Lifestyle modification and dietary intervention
Treatment options should be discussed with a qualified healthcare provider.
Hydroxychloroquine
Immunomodulatory agent with antithrombotic properties, often used as adjunctive therapy in antiphospholipid syndrome. May reduce antibody levels and thrombotic risk.
Additional treatment options
Statin therapy
HMG-CoA reductase inhibitors with anti-inflammatory and antithrombotic properties. May provide additional vascular protection beyond lipid lowering in high-risk patients.
medicationThrombosis surveillance
Regular clinical assessment for signs of venous or arterial thrombosis including D-dimer testing and vascular imaging when indicated. Early detection allows prompt treatment escalation.
