Common use

Medex is primarily indicated for reducing the risk of stroke and systemic embolism in patients with non-valvular atrial fibrillation. It is extensively used for prophylaxis of deep vein thrombosis following hip or knee replacement surgery, with demonstrated efficacy in preventing venous thromboembolism in adult patients. The medication is also approved for treatment of deep vein thrombosis and pulmonary embolism, as well as reduction in risk of recurrent venous thromboembolism. Healthcare providers frequently prescribe Medex for patients requiring extended anticoagulation therapy who have demonstrated intolerance or poor response to vitamin K antagonists. The medication has shown particular effectiveness in elderly populations and patients with moderate renal impairment where other anticoagulants may pose increased bleeding risks.

Dosage and direction

The recommended dosage of Medex is 5 mg taken orally twice daily with or without food. For patients with at least two of the following characteristics: age ≥80 years, body weight ≤60 kg, or serum creatinine ≥1.5 mg/dL, the recommended dosage is 2.5 mg twice daily. For deep vein thrombosis and pulmonary embolism treatment, the recommended dosage is 10 mg twice daily for the first 7 days, followed by 5 mg twice daily. Post-surgical thrombosis prophylaxis typically involves 2.5 mg twice daily commencing 12-24 hours after surgery. Tablets should be swallowed whole with water and not crushed or chewed. Administration timing should be consistent, approximately every 12 hours, to maintain steady-state concentrations. Dosage adjustments may be necessary based on renal function, with creatinine clearance monitoring recommended before initiation and periodically during treatment.

Precautions

Patients should be carefully monitored for signs of bleeding, including unusual bruising, prolonged bleeding from cuts, pink or brown urine, red or black stools, coughing up blood, vomiting blood, headaches, dizziness, or weakness. Regular assessment of renal function is essential, particularly in elderly patients or those with comorbid conditions that may affect renal performance. Hepatic function should be evaluated before initiation and periodically during treatment, as severe hepatic impairment may increase bleeding risk. Special caution is required when administering to patients with congenital or acquired bleeding disorders, active ulcerative gastrointestinal disease, recent brain, spinal, or ophthalmic surgery, or those with recent trauma. Patients should be advised to report any planned surgical procedures, including dental surgery, to their healthcare provider. Concomitant use of other medications affecting hemostasis requires careful risk-benefit assessment and enhanced monitoring.

Contraindications

Medex is contraindicated in patients with active pathological bleeding, severe hypersensitivity reaction to apixaban or any component of the product, and patients with severe hepatic impairment (Child-Pugh C). The medication must not be used in patients with prosthetic heart valves or those with hemodynamically significant rheumatic heart disease, particularly mitral stenosis. Concomitant administration with strong dual inhibitors of both CYP3A4 and P-glycoprotein, such as ketoconazole, itraconazole, ritonavir, or clarithromycin, is contraindicated due to significantly increased exposure. The medication is not recommended for patients with creatinine clearance <15 mL/min or those undergoing dialysis. Pregnancy and breastfeeding represent absolute contraindications due to potential fetal harm and secretion in human milk.

Possible side effect

The most common adverse reactions (>1%) include:

• Bleeding complications (major and minor)
• Nausea (2.7%)
• Elevated transaminases (1.8%)
• Anemia (1.5%)
• Rash (1.3%)
• Fatigue (1.1%)

Serious but less common side effects (<1%) may include:

• Intracranial hemorrhage
• Gastrointestinal bleeding
• Retroperitoneal hemorrhage
• Ocular bleeding
• Spinal or epidural hematoma (particularly with neuraxial anesthesia)
• Hypersensitivity reactions including anaphylaxis
• Severe skin reactions including Stevens-Johnson syndrome
• Jaundice and hepatitis
• Thrombocytopenia

Drug interaction

Medex demonstrates significant interactions with:

• Strong CYP3A4 and P-gp inhibitors: Ketoconazole, itraconazole, ritonavir, clarithromycin (increase exposure by 100-200%)
• Strong CYP3A4 and P-gp inducers: Rifampin, carbamazepine, phenytoin, St. John’s wort (decrease exposure by 50%)
• Anticoagulants: Warfarin, heparin, low molecular weight heparins (increased bleeding risk)
• Anti-platelet agents: Aspirin, clopidogrel, prasugrel (synergistic bleeding effects)
• NSAIDs: Ibuprofen, naproxen, diclofenac (increased gastrointestinal bleeding risk)
• SSRIs/SNRIs: Fluoxetine, sertraline, venlafaxine (increased bleeding tendency)
• Antifungal agents: Fluconazole, posaconazole (moderate exposure increase)

Missed dose

If a dose of Medex is missed, the patient should take the dose as soon as possible on the same day and resume the twice-daily regimen. The dose should not be doubled to make up for the missed dose. If the missed dose is not remembered until the next scheduled dose is due, only one dose should be taken. Patients should maintain their regular dosing schedule and not alter subsequent doses. Healthcare providers should educate patients about the importance of adherence and implement reminder systems if missed doses become frequent. In cases where multiple doses are missed, medical consultation is recommended to assess thrombosis risk and consider additional protective measures.

Overdose

Overdose of Medex may lead to hemorrhagic complications. There is no specific antidote for apixaban overdose. In cases of suspected overdose, immediate medical attention is required. Management strategies include:

• Discontinuation of Medex
• Symptomatic and supportive care
• Monitoring for signs of bleeding
• Assessment of hemoglobin and hematocrit
• Consideration of activated charcoal if ingestion occurred within 2-3 hours
• In life-threatening bleeding, consider prothrombin complex concentrates (PCCs), activated PCC, or recombinant Factor VIIa
• Fresh frozen plasma may be considered though limited evidence exists
• Tranexamic acid or aminocaproic acid for adjunctive management
• Hemodialysis is not effective due to high protein binding

Storage

Store Medex at controlled room temperature 20°C to 25°C (68°F to 77°F) with excursions permitted between 15°C and 30°C (59°F and 86°F). Keep in original blister packaging to protect from moisture and light. Do not remove desiccant from bottle packaging. Keep out of reach of children and pets. Do not use if the blister pack is damaged or tablets show signs of deterioration. Avoid storage in bathrooms or other areas with high humidity. Discard any unused medication after the expiration date printed on the packaging. Do not flush medications down the toilet or pour into drainage systems unless instructed to do so.
