Hummmm: As there is little information about what is going on with your son it is difficult to comment. Questions about active acute treatment are best directed at the treating physician - they can explain their rationale to you - better than somebody else trying to guess what their rationale is. If after discussing with your son's doc you still have questions then requesting a second opinion is an option
