What is Antihistamine?

Antihistamines are medications used to treat allergies and hay fever. They work by blocking the body’s natural histamine response, which is responsible for many of the symptoms associated with allergies. One of the most common antihistamines is cetirizine, a drug that has been used safely for over 20 years to treat symptoms such as sneezing, itching, runny nose, watery eyes, and hives.

Cetirizine works by preventing histamine from binding to its receptors in the body. This reduces inflammation and swelling throughout the body, which helps relieve allergy symptoms. It can be taken orally or topically in a cream or ointment form to provide relief from skin irritations caused by allergies. Additionally, cetirizine can also be used to prevent certain types of allergic reactions, such as asthma attacks or anaphylactic shock.

What Are The Precautions To Be Taken When Taking Cetirizine?

Before taking cetirizine, it is important to know the precautions to be taken. These include:

  • be aware of your surroundings and avoid crowds or other situations where you might be exposed to allergens
  • avoid sun exposure while taking the drug, especially during peak allergy season (spring and fall)
  • take the medication with food if possible to avoid stomach upset.

Cetirizine should not be used to treat hives that are swollen or blistering, have an unusual color, or don’t itch. If you get these hives, contact your physician.

In the event that your hives do not subside during the first three days of treatment or if they persist for more than six weeks, stop using cetirizine and contact your physician. Call your doctor if you are unsure of what is causing your hives.

Get emergency medical treatment immediately away if you are using cetirizine to treat hives and experience any of the following symptoms: trouble breathing, swallowing, speaking, or tongue-swelling; wheezing; drooling; dizziness; or loss of consciousness. These could be signs of anaphylaxis, a potentially fatal allergic reaction. Your doctor might recommend an epinephrine injector if he thinks you might develop anaphylaxis along with your hives. Cetirizine should not be used in place of an epinephrine injector.
