it is appropriate for his weight
HI, thanks for using healthcare magic
His doctor is suggesting that he receive 30 mg of prednisolone
per each dose (since he is suppose to get 2 tsp and one tsp is 15 mg).
In acute asthmatic attacks, prednisolone can be given as 1 to 2 tsp per kilogram of weight up to a maximum of 60 mg a day for older children and adults.
At his weight of 30 pounds which is approximately 13 to 14 kilograms, he can receive up to 26 to 28 mg of prednisolone per dose if his doctor used the upper limit of 2 tsp per kilogram.
The 26 or 28 mg would have been rounded up to 30 mg. This can be considered appropriate based on his weight.
This dose is not too much for his weight or age.
If he were to receive only 1 tsp , it would be just over the 1 tsp per kg (since he is 13 to 14 kg) because this would be only 15 mg. The doctor may not think that this dose may not be effective enough to treat his asthma.
If you are still concerned you can speak to your doctor about the dose. He may or may not consider 1 1/2 tsp per dose. It is possible that this may be effective but you should speak to his doctor first before altering the medication in the event that his recovery is affected.
I hope this helps and reassures you,feel free to ask any other questions
