Special Precautions
Lixiana 15 mg is not indicated as monotherapy, as it may result in decreased efficacy. It is only indicated in the process of switching from Lixiana 30 mg (patients with one or more clinical factors for increased exposure; see table 10) to VKA, together with an appropriate VKA dose (see Table 11, Dosage & Administration).
Haemorrhagic risk: Edoxaban increases the risk of bleeding and can cause serious, potentially fatal bleeding. Lixiana, like other anticoagulants, is recommended to be used with caution in patients with increased risk of bleeding. Lixiana administration should be discontinued if severe haemorrhage occurs (see Adverse Reactions and Overdosage).
In the clinical studies mucosal bleedings (e.g. epistaxis, gastrointestinal, genitourinary) and anaemia were seen more frequently during long term edoxaban treatment compared with VKA treatment. Thus, in addition to adequate clinical surveillance, laboratory testing of haemoglobin/haematocrit could be of value to detect occult bleeding, as judged to be appropriate.
Several sub-groups of patients, as detailed as follows, are at increased risk of bleeding. These patients are to be carefully monitored for signs and symptoms of bleeding complications and anaemia after initiation of treatment (see Adverse Reactions). Any unexplained fall in haemoglobin or blood pressure should lead to a search for a bleeding site.
The anticoagulant effect of edoxaban cannot be reliably monitored with standard laboratory testing. A specific anticoagulant reversal agent for edoxaban is not available (see Overdosage).
Haemodialysis does not significantly contribute to edoxaban clearance (see Pharmacology: Pharmacokinetics under Actions).
Elderly: The co-administration of Lixiana with ASA in elderly patients should be used cautiously because of a potentially higher bleeding risk (see Interactions).
Discontinuation for surgery and other interventions: If anticoagulation must be discontinued to reduce the risk of bleeding with surgical or other procedures, Lixiana should be stopped as soon as possible and preferably at least 24 hours before the procedure.
In deciding whether a procedure should be delayed until 24 hours after the last dose of Lixiana, the increased risk of bleeding should be weighed against the urgency of the intervention. Lixiana should be restarted after the surgical or other procedures as soon as adequate haemostasis has been established, noting that the time to onset of the edoxaban anticoagulant therapeutic effect is 1 - 2 hours. If oral medicinal products cannot be taken during or after surgical intervention, consider administering a parenteral anticoagulant and then switch to oral once daily Lixiana (see Dosage & Administration).
Interaction with other medicinal products affecting haemostasis: Concomitant use of medicines affecting haemostasis may increase the risk of bleeding. These include acetylsalicylic acid (ASA), P2Y12 platelet inhibitors, other antithrombotic agents, fibrinolytic therapy, selective serotonin reuptake inhibitors (SSRIs) or serotonin norepinephrine reuptake inhibitors (SNRIs), and chronic nonsteroidal anti-inflammatory drugs (NSAIDs) (see Interactions).
Prosthetic heart valves and moderate to severe mitral stenosis: Edoxaban has not been studied in patients with mechanical heart valves, in patients during the first 3 months after implantation of a bioprosthetic heart valve, with or without atrial fibrillation, or in patients with moderate to severe mitral stenosis. Therefore, use of edoxaban is not recommended in these patients.
Haemodynamically unstable PE patients or patients who require thrombolysis or pulmonary embolectomy: Lixiana is not recommended as an alternative to unfractionated heparin in patients with pulmonary embolism who are haemodynamically unstable or may receive thrombolysis or pulmonary embolectomy since the safety and efficacy of edoxaban have not been established in these clinical situations.
Patients with active cancer: Efficacy and safety of edoxaban in the treatment and/or prevention of VTE in patients with active cancer have not been established.
Patients with antiphospholipid syndrome: Direct acting Oral Anticoagulants (DOACs) including edoxaban are not recommended for patients with a history of thrombosis who are diagnosed with antiphospholipid syndrome. In particular for patients that are triple positive (for lupus anticoagulant, anticardiolipin antibodies, and anti-beta 2-glycoprotein I antibodies), treatment with DOACs could be associated with increased rates of recurrent thrombotic events compared with vitamin K antagonist therapy.
Laboratory coagulation parameters: Although treatment with edoxaban does not require routine monitoring, the effect on anticoagulation can be estimated by a calibrated quantitative anti-Factor Xa assay which may help to inform clinical decisions in particular situations as, e.g. overdose and emergency surgery (see also Pharmacology: Pharmacokinetics under Actions).
Edoxaban prolongs standard clotting tests such as prothrombin time (PT), INR, and activated partial thromboplastin time (aPTT) as a result of FXa inhibition. Changes observed in these clotting tests at the expected therapeutic dose are, however, small, subject to a high degree of variability, and not useful in monitoring the anticoagulation effect of edoxaban.
Effects on ability to drive and use machines: Lixiana has no or negligible influence on the ability to drive and use machines.
Renal impairment: The plasma AUC for subjects with mild (CrCL > 50 - 80 mL/min), moderate (CrCL 30 - 50 mL/min) and severe (CrCL < 30 mL/min but not undergoing dialysis) renal impairment was increased by 32%, 74%, and 72%, respectively, relative to subjects with normal renal function (see Dosage & Administration for dose reduction).
In patients with end stage renal disease or on dialysis, Lixiana is not recommended (see Dosage & Administration and Pharmacology: Pharmacokinetics under Actions).
Renal function in NVAF: A trend towards decreasing efficacy with increasing creatinine clearance was observed for edoxaban compared to well-managed warfarin (see Pharmacology: Pharmacodynamics under Actions). Therefore, edoxaban should only be used in patients with NVAF and high creatinine clearance after a careful evaluation of the individual thromboembolic and bleeding risk.
Assessment of renal function: CrCL should be monitored at the beginning of the treatment in all patients and afterwards when clinically indicated (see Dosage & Administration).
Hepatic impairment: Lixiana is not recommended in patients with severe hepatic impairment (see Dosage & Administration and Pharmacology: Pharmacokinetics under Actions).
Lixiana should be used with caution in patients with mild or moderate hepatic impairment (see Dosage & Administration).
Patients with elevated liver enzymes (ALT/AST > 2 x ULN) or total bilirubin ≥ 1.5 x ULN were excluded in clinical trials. Therefore Lixiana should be used with caution in this population (see Dosage & Administration and Pharmacology: Pharmacokinetics under Actions). Prior to initiating Lixiana, liver function testing should be performed.
Periodic hepatic monitoring is recommended for patients on Lixiana treatment beyond 1 year.
