Alfacalcidol
About Alfacalcidol
Alfacalcidol is an oral medicine prescribed to help regulate calcium and phosphate levels in the body, which are vital for maintaining strong, healthy bones. It is commonly used to treat bone diseases in people with kidney problems, bone thinning, or gland disorders. By supporting proper bone mineralization, this medication helps prevent painful bone complications and fractures.
To get the most benefit, you should take Alfacalcidol consistently at the same time every day, exactly as directed by your healthcare provider. This oral medicine can be taken with or without food, swallowed whole with a glass of water. Adopting a balanced diet with a steady intake of calcium and participating in gentle, doctor-approved weight-bearing exercises will further support your bone health.
While taking this medication, some people may experience mild side effects like headache, skin rash, or minor stomach discomfort. However, you must contact your doctor immediately if you face specific serious side effects, particularly signs of high calcium levels such as persistent nausea, vomiting, severe constipation, or extreme thirst.
Do not take this if you already have high levels of calcium or phosphate in your blood, or if you have a known sensitivity to Vitamin D products. Before starting this medicine, talk to your doctor if you have a history of kidney stones, liver disease, or heart conditions, as your treatment may require careful monitoring.
Certain medicines, alcohol, and lifestyle habits can interact with Alfacalcidol, potentially altering its effects or increasing the risk of high calcium levels. If you are pregnant, breastfeeding, or an elderly individual, consult your doctor before using this medicine to ensure it is safe for your specific health needs.
Uses of Alfacalcidol
Vitamin D Deficiency: Alfacalcidol helps replenish vitamin D levels by converting to calcitriol (Vitamin D3) and enhancing calcium absorption.
Hypocalcaemia: Alfacalcidol helps raise blood calcium levels by stimulating calcium absorption from the intestine and reabsorption from the bones and kidneys.
Osteomalacia (in adults) or Rickets (in children): Alfacalcidol helps strengthen bones by improving calcium and phosphate absorption and promoting bone mineralisation (deposition of minerals in bone tissue).
Hyperparathyroidism: Alfacalcidol helps suppress excess parathyroid hormone (PTH) levels, which can cause bones to weaken.
Hypoparathyroidism: Alfacalcidol compensates for low PTH levels by maintaining calcium and phosphate balance in the body.
Renal Osteodystrophy: Alfacalcidol helps manage this condition by regulating calcium, phosphate, and parathyroid hormone (PTH) levels, thereby improving bone quality and reducing fractures and pain.

Drug Interactions
Drug-Drug Interactions
- Thiazide diuretics (water pills): May increase the risk of dangerously high blood calcium levels when combined with Alfacalcidol.
- Cardiac glycosides (e.g., digoxin): High calcium levels caused by Alfacalcidol can increase the risk of serious, irregular heartbeats while using these heart medications.
- Anticonvulsants (e.g., phenytoin, carbamazepine): May reduce the effectiveness of Alfacalcidol, requiring your doctor to consider gradually increasing your dose.
- Bile acid sequestrants (e.g., cholestyramine): Can interfere with the absorption of Alfacalcidol, meaning they should be taken several hours apart.
Drug-Food Interactions
- High-calcium foods: Consuming excessive amounts of dairy or calcium-fortified foods without medical supervision can lead to elevated blood calcium levels.
Drug-Disease Interactions
- Hypercalcemia: Do not take this medication if you currently have high levels of calcium in your blood, as it will worsen the condition.
- Kidney stones: Use with caution, as elevated calcium levels can increase the risk of developing mineral deposits in the kidneys.
- Severe liver damage: Because Alfacalcidol relies on liver enzymes for conversion to its active form, severe liver disease may reduce its effectiveness.

Patients Concern
Disease/Condition Glossary
Vitamin D deficiency: When a person cannot get enough Vitamin D through food and exposure to sunlight, it leads to vitamin D deficiency. It often leads to thin, brittle or misshapen bones.
Renal Osteodystrophy: It is a bone disease that occurs when the kidneys fail to maintain the blood's calcium and phosphorus levels. It typically occurs in individuals with kidney disease and patients undergoing dialysis treatment.
Hypocalcaemia: It is a condition caused by low levels of calcium in the blood. The lack of vitamin D can cause hypocalcaemia.
Osteomalacia/Rickets: A disease caused by softening and weakening of bones in children due to inadequate vitamin D.
Hypoparathyroidism: It is a disease characterised by low levels of parathyroid hormone. This can cause low calcium levels and trigger tetany (muscle cramps, spasms or tremors).
Hyperparathyroidism: It is a condition in which one or more of your parathyroid glands become overactive and release high parathyroid hormone levels. This condition leads to hypercalcemia (high levels of calcium in the blood).
FAQs
Alfacalcidol is used to treat low blood calcium and phosphate levels. It effectively treats Vitamin D deficiency, renal osteodystrophy (changes in bone caused by kidney failure), hyperparathyroidism (parathyroid glands make high levels of calcium in the body), hypoparathyroidism (parathyroid glands make low levels of calcium in the body), hypocalcaemia (low levels of calcium), and rickets or osteomalacia (softening or deforming of bones due to lack of calcium).
Alfacalcidol is a dietary supplement that treats low levels of calcium and phosphate in the blood. It consists of Alfacalcidol, an analogue of Vitamin D. When you do not get enough Vitamin D from food sources and sunlight exposure, Alfacalcidol helps balance those low levels.
If you miss a dose, take it as soon as you remember. However, if it is time for the next scheduled dose, skip the missed dose and follow your usual dosage.
