# CHLORPHENIRAMINE 1 MG + PHENYLEPHRINE 2.5 MG ## Short Description **Chlorpheniramine 1 mg + Phenylephrine 2.5 mg** is a combination medicine containing an **antihistamine** and a **nasal decongestant**. It is commonly used for temporary relief of symptoms associated with **colds, allergies, and upper respiratory congestion**. * **Chlorpheniramine** helps relieve allergy symptoms such as sneezing, runny nose, and watery or itchy eyes. * **Phenylephrine** helps reduce nasal congestion by narrowing swollen blood vessels in the nasal passages. > **Important:** This combination is commonly found in pediatric or liquid formulations, but the appropriate dose depends heavily on the patient's **age, weight, formulation, and product label**. Do not use an adult cold medicine in young children unless specifically directed by a healthcare professional. ## Key Benefits * Helps relieve **runny nose**. * Reduces **sneezing** associated with allergies and colds. * Helps relieve **itchy or watery eyes** caused by allergies. * Provides temporary relief from **nasal congestion**. * Helps reduce swelling of the nasal passages. * Combines antihistamine and decongestant effects in one medicine. * May provide symptomatic relief during common colds and allergic rhinitis. ## Uses / Indications Chlorpheniramine + phenylephrine may be used for temporary relief of: * **Common cold symptoms**. * **Allergic rhinitis** (hay fever). * Runny nose. * Sneezing. * Nasal congestion. * Sinus/nasal stuffiness associated with colds or allergies. * Watery or itchy eyes associated with allergies. ### Important This medicine **relieves symptoms but does not cure the underlying viral infection** causing a common cold. It should not be used simply because a person has a cough, fever, or congestion without considering the underlying cause. ## How It Works ### Chlorpheniramine 1 mg Chlorpheniramine is a **first-generation H1 antihistamine**. It blocks histamine at H1 receptors, reducing allergy symptoms such as: * Sneezing. * Runny nose. * Watery eyes. * Nasal itching. Because chlorpheniramine can enter the brain, it may also cause **drowsiness**. ### Phenylephrine 2.5 mg Phenylephrine is a **sympathomimetic nasal decongestant**. It stimulates alpha-adrenergic receptors, causing blood vessels in the nasal passages to constrict. This reduces swelling of the nasal lining and helps improve airflow. ### Combined Action **Chlorpheniramine → reduces allergy symptoms** **Phenylephrine → reduces nasal congestion** ## Dosage & Administration The correct dose depends on: * Age. * Body weight. * Formulation. * Severity of symptoms. * Other medicines being taken. For this reason, **do not determine the dose from the ingredient strengths alone**, particularly for children. ### General Administration Instructions * Use exactly according to the product label or healthcare professional's instructions. * Measure liquid formulations with the supplied measuring device rather than a household spoon. * Do not exceed the recommended dose. * Do not use multiple cold/allergy medicines containing **chlorpheniramine or phenylephrine** at the same time. * Use for the shortest period necessary to control symptoms. ### Children Extra caution is required with children. Many combination cough-and-cold medicines are **not recommended for young children**, and age restrictions vary by country and product. For infants and young children, consult a healthcare professional before use. ### If You Miss a Dose For scheduled dosing, take the missed dose when remembered unless it is close to the next dose. **Do not double the dose.** ## Side Effects Possible side effects include: ### Chlorpheniramine-Related * Drowsiness. * Sleepiness. * Dizziness. * Dry mouth. * Dry throat. * Blurred vision. * Constipation. * Difficulty urinating. * Thickened respiratory secretions. ### Phenylephrine-Related * Nervousness. * Restlessness. * Headache. * Tremor. * Increased blood pressure. * Fast or pounding heartbeat. * Difficulty sleeping.
