Both Zyrtec and Claritin may make you drowsy or tired. For that reason, you shouldnât take these medications if you also take muscle relaxers, sleeping pills, or other drugs that cause drowsiness. Taking them at the same time that you take sedating drugs can make you extremely sleepy.
The ionic formula of sodium chloride is NaCl. I'm not sure what is meant by structural formula, but there is one chlorine for each sodium atom in the ionic compound.
Sodium chloride contains two elements, sodium and chlorine. There are many poisonous drugs that also contain sodium, such as sodium fluoroacetate (rat poison), sodium hydroxide (lye), and sodium hypochlorite (bleach). Fortunately, we are not in the habit of sprinkling our food with these poisons in order to provide our body with needed sodium.
