Alfacalcidol questions

How does Alfacalcidol differ from regular vitamin D?

Alfacalcidol is a precursor to active vitamin D, allowing for easier regulation of calcium without the need for kidney conversion.

Can Alfacalcidol be used in pregnant pets?

Use with caution and only under veterinary supervision due to potential risks to the fetus.

How long does it take to see improvements?

Effects can be seen within a few weeks, but regular monitoring is essential.

Can Alfacalcidol be given with food?

Full drug detail

Overview

Alfacalcidol is a vitamin D analog used to manage calcium levels in pets, particularly in cases of renal insufficiency or hypocalcemia. It helps in the synthesis of active vitamin D, aiding calcium absorption and bone health.

How It Works

Alfacalcidol is metabolized in the liver to calcitriol, the active form of vitamin D. This enhances intestinal absorption of calcium and phosphate, promoting bone mineralization and managing parathyroid hormone levels.

Uses & Indications

Alfacalcidol is primarily used to treat:

  • Hypocalcemia
  • Renal osteodystrophy
  • Hyperparathyroidism

Dosage Guidelines

Consult a veterinarian for precise dosing, as it can vary based on the animal's condition and response.

Dogs

  • Small Dogs: 0.02-0.05 mcg/kg once daily
  • Medium Dogs: 0.05-0.1 mcg/kg once daily
  • Large Dogs: 0.1-0.2 mcg/kg once daily

Cats
