That Wood-E failed to disclose this ingredient, or to go through the proper approval process for it, is problematic. Most seriously, the drug may interact with nitrates found in some other prescription drugs and may lower blood pressure to dangerous levels, side effects consumers without a prescription may not be aware of.
(Unfortunately, Wood-E is not really a wooden version of Wall-E. The above unrelated picture is from here.)
