermatologists across the country. In rounds 2 and 3, the questionnaire was re-presented to the same group of experts and their opinions were sought. The results of the practitioners' survey were denoted graphically alongside, to guide them. Consensus was deemed when at least 80% of respondents chose an option. Results The members agreed that history pertaining to risk factors for thromboembolism, cardiovascular and menstrual disorders should be sought in patients being started on oral tranexamic-acid. Baseline coagulation profile should be ordered in all patients prior to tranexamic-acid and more exhaustive investigations such as complete blood count, liver function test, protein C and S in patients with high risk of thromboembolism. The preferred oral dose was 250 mg orally twice daily, which can be used alone or in combination with topical hydroquinone, kojic acid and sunscreen. Repeated dosing of tranexamic-acid may be required for those relapsing with melasma following initial tranexamic-acid discontinuation. Coagulation profile should ideally be repeated at three monthly intervals during follow-up, especially in patients with clinically higher risk of thromboembolism. Treatment can be stopped abruptly post improvement and no tapering is required. Limitation This study is limited by the fact that open-ended questions were limited to the first general survey round. Conclusion Oral tranexamic-acid provides a valuable treatment option for melasma. Frequent courses of therapy may be required to sustain results and a vigilant watch is recommended for hypercoagulable states during the course of therapy. [ABSTRACT FROM AUTHOR] |
