Cosome-E 120ml Syrup for Cough, Bronchitis & Asthma

Drug Class: Combination Respiratory — Antihistamine + Bronchodilator + Expectorant | Form: Oral Syrup | Prescription Status: Prescription Only (Rx) — DRAP Registered

What is Cosome-E Syrup 120ml?

Cosome-E Syrup 120ml is a combination prescription respiratory medicine used to treat both productive coughs (کھانسی جس میں بلغم ہو) and unproductive dry coughs (خشک کھانسی) associated with conditions including bronchitis, asthma, and smoker's cough. It combines three types of respiratory medicines in a single syrup — an antihistamine to reduce airway inflammation and dry irritated secretions, a bronchodilator to relax and widen the narrowed airways, and an expectorant to loosen and thin thick mucus so it can be coughed up and cleared more easily. Most respiratory conditions involve a combination of these problems simultaneously — airways that are inflamed, narrowed, and blocked with thick secretions — making a triple-combination preparation more effective than any single medicine used alone. Cosome-E addresses all three components of respiratory distress together, providing faster and more comprehensive relief from coughing, wheezing, chest tightness, and breathing difficulty. It must only be used as prescribed by your doctor and must be used with particular caution in children, elderly patients, and those with heart conditions or prostate problems due to the effects of the antihistamine and bronchodilator components.

What is Cosome-E Syrup Used For?

Cosome-E Syrup 120ml is approved for the management of the following conditions:

• Acute and Chronic Bronchitis — inflammation of the bronchial tubes causing persistent cough with or without mucus production, wheezing, and breathing difficulty (برونکائٹس — سانس کی نالیوں کی سوزش)
• Bronchial Asthma — reversible airway narrowing causing episodic wheezing, chest tightness, shortness of breath, and cough — particularly as an adjunct to primary asthma management (دمہ)
• Smoker's Cough — chronic cough with mucus accumulation caused by long-term cigarette or tobacco smoking irritating and damaging the airway lining
• Productive Cough with Thick Mucus — cough associated with heavy, thick, or sticky mucus secretions that are difficult to clear from the airways (بلغم والی کھانسی)
• Unproductive Dry Irritating Cough — persistent dry cough caused by airway irritation and hypersensitivity without significant mucus production (خشک، چڑچڑی کھانسی)
• Allergic Bronchospasm — airway narrowing and cough triggered by allergens including dust, pollen, animal dander, or chemical irritants
• Upper Respiratory Tract Infections with Bronchospasm — cough and airway tightness associated with viral or bacterial respiratory infections
• Chronic Obstructive Pulmonary Disease (COPD) — as supportive management for cough and mucus clearance in patients with COPD alongside primary disease management
• Tracheobronchitis — inflammation of the trachea and bronchi causing persistent cough, chest discomfort, and secretions

How Does Cosome-E Syrup Work?

Cosome-E Syrup combines three active medicines that target the multiple simultaneous components of respiratory distress through different but highly complementary mechanisms:

Antihistamine Component: The antihistamine in Cosome-E works by blocking H1 histamine receptors in the airways and respiratory mucosa. When the airways are exposed to allergens, infections, or irritants, the immune system releases histamine — a chemical mediator that triggers airway inflammation, causes swelling of the airway lining, stimulates mucus gland secretion, and contributes to the hypersensitivity that makes the airways more reactive and prone to spasm. By blocking histamine receptors, the antihistamine component reduces airway inflammation, dries excessive watery secretions, and dampens the hypersensitive airway response that causes persistent irritating cough. For unproductive dry coughs driven by airway irritation and histamine-mediated hypersensitivity, this is the most important component of the combination. The antihistamine also has a mild sedative effect that can help relieve the distress and restlessness associated with persistent coughing — particularly at night.

Bronchodilator Component: The bronchodilator in Cosome-E works by relaxing the smooth muscle that surrounds the bronchial tubes. In conditions like asthma, bronchitis, and allergic airway disease, these muscles go into spasm — squeezing the airways and narrowing the passage through which air must flow. This airway narrowing causes the characteristic wheeze, chest tightness, and sensation of breathlessness. The bronchodilator — typically a sympathomimetic or theophylline-related compound — stimulates receptors in the bronchial smooth muscle, causing the muscle fibres to relax and the airway diameter to widen. This bronchodilation allows significantly more air to flow with each breath, reduces the work of breathing, relieves wheezing and chest tightness, and creates a wider airway through which loosened secretions can be expelled more effectively when coughing. The bronchodilator effect usually begins within 30 to 60 minutes of taking the syrup and significantly improves breathing comfort.

