Frequently asked questions about Cetirizine

Cetirizine is an over-the-counter medication used to relieve allergy symptoms, such as runny nose, sneezing, itchy/watery eyes, and itching of the nose or throat.

Millions of Americans suffer from allergies every year. Allergies happen when your immune system gets confused. In some cases, your body may mistake harmless substances - like tree pollen or dog fur - as dangerous invaders. In this case, it may trigger an immune response to fend off the mistaken threat, causing you to feel many of the symptoms that make allergies a pain.

Tired of itching your eyes, blowing your nose, and clearing your throat? Talk to your doctor about whether cetirizine may be right for you.

Cetirizine has been approved by the FDA to temporarily relieve the symptoms of hay fever (allergy to dust, pollen, or other particles in the air) and other allergies like dust mites, animal dander, and molds. These symptoms tend to include a runny or stuffy nose, sneezing, itchy/watery eyes, and itching of the nose or throat. Cetirizine is also used to treat the itching and redness of skin caused by hives.

Cetirizine is a non-sedating antihistamine. Antihistamines work by completely blocking the effects of a substance called histamine in your body.

Histamine is released by your body when it detects something harmful, such as an infection. This causes your blood vessels to expand and your skin to swell, which helps to protect the body. When people have allergies, the body mistakes harmless particles in the air - like animal hair, pollen, or dust - for a threat and releases histamine. This flood of histamine causes unpleasant symptoms like itching, sneezing, and a running nose. Blocking the release of histamine helps to relieve these symptoms.

Cetirizine is generally well-tolerated. The most common side effects are drowsiness, fatigue, dry mouth, and dizziness. Rare but serious side effects include severe allergic reactions, including anaphylaxis, itching, and hives. Seek medical attention right away if you experience any allergic reactions or unusual side effects.

Ask a doctor before use if you have liver or kidney disease, or if you are pregnant, breastfeeding, or plan to become pregnant. Be careful when driving a motor vehicle or operating machinery after taking Cetirizine. Consumption of alcohol or other downers may increase the likelihood of drowsiness when taking Cetirizine.

Most people will feel the effects of Cetirizine within the first hour of taking it and will experience at least 24 hours of relief with a single dose.

The suggested dose for patients 6 years of age and older is 10 mg per day. It should be taken orally once per day. It should be taken around the same time every day and can be consumed with or without food.

Follow the directions on the package label carefully and ask your doctor or pharmacist to explain any part you don’t understand.
