Nexag (Tranexamic Acid)

Tranexamic Acid is used to reduce bleeding in conditions where fibrinolysis is excessive.

• Heavy menstrual bleeding (menorrhagia): reduces menstrual blood loss and improves quality of life.
• Trauma‑related bleeding: helps control hemorrhage in traumatic injuries and emergency settings.
• Surgical bleeding control: minimizes intra‑operative blood loss during various surgeries.
• Dental procedures in patients with bleeding disorders: stabilizes clot formation to prevent excessive oral bleeding.

• Tranexamic Acid works by competitively inhibiting the activation of plasminogen to plasmin, the enzyme responsible for fibrin degradation. By blocking this conversion, it reduces fibrinolysis, thereby preserving the fibrin matrix of formed clots and enhancing clot stability at sites of vascular injury. The effect is dose‑dependent and primarily localized to the plasma compartment, and does not significantly affect platelet function or coagulation factor activity.

Tranexamic Acid may cause adverse reactions, which are categorized by frequency and severity.

Common Side Effects

• Nausea: mild gastrointestinal upset.
• Headache: transient cranial discomfort.
• Diarrhea: loose stools.

Serious or Rare Side Effects

• Thromboembolic events: deep vein thrombosis or pulmonary embolism.
• Severe allergic reaction: rash, itching, swelling, or anaphylaxis.
• Renal impairment: worsening kidney function in susceptible patients.

Tranexamic Acid should be used with careful clinical assessment and monitoring.

• Assess bleeding risk: evaluate patient history before initiating therapy.
• Monitor renal function: adjust use in patients with kidney impairment.
• Avoid in active thromboembolic disease: contraindicated if patient has recent clot.
• Use with caution in pregnancy: limited data, weigh benefits vs risks.
• Review concomitant medications: consider interactions with anticoagulants and hormonal therapies.
• Store at ambient temperature: keep below 25°C in original packaging, protect from moisture.

Tranexamic Acid can interact with several drug classes, requiring attention to avoid adverse outcomes.

Major Interactions (Avoid)

• Concomitant use with pro‑coagulant agents (e.g., factor VIIa): may increase clot risk.
• Combined with hormonal contraceptives: heightened thrombotic potential.

Moderate Interactions (Monitor Closely)

• Anticoagulants (warfarin, DOACs): may reduce anticoagulant effect.
• Antiplatelet drugs (aspirin, clopidogrel): monitor for altered bleeding.
• NSAIDs: increased gastrointestinal irritation.
