Oh Lordy..here goes...Fleet's come in glycerin, bisacodyl, saline, and
mineral oil.  The only caution I see mentioned, repeatedly is not to use in
children under 2.  I think that is because of the mechanics and volume, not
the substance.  The Fleet prep kits are not to be used in children under
12, again the mechanics etc. There are other cautions regarding repeated
use and hypernatremia, hypocalcemia,hyperphosphatemia, acidosis etc.  But
we aren't talking about repeated use here . Let's get out the common sense,
regarding where it is going and what it is doing.  Biscodyl is even rec for
postpartum use. Sincerely, Pat in SNJ----------
