Generic: TRANEXAMIC ACID
Antifibrinolytic Agent [EPC]
1 INDICATIONS AND USAGE Tranexamic acid injection is indicated in patients with hemophilia for short-term use (2 to 8 days) to reduce or prevent hemorrhage and reduce the need for replacement therapy during and following tooth extraction.

5 WARNINGS AND PRECAUTIONS Risk of Thrombosis with Concomitant Use of Factor IX: Avoid concomitant use. ( 5.2 ) Seizures: Inadvertent injection into neuraxial system may result in seizures. ( 5.3 ) Hypersensitivity Reactions: In case of severe reaction, discontinue use and seek immediate medical attention. ( 5.4 ) Visual Disturbances: Visual or ocular adverse effects may occur. Discontinue use if visual or ocular symptoms occur. ( 5.5 ) Dizziness: Advise patients not to drive if dizziness occurs ( 5.6 ) 5.1 Risk of Medication Errors Due to Incorrect Route of Administration Tranexamic acid injection is for intravenous use only. Serious, including fatal, adverse reactions including seizures and cardiac arrythmias have occurred when tranexamic acid injection was inadvertently administered via the neuraxial route. Confirm the correct route of administration for tranexamic acid injection and avoid confusion with other injectable solutions that might be administered at the same time as tranexamic acid injection. Clearly label syringes containing tranexamic acid injection with the intravenous route of administration. 5.2 Thromboembolic Risk Tranexamic acid injection is contraindicated in patients with active intravascular clotting. Tranexamic acid is an antifibrinolytic and may increase the risk of thromboembolic events. Venous and arterial thrombosis or thromboembolism has been reported in patients treated with tranexamic acid injection. Avoid concomitant use of tranexamic acid injection and medical products that are pro-thrombotic, as the risk of thrombosis may be increased. These medications include but are not limited to, Factor IX Complex concentrates, Anti-inhibitor Coagulant concentrates, and hormonal contraceptives [ see Drug Interactions (7.1) , Use in Specific Populations (8.3) ]. 5.3 Seizures Tranexamic acid injection may cause seizures, including focal and generalized seizures. The most common setting for tranexamic acid-induced seizures has been during cardiovascular surgery (a setting in which tranexamic acid injection is not FDA-approved and which uses doses of up to 10-fold higher than the recommended human dose and in patients inadvertently given tranexamic acid via the neuraxial route). Tranexamic acid injection is contraindicated for neuraxial administration (i.e., epidural, intrathecal). Consider dose reduction during surgery and dose adjustments for patients with clinical conditions such as renal dysfunction. Closely monitor the patient during surgery. Consider electroencephalogram (EEG) monitoring for patients with history of seizures or who experience myoclonic movements, twitching, or show evidence of focal seizures. Discontinue tranexamic acid injection if seizures occur. 5.4 Hypersensitivity Reactions Cases of hypersensitivity reactions, including anaphylactic reactions, have occurred with use of intravenous tranexamic acid. Discontinue treatment with tranexamic acid injection if serious reaction occurs, provide appropriate medical management, and do not restart treatment. Tranexamic acid injection is contraindicated in patients with a history of hypersensitivity to tranexamic acid. 5.5 Visual Disturbances Although not seen in humans, focal areas of retinal degeneration have been observed in cats and dogs following oral or intravenous tranexamic acid at doses between 250 to 1600 mg/kg/day (1.6 to 22 times the recommended usual human dose based on body surface area) from 6 days to 1 year. No retinal changes have been observed in eye examinations of patients treated with tranexamic acid for up to 8 years. Patients expected to be treated for greater than 3 months may consider ophthalmic monitoring including visual acuity and optical coherence tomography at regular intervals. Discontinue tranexamic acid injection if changes in ophthalmological examination occurs. 5.6 Dizziness Tranexamic acid injection may cause dizziness. Concomitant use of other drugs that may also cause dizziness may worsen this effect. Advise patients to avoid driving or using machines until they know how tranexamic acid injection affects them.

Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. Gastrointestinal disturbances (nausea, vomiting, diarrhea) may occur and may resolve with dose-reduction. Allergic dermatitis and giddiness have been reported. Hypotension has been reported when intravenous injection is too rapid. Thromboembolic events (e.g., deep vein thrombosis, pulmonary embolism, cerebral thrombosis, acute renal cortical necrosis, and central retinal artery, vein obstruction and cases associated with concomitant use of combination hormonal contraceptives) have been rarely reported in patients receiving tranexamic acid for indications other than hemorrhage prevention in patients with hemophilia. Convulsion, chromatopsia, and visual impairment have also been reported. Anaphylaxis or anaphylactoid reactions have been reported that are suggestive of a causal relationship.
