St. John's Wort is known to affect the metabolism of several drugs through enzyme induction and transporter inhibition.
Major Interactions (Avoid): - Oral contraceptives: reduced plasma levels leading to contraceptive failure. - Anticoagulants (e.g., warfarin): decreased effect increasing clot risk. - Immunosuppressants (e.g., cyclosporine, tacrolimus): lowered concentrations causing graft rejection. - Antiretroviral agents (e.g., protease inhibitors): diminished efficacy of HIV therapy. - Serotonergic antidepressants (e.g., SSRIs, SNRIs, MAOIs): heightened risk of serotonin syndrome.
Moderate Interactions (Monitor Closely): - Antidepressants with serotonergic activity: monitor for serotonin syndrome symptoms. - Antiepileptic drugs (e.g., carbamazepine, phenytoin): possible altered levels. - Statins metabolised by CYP3A4: potential reduction in lipid‑lowering effect. - Beta‑blockers (e.g., propranolol): may experience decreased efficacy. - Caffeine: increased metabolism may reduce stimulant effect.
