No: Less. Many people sniff this up strongly which means that much of it goes to the throat and is swallowed. Read the instructions. It should be aimed to the side and retained inside the nose. Many people also take an antihistamine. NOT BENADRYL. Allegra, Claratin, Zyrtec. Generics are the same with lower price.
