# CETIRIZINE 10 MG ## SHORT DESCRIPTION **Cetirizine 10 mg** is a second-generation **antihistamine** used to relieve symptoms of allergies such as sneezing, runny nose, itchy or watery eyes, and itching of the nose or throat. It is also commonly used to relieve **urticaria (hives)** and associated itching. Cetirizine works by blocking the effects of **histamine**, a substance released during allergic reactions. It generally causes less drowsiness than older antihistamines, although **sleepiness can still occur** in some people. --- ## KEY BENEFITS * Provides relief from **allergy symptoms**. * Helps reduce **sneezing and runny nose**. * Relieves **itchy or watery eyes** associated with allergies. * Helps relieve **nose and throat itching**. * Reduces **skin itching and hives (urticaria)**. * Usually provides approximately **24-hour symptom relief** with once-daily dosing in adults. * Generally causes less sedation than many first-generation antihistamines. --- ## USES / INDICATIONS Cetirizine 10 mg may be used for: ### Allergic Rhinitis It can relieve symptoms of: * Seasonal allergic rhinitis (hay fever) * Perennial allergic rhinitis * Sneezing * Runny or itchy nose * Itchy or watery eyes ### Urticaria Cetirizine may be used to relieve: * Hives * Skin itching * Redness associated with allergic skin reactions ### Other Allergic Conditions It may be recommended for certain other **histamine-mediated allergic symptoms** according to a healthcare professional's advice. > Cetirizine does not treat the underlying cause of an allergy and does not cure infections such as the common cold. --- ## HOW IT WORKS Cetirizine is a **selective H1 antihistamine**. During an allergic reaction, the body releases histamine, which binds to H1 receptors and contributes to symptoms such as: * Sneezing * Itching * Runny nose * Watery eyes * Skin hives Cetirizine blocks H1 histamine receptors, reducing the effects of histamine and therefore relieving allergic symptoms. Because cetirizine has relatively limited penetration into the brain compared with older antihistamines, it generally causes **less sedation**, although drowsiness remains possible. --- ## DOSAGE & ADMINISTRATION ### Adults and Adolescents 12 Years and Older The usual dose is: **10 mg once daily.** Some people with mild symptoms may obtain adequate relief with a lower dose. ### Children Dosing for children depends on **age, formulation, and medical advice**. Do not give the 10 mg adult-strength tablet to a young child unless specifically instructed by a healthcare professional. ### Older Adults Older adults may require dose consideration depending on kidney function and overall health. ### Kidney Impairment Patients with reduced kidney function may require a **lower dose or longer dosing interval**. ### Administration * May be taken **with or without food**. * Take with water. * Take at approximately the same time each day when used regularly. ### Missed Dose Take the missed dose when remembered unless it is nearly time for the next dose. **Do not take two doses at the same time.** --- ## SIDE EFFECTS ### Common Side Effects Possible side effects include: * Drowsiness or sleepiness * Fatigue * Headache * Dry mouth * Dizziness * Nausea * Sore throat Although cetirizine is considered less sedating than many older antihistamines, **some individuals can still become significantly drowsy**. ### Serious Side Effects Serious allergic reactions are uncommon but may include: * Swelling of the face, lips, tongue, or throat * Difficulty breathing * Severe skin reactions Seek immediate medical attention if these symptoms occur. --- ## PRECAUTIONS & WARNINGS * Cetirizine may cause **drowsiness**, particularly when first starting treatment. * Avoid driving or operating machinery until you know how cetirizine affects you. * Avoid or limit alcohol because it may increase sedation. * Tell your healthcare professional if you have **kidney disease**. * Older adults may be more susceptible to drowsiness or other adverse effects. * Tell your doctor if you have difficulty urinating or conditions that may cause urinary retention. * Do not exceed the recommended dose. * Consult a healthcare professional before giving cetirizine to young children. * If allergy symptoms persist or worsen despite treatment, seek medical advice. --- ## DRUG INTERACTIONS Cetirizine has relatively few clinically significant drug interactions, but certain substances can increase sedation. ### Alcohol Alcohol may increase **drowsiness and impaired alertness**. ### Sedatives and CNS Depressants Increased sedation may occur with: * Sleeping medicines * Sedative medicines * Opioid pain medicines * Certain anti-anxiety medicines * Other medicines that cause drowsiness ### Other Antihistamines Avoid taking multiple antihistamines together unless specifically recommended by a healthcare professional. ### Theophylline Some evidence indicates that theophylline may slightly reduce cetirizine clearance.
