Antihistamines are classified as H1 blockers and H2 blockers, depending on the type of receptors (on the surface of cells) that they act on.
These are meant to treat many symptoms at the same time.
H1 receptors are associated with human tissue involving capillaries, and H2 receptors predominate in the lining of the stomach.
Even the best antihistamines do not offer anything in terms of permanent relief, nor do they relieve nasal congestion.
If you take a combination medicine, it’s important to know each active ingredient.
One or more could interact with other medicines you’re taking. Many OTC cold and allergy medicines contain them already. If you take more than 1 of these medicines, you may get much more antihistamine than is good for you.
Second-generation antihistamines are less likely to interact with other medicines you are taking.
