What is the usual adult dosage of codeine administered orally?

10-20mg
20-40mg
30-60mg
40-80mg

The correct answer is: 30-60mg

Codeine is a commonly prescribed medication for pain and typically, the recommended adult dosage for oral administration ranges between 30-60mg. Option A (10-20mg) may not provide enough pain relief for the average adult, while option B (20-40mg) and D (40-80mg) may result in either reduced effectiveness or increased risk of side effects. It is important to follow the recommended dosage prescribed by a healthcare professional for safe and effective use of codeine.
