General Medication Fact Sheet for Zyrtec

Field Information
Medication Name Zyrtec
Generic Name cetirizine hydrochloride
Purpose To temporarily relieve symptoms of hay fever (allergic rhinitis) or other upper respiratory allergies, such as runny nose, sneezing, and itchy, watery eyes. It is also used to relieve itching due to hives (urticaria).
Mechanism of Action Zyrtec is a second-generation antihistamine. It works by selectively blocking the histamine H1 receptors on cells, which prevents histamine (a chemical released during an allergic reaction) from causing allergy symptoms.
Available Strengths 5 mg, 10 mg (Tablets); 1 mg/mL (Oral Solution)
Dosage Frequency Tablets, Orally Disintegrating Tablets, Liquid Gels, Oral Solution (Syrup)
Common Side Effects Drowsiness, tiredness, dizziness, dry mouth, sore throat.
Serious Side Effects Serious side effects are rare. A severe allergic reaction (hives, difficulty breathing, swelling of the face, lips, tongue, or throat) or a very fast or pounding heartbeat require immediate medical attention.
Drug Interactions Use with alcohol, sedatives, or other central nervous system depressants can increase the effect of drowsiness.
Important Notes Zyrtec is available over-the-counter. While it is less likely to cause drowsiness than older antihistamines, it can still cause sleepiness in some individuals. Do not drive or operate heavy machinery until you know how this medication affects you.
Storage Store at room temperature (68°F to 77°F or 20°C to 25°C), away from moisture and high heat.
Missed Dose If you miss a dose, take it as soon as you remember. If it is almost time for your next dose, skip the missed dose and resume your regular schedule. Do not take two doses at once.
