Alfa-D Tablets: Uses, Dosage, Side Effects, Benefits and Precautions
Alfa-D tablets are a medicine containing alfacalcidol, a vitamin D analogue that helps the body regulate calcium and phosphate levels. Alfa-D is available in different strengths, including 0.25 mcg, 0.5 mcg and 1 mcg, and is manufactured by Platinum Pharmaceuticals in Pakistan.
Doctors may prescribe alfacalcidol for certain conditions involving calcium and vitamin D metabolism, including some bone disorders, hypoparathyroidism, osteomalacia and bone disease associated with chronic kidney problems.
What Are Alfa-D Tablets?
Alfa-D is the brand name for tablets containing alfacalcidol. Alfacalcidol is a synthetic vitamin D analogue that is converted in the liver into its active form, helping the body manage calcium and phosphate metabolism.
Alfa-D Tablet Composition
The active ingredient is:
- Alfacalcidol 0.25 mcg
- Alfacalcidol 0.5 mcg
- Alfacalcidol 1 mcg
The exact strength prescribed depends on the patient's condition and response to treatment.

How Does Alfa-D Work?
Alfacalcidol is converted in the liver into the active vitamin D metabolite. This helps increase the body's absorption and regulation of calcium and phosphate, which are important for normal bone mineralization and other body functions.
Alfa-D Tablets Uses
Alfa-D may be prescribed for conditions associated with abnormal calcium or vitamin D metabolism.
1. Bone Disorders
Alfacalcidol can be used as part of treatment for certain bone disorders in which calcium and vitamin D metabolism is disturbed.
2. Osteomalacia
Osteomalacia is a condition in which bones become softer because of impaired mineralization. Alfacalcidol may be prescribed when appropriate to help correct calcium and phosphate metabolism.
3. Hypoparathyroidism
Doctors may use alfacalcidol in patients with hypoparathyroidism, a condition that can lead to abnormal calcium regulation.
4. Kidney-Related Bone Disease
Alfa-D may be prescribed for bone disease associated with chronic kidney failure, where vitamin D and mineral metabolism can become abnormal.
5. Certain Forms of Rickets
Alfacalcidol may also be used in selected cases of vitamin-D-dependent or vitamin-D-resistant rickets under medical supervision.
Alfa-D Tablets Dosage
The correct dose of Alfa-D is not the same for everyone. It depends on the medical condition, age, calcium levels, kidney function and response to treatment.
How Should Alfa-D Be Taken?
Take Alfa-D exactly as prescribed by your doctor. Do not increase or decrease the dose yourself.
Because alfacalcidol can affect calcium levels, doctors may monitor blood calcium and other relevant laboratory values during treatment.
What If You Miss a Dose?
If you forget a dose, take it when you remember unless it is almost time for your next dose. Do not take two doses together to make up for a missed dose.

Alfa-D Tablets Side Effects
Like other medicines, Alfa-D may cause side effects in some people. One important concern with excessive alfacalcidol is high calcium levels in the blood (hypercalcaemia).
Possible Side Effects
Some symptoms associated with excessive calcium may include:
- Nausea or stomach discomfort
- Constipation
- Abdominal pain
- Dry mouth
- Dizziness
- Weakness or tiredness
- Increased thirst
- Palpitations
Severe or persistent symptoms should be discussed with a doctor. The manufacturer's information specifically warns that overdose can cause hypercalcaemia.
When to Seek Medical Help
Seek medical advice promptly if you develop symptoms suggesting significantly elevated calcium levels, particularly persistent vomiting, severe weakness, marked thirst, confusion, or abnormal heart palpitations.
Alfa-D Tablets Precautions
Before taking Alfa-D, tell your doctor about your medical history and all medicines or supplements you are using.
Calcium Levels Should Be Monitored
Alfacalcidol can increase calcium levels, so medical monitoring may be required during treatment. Taking additional calcium or vitamin D products without medical advice may increase the risk of excessive calcium.
Kidney Problems
Patients with kidney disease may require specialist monitoring because calcium and phosphate balance can be complicated in chronic kidney disease.
Pregnancy and Breastfeeding
The manufacturer's leaflet states that the safety of Alfa-D during pregnancy has not been established and that it should be used during pregnancy only when the expected therapeutic benefit outweighs potential risk. Pregnant or breastfeeding women should therefore consult their doctor before using it.
Alfa-D Drug Interactions
Tell your doctor or pharmacist about all medicines you take.
The manufacturer's information specifically advises caution with:
Magnesium-Containing Products
Concomitant use with magnesium-containing preparations may increase the risk of high magnesium levels in some patients.
Digitalis Medicines
Alfacalcidol should be used carefully with digitalis preparations because changes in calcium levels can be clinically important.
Alfa-D Tablets Overdose
Taking more Alfa-D than prescribed can increase the risk of hypercalcaemia.
Possible symptoms can include abdominal discomfort, constipation, dry mouth, dizziness, weakness and palpitations. If you suspect that you have taken too much, contact a healthcare professional promptly.
How to Store Alfa-D Tablets
According to the manufacturer's information, Alfa-D tablets should be:
- Stored below 30°C
- Kept in a dry place
- Protected from light
- Kept out of reach of children
