Here is a focused answer:

First-Line Drug for Heavy Menstrual Bleeding (HMB) in ITP

Tranexamic Acid (TXA) — First-Line for Symptomatic Menorrhagia

In an ITP patient with heavy menstrual bleeding, tranexamic acid is the first-line drug specifically targeting the bleeding symptom. It is an antifibrinolytic agent that inhibits plasminogen activation, stabilizing clots at the endometrial surface.

"There has been an increase in use of tranexamic acid (TXA) for mucocutaneous bleeding, menorrhagia, or epistaxis" — Rosen's Emergency Medicine

Dose: 1 g orally 3× daily during menstruation (or 1 g IV every 6–8 hours if bleeding is severe/acute).

Context: ITP-Specific vs. Bleeding-Specific Treatment

It is important to distinguish two parallel treatment targets:

Goal	Drug(s)
Control the bleeding directly	Tranexamic acid (first-line)
Raise platelet count (treat underlying ITP)	Corticosteroids (prednisone 0.5–2 mg/kg/day or dexamethasone 40 mg/day × 4 days)

The ASH ITP guidelines recommend corticosteroids as first-line for newly diagnosed ITP to raise platelet count, but for the isolated symptom of HMB, especially if the woman is not otherwise requiring ITP treatment, tranexamic acid is preferred first, often combined with:

Combined oral contraceptive pills (COCPs) — reduce menstrual blood loss by ~50%, can suppress periods entirely; often co-prescribed with TXA or used when TXA alone is insufficient
Progestin-only contraceptives (e.g., LNG-IUD, depot medroxyprogesterone) — also effective for menstrual suppression

When to Escalate

If HMB persists despite TXA ± hormonal therapy, or if other bleeding sites are present (petechiae, wet purpura), ITP-directed therapy is needed:

Corticosteroids (short course ≤6 weeks — ASH guideline)
IVIG (if rapid platelet rise needed or steroids contraindicated)
TPO receptor agonists (romiplostim, eltrombopag) for refractory/chronic ITP

Summary

Tranexamic acid is the first-line drug for heavy menstrual bleeding in ITP — it controls the bleeding without addressing platelet count. If platelet count is critically low (<30 × 10⁹/L) or other bleeding is present, add corticosteroids as first-line ITP treatment. COCPs are a complementary/alternative hormonal option for menstrual management.
