Hi Clark,
Thank you for your question! These two medications can be used together, but it's important to monitor blood pressure while taking them together. There is no way for me to know whether this combination is appropriate for a specific child. The child's doctor should be the best person to ask about whether it's the correct combination, because the doctor should know the most about the child's condition and other medications. If you are in a position where you don't trust the physician, you may want to consider finding a new physician that you can trust. I hope this helps!
Best of luck,
Casey
