Intralesional tranexamic acid: what to know

Tranexamic acid helps reduce the breakdown of blood clots and is also used in selected dermatology plans for pigmentation. Intralesional treatment places a small amount directly into the area being treated rather than applying it broadly to the skin. The injection technique, number of sessions, spacing, and expected response vary with the condition and skin type. It is not suitable for every mark, so the diagnosis should be confirmed before treatment.

Ask the treating clinician what the injection is intended to improve, how many visits may be needed, and what other options exist. Share your history of blood clots, clotting disorders, kidney problems, seizures, allergies, pregnancy, and medicines that affect clotting. After treatment, follow the aftercare instructions, avoid picking or rubbing the area, and protect treated skin from strong sunlight. You may discuss broader information about Tranexamic Acid, or condition-specific options for Tranexamic Acid for Melasma.

Mild tenderness, redness, or swelling near an injection can occur, but contact the clinic if the reaction is worsening, spreading, blistered, or associated with marked pain. Seek emergency help for trouble breathing, facial swelling, sudden weakness, chest pain, severe headache, or a painful swollen leg. These symptoms may signal a serious reaction or a clot and should not be managed by waiting for the next appointment.

Ask how the diagnosis was confirmed, why an intralesional route is being recommended, and how response will be judged. Check whether your medical history or medicines change the plan, what temporary skin changes to expect, and who to contact if symptoms develop after treatment.
