Chlorpheniramine Maleate + Dextromethorphan + Phenylephrine is a triple-combination medication designed for the relief of common cold, cough, flu, and allergy symptoms. It contains Chlorpheniramine Maleate (an antihistamine), Dextromethorphan (a cough suppressant), and Phenylephrine (a nasal decongestant). This “Three-in-one” therapy helps relieve sneezing, runny nose, cough, nasal congestion, and throat irritation, improving comfort and quality of life.

Chlorpheniramine Maleate + Dextromethorphan + Phenylephrine is a fixed-dose combination medicine that targets multiple symptoms associated with upper respiratory tract infections and allergies. By combining three active ingredients, it provides fast and effective relief from cold, cough, and nasal congestion.

Chlorpheniramine Maleate, an antihistamine, works by blocking H1 receptors in the body. This action reduces the effects of histamine, a chemical responsible for allergic reactions, thereby alleviating symptoms such as sneezing, watery eyes, and itching. Controlling histamine-mediated responses helps calm the immune system and prevent further discomfort from allergic triggers.

Dextromethorphan acts as a cough suppressant, targeting the cough centre in the brain (medulla). It helps reduce dry, irritating coughs that often accompany colds and flu, without affecting normal respiratory function. Controlling the cough reflex provides relief from persistent coughing, allowing for better rest and daily functioning.

Phenylephrine is a decongestant that constricts blood vessels in the nasal passages, reducing swelling and mucus production. This helps relieve nasal congestion and sinus pressure, making breathing easier and improving overall comfort. By combining this with the antihistamine and cough suppressant, the syrup addresses multiple symptoms of upper respiratory illnesses in a single dose.

Overall, this combination syrup is suitable for short-term use to alleviate symptoms of cold, flu, and allergies. It is invaluable for individuals who need multi-symptom relief without taking multiple medications. Patients are advised to follow the recommended dosage and consult a healthcare provider if symptoms persist, to ensure safe and effective use.

Chlorpheniramine Maleate + Dextromethorphan + Phenylephrine is indicated for:

• Chlorpheniramine Maleate + Dextromethorphan + Phenylephrine is primarily used to provide relief from symptoms associated with the common cold, flu, and allergies. It helps reduce sneezing, runny nose, itchy or watery eyes, and throat irritation caused by histamine release.
• This combination also reduces dry, irritating cough and alleviates nasal congestion, making it easier to breathe. It is effective for short-term management of sinus pressure, blocked nose, and other upper respiratory discomforts.
• It offers multi-symptom relief in a single dose, improving comfort and daily functioning during colds, flu, or allergic episodes.

Multi-symptom relief in one tablet:

• It offers multiple benefits by targeting several cold, flu, and allergy symptoms in one dose. It helps relieve sneezing, runny nose, itchy eyes, and throat irritation, making daily activities more comfortable.
• The combination also suppresses dry cough and reduces nasal congestion, improving breathing and sleep quality. By addressing multiple symptoms simultaneously, it reduces the need for taking several different medications.
• It provides fast, convenient, and effective relief from common respiratory discomforts, helping patients recover more comfortably during colds.

Most side effects are mild and temporary.

Common side effects:

• Drowsiness or sleepiness
• Dry mouth, nose, or throat
• Dizziness
• Nausea or upset stomach

Less common side effects:

• Headache
• Nervousness or restlessness
• Blurred vision
• Constipation

Rare but serious side effects (seek medical attention immediately):

• Severe allergic reaction (rash, swelling of face, lips, or throat)
• Fast or irregular heartbeat
• Severe dizziness or confusion

• Dosage: Adults and children over 12 years can take 5–10 mL per dose, children 6–12 years take 5 mL, and children under 6 years should only take it if prescribed by a doctor.
• Timing: Take every 6–8 hours as needed, keeping doses evenly spaced, with a maximum of 4 doses in 24 hours with or without food.
• Swallowing: Shake the bottle well before use, measure the dose with a proper spoon or cup, and take it orally with or without food.
• Avoid Overuse: Do not exceed the recommended dose or frequency, as overuse can cause serious side effects like drowsiness, high blood pressure, or heart problems.
• Duration: Use the medicine short-term to relieve symptoms, usually for 3–7 days, and consult a doctor if symptoms persist or worsen.

Chlorpheniramine Maleate + Dextromethorphan + Phenylephrine works through three complementary mechanisms:

• Chlorpheniramine Maleate (Antihistamine): It blocks histamine H1 receptors in the body, reducing allergic symptoms such as sneezing, runny nose, itchy eyes, and throat irritation. This helps calm immune system reactions that cause cold and allergy symptoms.
• Dextromethorphan (Cough Suppressant): It acts on the cough center in the brain (medulla) to suppress the reflex that triggers coughing. This helps control dry, irritating cough without affecting normal lung function.
• Phenylephrine (Decongestant): It stimulates alpha-adrenergic receptors in the nasal blood vessels, causing vasoconstriction. This reduces swelling of nasal passages, decreases mucus production, and relieves nasal congestion.

Together, these three agents provide multi-symptom relief for colds, flu, and allergic conditions by targeting histamine-mediated reactions, cough reflex, and nasal congestion simultaneously.

• Take at night if drowsiness occurs
• Avoid alcohol while using this medicine
• Use for short-term relief only,see a doctor if symptoms persist
• Follow label instructions carefully to avoid overdose

Store at room temperature (below 30°C), away from moisture and light. Keep out of reach of children.

Drug–Food Interactions are generally minimal, but certain foods and beverages may affect its action.

• Alcohol should be kept away, as it can increase drowsiness caused by chlorpheniramine and may increase the sedative effect, making activities like unsafe driving.
• Caffeine containing drinks may reduce the effectiveness of phenylephrine, as caffeine can counteract its decongestant effect.
• Foods high in tyramine (like aged cheeses or processed meats) should be consumed cautiously, as phenylephrine is a sympathomimetic and could slightly raise blood pressure. Maintaining a balanced diet and adequate hydration helps optimize the medication’s effectiveness and reduces side effects.

• Sedatives, sleep medicines, or alcohol: Increased drowsiness
• MAO inhibitors: Risk of serious interactions
• Other cold or cough medicines: Risk of overdose due to duplicate ingredients

• High Blood Pressure or Heart Disease: Phenylephrine can raise blood pressure and increase heart rate, so use with caution in patients with hypertension, heart disease, or arrhythmias.
• Glaucoma: Chlorpheniramine may increase eye pressure, which can worsen glaucoma.
• Thyroid Disorders: Phenylephrine may aggravate hyperthyroidism by stimulating the cardiovascular system.
• Diabetes: Phenylephrine can affect blood sugar control, so diabetics should monitor glucose levels closely.
• Prostate Enlargement (BPH): Phenylephrine may worsen urinary retention in men with an enlarged prostate.
• Asthma or Respiratory Disorders: Chlorpheniramine can thicken respiratory secretions, and dextromethorphan may suppress necessary cough reflexes, so caution is advised.
• Seizure Disorders: Dextromethorphan may lower the seizure threshold in susceptible individuals.
• Patients with any of these conditions should consult a doctor before taking this syrup to ensure safe use and to discuss potential alternatives or dose adjustments.

Dosage depends on age and condition, generally for adults and children over 12 years is 10 ml orally, 3 times a day. For children 6–12 years, the dose is 5 ml orally, 3 times a day.Follow your doctor’s instructions strictly.

Overdose may cause extreme drowsiness, confusion, fast heartbeat, or breathing difficulty. Seek emergency medical help immediately.

Take the missed dose as soon as you remember. If it is almost time for your next dose, skip it. Do not take two doses at once.
