Question

A dose of cyanocobalamin (vitamin B12) is administered via an intramuscular or deep subcutaneous injection. A typical dose is 0.1 mg/day. If the concentration of the cyanocobalamin solution is 1 mg/ml, and each vial contains 1 ml of the solution, how many days’ dose would be provided by 5 vials?

Answer 1

Ans)  Typical dose of cyanocobalamin solution is 0.1 mg/day

Cyanocobalamin solution: 1 mg/ml

1 mg = 1 ml

0.1 mg = x

x= 0.1 × 1 = 0.1 ml.

1 vial for 10 doses.

So 5 vials× 10 = 50 days dose.
