For most medications, a pregnancy risk category is given to state whether the drug is safe for pregnant and nursing women to take. NR, or not rated, means that the information regarding this safety is inconclusive or has not been determined.
Benzphetamine is category X during pregnancy. Diethylpropion is category B. Other anorexiants have not been rated; however their use during pregnancy does not appear to be advisable. Safety for use of anorexiants has not been evaluated.

It has been proven safe in animal tests. Pregnancy category C- No safety tests have been performed, safety not known Pregnancy category D- Animal tests have shown fetal deformities, but no human tests have been done Pregnancy category X- Drug has been proven to cause birth defects in humans.
There is no such thing as a category 6 hurricane. The maximum is category 5. This category is open-ended, meaning that once a hurricane reaches category 5 strength (sustained winds of 156 mph or greater) it is classed as a category 5 no matter how much stronger the winds are. Also, hurricanes are not rated by size. They are rated by wind speed. A stronger hurricane is not necessarily bigger. Category 2 winds are 96-110 mph. Category 5 winds are 156+ mph.
Hurricanes and tornadoes are rated on different scales. Hurricanes are rated on the Saffir-Simpson scale from category 1 to category 5. Tornadoes are rated on the Enhanced Fujita scale (formerly the Fujita scale) from EF0 to EF5.
At peak strength Sandy was a category 2 hurricane but had weaken to category 1 strenth at landfall in the U.S.
