Oligosol (Sodium Selenite)

Sodium selenite, the active ingredient in Oligosol, is a selenium supplement presented as a nutritional supplement for oral and sublingual use. It supports normal selenium status in the general population. GNH USA supplies Oligosol as a licensed, GDP-compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide.

Oligosol provides selenium, a trace element involved in antioxidant and thyroid pathways. - Selenium deficiency: helps restore normal selenium levels in individuals with inadequate dietary intake. - Oxidative stress: supports activity of antioxidant enzymes such as glutathione peroxidase. - Thyroid function: contributes to the conversion of thyroid hormones by providing necessary cofactor.

Sodium selenite may cause adverse reactions, which are generally dose‑dependent.

Common Side Effects: - Nausea: mild gastrointestinal upset. - Metallic taste: transient oral sensation. - Diarrhea: loose stools. - Headache: mild cranial discomfort.

Serious or Rare Side Effects: - Selenosis: chronic excess leading to hair loss, nail brittleness, and skin lesions. - Allergic reaction: rash, itching, or swelling. - Severe gastrointestinal irritation: vomiting, abdominal pain.

When using Oligosol, consider the following precautions to ensure safe administration. - Dosage adjustment: tailor dose based on individual selenium status and dietary intake. - Renal impairment: monitor because reduced clearance may increase exposure. - Pregnancy and lactation: use only if benefits outweigh potential risks. - Concurrent antioxidant therapy: assess for possible additive effects. - Avoid excessive intake: do not exceed recommended dietary allowance without medical supervision. - Store at ambient temperature: keep below 25 °C, protect from moisture and direct sunlight.

Sodium selenite can interact with certain medicines and nutrients.

Major Interactions (Avoid): - Anticoagulants (e.g., warfarin): selenium may potentiate anticoagulant effect, increasing bleeding risk. - Chemotherapy agents (e.g., cisplatin): high selenium may interfere with drug efficacy.

Moderate Interactions (Monitor Closely): - Vitamin C: high doses may reduce selenium absorption. - Zinc supplements: competitive absorption may alter selenium status. - Thyroid hormone replacement (levothyroxine): selenium can affect hormone conversion, requiring monitoring.
