What should you know about oral tranexamic acid melasma?

Melasma causes darker, often symmetrical patches on areas such as the cheeks, forehead, upper lip, or jaw. A dermatologist first checks that the pattern fits melasma and considers triggers such as sunlight, heat, hormones, and irritating skin products.

Tranexamic acid is not a bleaching agent. Its proposed role in melasma relates to pathways that influence pigment activity. Because oral medicine circulates through the body, a history of clotting, kidney disease, visual symptoms, pregnancy, and current medicines affects the decision.

Arrange a dermatology consultation before using tablets. Bring a list of medicines and contraception, mention previous clots or clotting disorders, and describe any migraine or vision symptoms. Continue the sun-protection plan advised for your skin, since ultraviolet and visible light can deepen melasma.

Keep photographs in consistent lighting if your clinician recommends monitoring. Improvement can be gradual, and the plan may combine topical treatment with sun protection. See Tranexamic Acid for Melasma for treatment details and Tranexamic Acid for background on the medicine.

Seek urgent help for chest discomfort, breathlessness, coughing blood, one-sided leg pain or swelling, sudden weakness, a severe unfamiliar headache, or sudden vision changes. Report facial swelling, wheezing, or a widespread rash without delay.

Ask how the diagnosis was made, why oral treatment is being considered, what alternatives exist, how your risks will be checked, and how recurrence will be managed.
