Drug class: Antihistamines
What is Zyrtec?
Zyrtec (cetirizine) is an over-the-counter antihistamine used to relieve allergy symptoms, including sneezing, itching, watery eyes, and a runny nose, and also reduces hives (urticaria).
Zyrtec is usually taken once a day.
Zyrtec is available as tablets, capsules, chewable tablets, dissolving tablets and an oral syrup, in strengths of 2.5 mg, 5 mg and 10 mg. Which product is suitable depends on age.
Allergy symptoms are caused by your immune system releasing histamine when triggered by allergens, such as pollen, dust, or pet dander. Zyrtec works by blocking histamine H1 receptors, which prevents histamine from triggering allergy symptoms. Once Zyrtec blocks the H1 receptor, allergy symptoms improve.
How does Zyrtec work?
Zyrtec is a second-generation antihistamine that works by blocking H1 histamine receptors in your body (not your brain or spinal cord). This means this medicine is less likely to cause drowsiness compared with some older antihistamines. When your immune system releases histamine due to allergies, Zyrtec works by preventing histamine from attaching to the receptors and triggering allergy symptoms. By blocking histamine, Zyrtec reduces allergy symptoms.
Before taking this medicine
You should not use Zyrtec if you are allergic to cetirizine or similar medicines such as levocetirizine or hydroxyzine.
Do not use Zyrtec to prevent hives from any known cause, such as foods, insect stings, medicines, or latex or rubber gloves. This medicine will not prevent hives or an allergic skin reaction from occurring.
Ask a doctor or pharmacist before using Zyrtec if you have any health problems.
To make sure this medicine is safe for you, tell your doctor if you have ever had:
- recently used alcohol, sedatives, or tranquilizers; or
- liver or kidney disease.
- hives that are an unusual color, look bruised or blistered, or do not itch.
Tell your doctor if you are pregnant. You should not use Zyrtec if you are breastfeeding.
Zyrtec side effects
Get emergency medical help if you have signs of an allergic reaction to Zyrtec: hives, difficult breathing, swelling of your face, lips, tongue, or throat.
Common Zyrtec side effects may include:
- nausea, vomiting, diarrhea;
- cough, drowsiness, tiredness;
- headache, dizziness, feeling light-headed;
- feeling hot, sweating;
- numbness, tingling, burning pain;
- altered sense of taste;
- upset stomach, constipation; or
- nosebleed, dry mouth, sore throat.
This is not a complete list of side effects, and others may occur. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.

What cold medicine can you take with diabetes?
If you have diabetes and you catch a cold or flu, there are over-the-counter (OTC) medicines that are safe for you to take to help alleviate your symptoms. Check out our suggestions for pain and fever relievers, cough and congestion medications and more.
Remember to look for cold and flu medicines that are less likely to affect your blood sugar (glucose) levels, including sugar-free and alcohol-free options, or worsen any diabetes complications you may have.
Continue readingAllegra vs Zyrtec: What's the difference?
Allegra has the lowest risk of sedation out of all antihistamines so is preferred if an antihistamine is needed for people working in safety-critical jobs. Even though Zyrtec is 3.5 times more likely to cause sedation than Allegra, it is still much less sedating than some older antihistamines such as promethazine.
Continue readingCan you take Benadryl and Zyrtec together? Why it's not advised?
You should not take Benadryl and Zyrtec together unless directed by your doctor. Both are antihistamines, and combining them can increase risks for drowsiness, confusion, and other side effects.

According to the American College of Obstetricians and Gynecologists (ACOG), several over-the-counter (OTC) antihistamines may be taken during pregnancy.
