Dextromethorphan contains not less than 98.0percent and not more than
101.0percent of C18H25NO,calculated on the anhydrous basis
the formula used in calculating molar mass is the molecular formula, the
formula weight computed is the molecular weight. The percentage by
weight of any atom or group of atoms in a compound can be computed by
dividing the total weight of the atom (or group of atoms) in the formula
by the formula weight and multiplying by 100.
Formula weights are especially useful in determining the relative
weights of reagents and products in a chemical reaction. These relative
weights computed from the chemical equation are sometimes called
equation weights.
In chemistry, the formula weight is a quantity computed by multiplying
the atomic weight (in atomic mass units) of each element in a chemical
formula by the number of atoms of that element present in the formula,
then adding all of these products together.
Dextromethorphan is used to temporarily relieve cough caused by the
common cold, the flu, or other conditions. Dextromethorphan will relieve
a cough but will not treat the cause of the cough or speed recovery.
Dextromethorphan is in a class of medications called antitussives. It
works by decreasing activity in the part of the brain that causes
coughing.
It is important for you to keep a written list of all of the
prescription and nonprescription (over-the-counter) medicines you are

dietary supplements. You should bring this list with you each time you
visit a doctor or if you are admitted to a hospital. It is also
important information to carry with you in case of emergencies.
