Helios (Colecalciferol)

Helios is indicated for the correction of low vitamin D levels and for supporting normal calcium balance.

• Vitamin D deficiency (insufficient serum 25‑hydroxyvitamin D).
• Hypocalcemia associated with inadequate vitamin D.
• Prevention of osteomalacia in adults.
• Support of bone health in individuals with limited sun exposure.
• Adjunct to calcium supplementation in dietary regimens.
• Maintenance of adequate vitamin D status during pregnancy and lactation, when recommended by a healthcare professional.
• Support for immune system function as part of overall nutritional health, especially in older adults.

Side effects reported with oral colecalciferol are generally mild, but rare serious reactions can occur.

Common

• Mild gastrointestinal discomfort such as nausea or abdominal bloating.
• Transient headache or fatigue.
• Slight increase in serum calcium without symptoms.
• Dry mouth or mild metallic taste.
• Mild skin dryness or itching at the site of oral administration (rare).

Serious

• Hypercalcemia presenting with nausea, vomiting, polyuria, or cardiac arrhythmia.
• Allergic reactions including rash, itching, or swelling of the face and throat.
• Kidney stones in susceptible individuals.
• Severe hypercalcemia leading to confusion, weakness, or cardiac conduction abnormalities.
• Calcific deposits in soft tissues, such as arteries or heart valves, in prolonged high-dose use.

Precautions should be considered before using Helios to ensure safe and appropriate supplementation.

• Assess serum 25‑hydroxyvitamin D and calcium levels prior to initiation.
• Use lower doses in individuals with renal impairment or hyperparathyroidism.
• Monitor for signs of hypercalcemia during prolonged therapy.
• Avoid use in patients with known hypersensitivity to vitamin D3 preparations.
• Pregnant or breastfeeding women should consult a healthcare professional before use.
• Children under 1 year of age require pediatric dosing guidance.
• Concomitant high-dose calcium supplements may increase risk of hypercalcemia.

Helios may interact with certain medications or supplements, influencing vitamin D metabolism, calcium balance, or the effectiveness of therapy. Patients should review their medication list with a healthcare professional before starting supplementation.

Avoid

• Thiazide diuretics, which can increase the risk of hypercalcemia when combined with vitamin D.
• High-dose calcium supplements without medical supervision, as they may potentiate hypercalcemia.
• Vitamin A supplements at high doses, as excess vitamin A may antagonize vitamin D activity.

Use with caution

• Anticonvulsants such as phenytoin or phenobarbital, which can accelerate vitamin D catabolism.
• Glucocorticoids, which may reduce vitamin D effectiveness.
• Orlistat, which can decrease absorption of fat‑soluble vitamins including vitamin D.
• Bisphosphonates, where concurrent high vitamin D may affect calcium homeostasis.
• Cholestyramine, which can bind fat‑soluble vitamins and reduce vitamin D absorption.
