Understanding Antihistamines: How They Work, Types & Uses
Histamines live in our body’s mast cells and play a crucial role in our inflammatory response. They are released when the body comes into contact with an allergen we are particularly sensitive to, boosting blood flow to the affected area of our body, such as the nasal passages.1 Antihistamines work to reverse this effect, but there are so many options available today it may be difficult to pick one. We’ll explore what antihistamines are, the symptoms they are intended to treat, and the most common antihistamines for allergies available.

There are also homeopathic alternatives to common OTC antihistamines, which are also available without a prescription because there are no harsh chemicals or harmful side effects and they can potentially provide the same results as other popular antihistamines without the drowsiness or jitteriness. These include Brillia Health’s products.

What Are Antihistamines?
Antihistamines are a class of drugs designed to treat common symptoms of allergies, such as coughing, sneezing, and watery eyes. They are typically used by people who have allergies to pollen, dander, and other allergens. According to the Cleveland Clinic, there are two major subtypes of antihistamines.2 The first subtype is called H-1 receptor antagonists or H-1 blockers, which is used to treat allergy symptoms. They work by physically blocking the H1 receptors and stopping the histamine from reaching its target, thus preventing your body's reaction to allergens.3 The second subtype is called H-2 receptor antagonists or H-2 blockers. These are used to treat gastrointestinal conditions.What Symptoms Do They Treat?
When your body overreacts to an allergen and releases too much histamine, a variety of undesirable symptoms can occur. Antihistamines are designed to reduce the following symptoms:- Runny nose and nasal congestion
- Itchy, watery, bloodshot eyes
- Cough
- Sneezing
- Itchy nose, roof of mouth, or throat
- Post-nasal drip
Common Types of Antihistamines
There are many antihistamines on the market today, available in capsules or in liquid form. Some of these antihistamines are available by prescription only, like the oral medication Clarinex, the nasal spray Astelin, and the eyedrops Optivar. Other antihistamines are available over the counter such as Sudafed and Zyrtec.Over-the-Counter Antihistamines
There are two generations of OTC antihistamines, with a number of undesirable side effects linked to many of them. The first generation of drugs was first approved by the FDA in the 1930’s and targeted histamine receptors in the brain and spinal cord by crossing the blood-brain barrier. Side effects linked to these drugs include drowsiness, dry mouth, dizziness, headaches, rapid heart rate, and constipation.4 Later allergy medications, such as Zyrtec and Sudafed, have been linked to such side effects as nausea, stomach pain, sore throat, and insomnia due to active chemical ingredients cetirizine and pseudoephedrine.51
