RHINUCET Tablet is a combination pharmaceutical product designed for the treatment and symptomatic relief of upper respiratory conditions such as allergic rhinitis, sinusitis, common cold, and nasal congestion. The formulation generally comprises two active components: Cetirizine Hydrochloride, a second-generation antihistamine, and Pseudoephedrine Hydrochloride, a nasal decongestant. Together, these ingredients deliver a synergistic therapeutic effect, providing rapid and long-lasting relief from nasal allergy symptoms and congestion.

Cetirizine in RHINUCET works by blocking histamine H1 receptors in the body. Histamine is a chemical naturally released during allergic reactions, and its action leads to symptoms such as sneezing, itching, runny nose, and watery eyes. By inhibiting histamine, Cetirizine reduces inflammation and allergic response, offering effective control over hay fever and seasonal or perennial allergic rhinitis. As a second-generation antihistamine, it causes significantly less sedation compared to older antihistamines, allowing users to go about daily activities without drowsiness.

Pseudoephedrine is a sympathomimetic agent that functions as a vasoconstrictor. It shrinks the swollen blood vessels in the nasal passages, thus relieving nasal stuffiness and promoting easier breathing. It acts on alpha-adrenergic receptors, which causes the narrowing of nasal blood vessels and reduces mucosal edema. This is particularly beneficial during cold, flu, sinus infections, or allergies when nasal congestion is a prominent and uncomfortable symptom.

The combination of Cetirizine and Pseudoephedrine in RHINUCET Tablet makes it a dual-action therapy, where Cetirizine tackles the root cause of allergic symptoms and Pseudoephedrine deals with nasal blockage and pressure. This makes the tablet highly effective in treating conditions such as allergic rhinitis, sinus congestion, upper respiratory tract infections, and cold-related symptoms.

RHINUCET is usually taken orally, with or without food, and provides long-lasting relief—typically up to 12 to 24 hours depending on the formulation and dosing frequency. The onset of action is rapid, making it suitable for those who need fast symptom control during peak allergy seasons or acute cold episodes. It enhances respiratory comfort, reduces dependency on nasal sprays, and helps improve sleep quality in patients suffering from nighttime nasal congestion.

The tablet is generally well tolerated, but like all medications, it may have side effects. Common side effects include mild headache, dry mouth, dizziness, restlessness, or mild gastrointestinal discomfort. Pseudoephedrine may cause insomnia or increased heart rate in sensitive individuals, and caution should be exercised when used in patients with high blood pressure, heart conditions, hyperthyroidism, or glaucoma. Cetirizine, though typically non-sedating, may cause drowsiness in some individuals, especially at higher doses or in combination with other sedatives.

RHINUCET should be used with caution in children, elderly patients, pregnant or lactating women, and those with chronic illnesses. The use of alcohol or other central nervous system depressants should be avoided during treatment due to the potential risk of increased drowsiness. Patients are advised not to exceed the recommended dosage, and to seek medical advice if symptoms persist beyond a few days or worsen.

The product is manufactured under stringent quality standards in GMP-certified facilities. RHINUCET Tablets are packaged in moisture-resistant, tamper-proof packaging to ensure stability, safety, and efficacy throughout their shelf life. Each batch undergoes rigorous testing to confirm pharmacological accuracy and patient safety compliance.
