Hello,
I have reviewed your reported results:
Vitamin B12: below 148 pg/mL â Significant deficiency.
Vitamin D: 16.6 ng/mL â Deficient.
HbA1c: 5.7% â At the prediabetes threshold.
ALT 57 and ALP 159 U/L â Mildly elevated, requiring clinical correlation.
Vitamin B12 replacement injections are appropriate for significant deficiency, and an alternate-day loading schedule is commonly used.
However, I am concerned about the prescribed Arachitol 6L injection schedule.
If Arachitol 6L contains 600,000 IU of vitamin D3 per injection, taking it weekly for four weeks would total 2.4 million IU, which is substantially higher than usual vitamin D replacement regimens and may increase the risk of vitamin D toxicity and hypercalcaemia.
Next Steps
Confirm the exact strength and schedule of Arachitol 6L with your prescribing doctor before receiving the injections. For uncomplicated
vitamin D deficiency, commonly used regimens include 50,000â60,000 IU orally once weekly for 6â8 weeks, followed by maintenance therapy. Continue
B12 replacement as prescribed, but discuss the underlying cause and whether maintenance doses are required. Consider checking serum
calcium,
creatinine, and repeat vitamin D levels after treatment, as clinically indicated. Repeat
liver function tests and assess possible causes of mildly elevated ALT and ALP.
Health Tips
My recommendation: Your
vitamin deficiencies require treatment, but four weekly injections of 600,000 IU
vitamin D should be clarified before proceeding. This is not a routine replacement schedule for a vitamin D level of 16.6 ng/mL. Avoid combining vitamin D injections with additional high-dose supplements without medical supervision. Excessive vitamin D can cause high blood
calcium, leading to nausea, vomiting, constipation, excessive thirst, frequent urination, and
kidney complications. If you have already received high-dose injections, inform your doctor and arrange calcium and kidney function assessment. With appropriate dosing and monitoring, both deficiencies are generally treatable. Wishing you good health!
