Allergies are hypersensitive responses from the immune system to substances which either enter or come into contact with the body.
Substances which usually cause an allergic reaction include:
- pet dander;
- certain plants;
- certain medications, like – penicillin or aspirin;
- certain foods, including shellfish or nuts;
- bee stings or bites from other insects.
An estimated 1 in 5 people in the United States suffers from some type of allergies, according to the Allergy and Asthma Foundation of America.
Common symptoms include:
- rashes are common and often itch;
- swelling may occur in larger areas under the skin (angioedema);
- hives, also referred to as urticaria – they are small, red, slightly elevated areas of swelling which often have a pale center;
- itchy skin;
- a runny nose;
- watery and itchy eyes.
Note – certain allergic reactions, called anaphylactic reactions, can be life-threatening.
Symptoms of anaphylaxis include – a sudden and severe drop in blood pressure, inability to breathe, and swelling of the airways.
The most effective treatment of an allergy is avoidance of the allergen.

Xyzal vs Benadryl – Which Is Better For Allergic Reactions?
Xyzal (levocetirizine) is an antihistamine medicine that is specifically indicated for the relief of symptoms associated with allergic rhinitis (seasonal and perennial) and chronic idiopathic urticaria in adults and children 6 years of age and older.
It belongs to a group of drugs called antihistamines. In addition, it is also called a non-sedating antihistamine as it doesn’t enter the brain in substantial amounts.
Benadryl (diphenhydramine) is a first-generation antihistamine drug which can be purchased without a prescription. It is indicated in treating symptoms of the cold and mild allergy, including sneezing, hives, a runny nose, and itching.
First generation antihistamines (like – diphenhydramine) are more sedating than the newer agents. Therefore, the actual difference between these two antihistamines is a less sedating effect on the central nervous system.
This makes Xyzal ideal for people who need to avoid sleepiness.
