More questions... <wink>
- timing? does he get this medication in the morning, evening, split dose???
- what size were the increments... 1mg and then up by another 1mg?
Sometimes, you can "split" a dose... long-acting, not usually, but there may be half-step versions available. Or use long-acting, supplemented with short-acting... For lots of medications, 0.5mg is enough to make a difference.
