the answer is not simple yes or no dear, injection of 6 lakh unit will give sufficient rise but should be rechecked after 4 weeks to check adequecy and note more dose of vit d have side effect unlike water soluble bitamin b which can be taken extra but vit a and d overdose is not advised so without consultation dont take additional dose
Next Steps
recheck if doubt after 4 to 6 weeks at least , i know the cost of test is high but without consultation dont take additional injection of vit d because 6 lakh dose is high
Health Tips
