What should you know about tranexamic acid dermatology?

Melasma causes patches of darker colour, often on the face. Tranexamic acid may be included in a treatment plan because it can influence pathways involved in pigment production and inflammation. A dermatologist may choose a topical or oral approach, depending on the pattern, skin sensitivity, health history, and other treatments.

Pigmentation can also reflect sun exposure, irritation, hormones, or another skin condition. Diagnosis matters before treatment. The medicine is not a substitute for daily sun protection, gentle skin care, or review of a changing or unusual mark.

Use tranexamic acid only in the form and schedule chosen for you. Tell the dermatologist if you have had a blood clot, kidney disease, migraine with visual symptoms, abnormal bleeding, or a change in vision. Share a complete list of medicines, including hormonal contraception and supplements.

Avoid adding strong lightening products or irritating procedures without checking first, since inflammation can worsen uneven colour. Keep follow-up appointments so the clinician can assess response and reconsider the plan. Read more at [Tranexamic Acid for Melasma](/treatments/medical-dermatology/tranexamic-acid-for-melasma/).

Get urgent help for chest pain, breathlessness, coughing blood, a painful swollen leg, sudden weakness, trouble speaking, or sudden vision loss. These can indicate a serious reaction or clot and need immediate assessment.

Contact your clinician promptly for new visual symptoms, unusual bleeding, severe headache, facial swelling, or a rapidly changing pigmented mark. Do not continue an oral treatment while waiting for advice if the prescriber told you to stop for a warning symptom.

Ask whether the diagnosis is melasma, which route is suitable, how sun protection fits the plan, when improvement should be reviewed, and which symptoms require stopping treatment. Ask how pregnancy, breastfeeding, clot history, and contraception affect the decision.
