Alfacalcidol
Alfacalcidol is converted by the liver to active vitamin D and is used for selected calcium and bone disorders. It is not a routine substitute for standard vitamin D supplements.
Key points
- Alfacalcidol can raise calcium and phosphate, so blood monitoring guides safe treatment.
- Other vitamin D or calcium products and some diuretics can increase toxicity risk.
- Confusion, repeated vomiting, marked weakness or an irregular heartbeat can signal severe high calcium.
Listings are for comparison and general information; suitability and supply depend on the diagnosis, clinician and pharmacy checks, laboratory monitoring and prescription requirements.
What alfacalcidol is used for
Alfacalcidol may be used in selected kidney-related mineral disorders, low-calcium states or bone conditions where active vitamin D is required. The underlying cause determines whether it is appropriate.
Important safety checks
Calcium, phosphate, kidney function and all supplements or medicines require review. Symptoms such as thirst, constipation, nausea or frequent urination can indicate rising calcium.
When to seek urgent care
Seek urgent help for severe weakness, confusion, repeated vomiting, dehydration, a fast or irregular heartbeat, collapse or very little urine.
