What is the IV:PO ratio for Levothyroxine?

0.5:1
0.75:1
1:1
1.25:1

The correct answer is: 0.75:1

The ratio for Levothyroxine, which is the amount of medication given intravenously (IV) versus orally (PO), is 0.751. This means that for every 0.75 milligrams (mg) given intravenously, 1 mg is given orally. This ratio allows for the medication to be absorbed and distributed effectively in the body. The other options, such as 0.5:1 and 1.25:1, are incorrect as they do not reflect the correct ratio and could result in incorrect dosing and potential side effects. It is important to follow the correct IV:PO ratio to ensure optimal treatment outcomes.
