What does Sodium Selenite interact with?
Sodium selenite can interact with several medicines, requiring attention to avoid reduced efficacy or increased toxicity.
Major Interactions (Avoid): - Antithyroid drugs (e.g., propylthiouracil): may diminish therapeutic effect of selenium on thyroid function. - High-dose vitamin C supplements: can reduce selenium absorption. - Anticoagulants (e.g., warfarin): selenium may potentiate anticoagulant effect, increasing bleeding risk.
Moderate Interactions (Monitor Closely): - Levothyroxine: concurrent use may require thyroid function monitoring. - Chemotherapy agents (e.g., cisplatin): selenium may affect drug toxicity profile. - Statins: monitor for muscle‑related side effects.