Expectorant Component: The expectorant in Cosome-E — typically Guaifenesin or a similar mucolytic agent — works by stimulating the secretory cells lining the airways to increase the production of thinner, more watery respiratory secretions. It also reduces the stickiness and viscosity of existing thick mucus by breaking the chemical bonds within the mucus structure — making the mucus less thick, less adhesive, and much easier to move. This thinned, loosened mucus is then more easily propelled upward by the cilia — the tiny hair-like structures lining the airways — and can be cleared from the chest and throat by normal productive coughing. By facilitating mucus clearance, the expectorant relieves the sensation of chest congestion, reduces the effort required to cough productively, and helps prevent the build-up of stagnant secretions in the airways that can become infected and worsen bronchitis or pneumonia. Drinking plenty of water alongside the expectorant significantly enhances its effectiveness — adequate hydration is essential for thin, mobile secretions.

Dosage and Administration

⚠️ Take exactly as prescribed by your doctor. Do not exceed the prescribed dose. The antihistamine component causes drowsiness — do not drive, operate heavy machinery, or perform tasks requiring full concentration after taking this syrup. Drink plenty of water throughout the day to support the expectorant action. Always shake the bottle before use.

Important Instructions:

• Always shake the bottle well before every dose
• Use the measuring spoon or cup provided — never estimate with a household teaspoon
• Take after meals to reduce stomach discomfort from the bronchodilator component
• Drink a full glass of water with every dose — essential for expectorant effectiveness
• Continue drinking plenty of fluids throughout the day — at least 8 glasses of water daily — to keep airway secretions thin and mobile
• Do not take a double dose if you miss one — take the next dose at the scheduled time
• Do not use for more than 7 days without doctor review unless specifically directed
• If symptoms worsen or do not improve within 3 to 5 days, contact your doctor

Active Ingredients

Please check the product label or ask your pharmacist for the exact active ingredients and their specific strengths per 5ml in the Cosome-E Syrup pack dispensed to you — formulations may vary.

Who Should NOT Use Cosome-E Syrup?

Do not use this syrup if you or your child:

• Are allergic to any of the active ingredients — antihistamine, bronchodilator, expectorant, or any other listed ingredient in the formulation
• Have severe heart disease or a history of rapid or irregular heartbeat (دل کی تیز یا بے ترتیب دھڑکن) — the bronchodilator component can stimulate the heart and worsen arrhythmias
• Have uncontrolled high blood pressure (بلند فشارِ خون) — sympathomimetic bronchodilators can raise blood pressure
• Have hyperthyroidism (overactive thyroid — تھائرائیڈ کی زیادتی) — increased sensitivity to sympathomimetic bronchodilator effects
• Have narrow-angle glaucoma (آنکھ کے دباؤ کی بیماری) — antihistamines can raise intraocular pressure in susceptible patients
• Have urinary retention or enlarged prostate — antihistamines can worsen urinary difficulties by reducing bladder muscle tone
• Are taking Monoamine Oxidase Inhibitors (MAOIs) or have taken them within the last 14 days — serious and potentially dangerous interactions with both antihistamine and bronchodilator components
• Are under 2 years of age without specific medical prescription — combination respiratory syrups require careful medical supervision in very young children
• Are pregnant — particularly in the first trimester — consult your doctor before use

Tell your doctor before use if you have:

• Diabetes — bronchodilator components can affect blood sugar levels
• Liver disease — affects metabolism of multiple components in this syrup
• Kidney disease — affects clearance of active ingredients
• Epilepsy or seizure history — some bronchodilator compounds lower the seizure threshold
• Peptic ulcer or stomach problems — some components may irritate the stomach
• Difficulty urinating or any bladder problems — antihistamines worsen urinary retention
• If you are breastfeeding — antihistamine and bronchodilator components can pass into breast milk

Side Effects

Like all medicines, Cosome-E Syrup can cause side effects. Because it contains multiple active ingredients, side effects from each component are possible. Not everyone will experience them.

Common Side Effects (relatively frequent):

• Drowsiness and sedation — the most common side effect of the antihistamine component (نیند اور غنودگی) — do not drive or operate machinery after taking this syrup
• Dry mouth, dry throat, or dry nose — caused by the antihistamine's drying effect on secretions (منہ کی خشکی)
• Mild nausea or stomach discomfort — particularly with the bronchodilator component — taking with food reduces this significantly
• Mild headache — usually temporary
• Mild trembling or shakiness — associated with the bronchodilator component — usually mild and temporary
• Mild increase in heart rate (palpitations) — associated with sympathomimetic bronchodilators — usually settles with continued use
• Difficulty passing urine — antihistamine effect on bladder muscle — more noticeable in older male patients
• Mild dizziness — particularly when standing up quickly — antihistamine-related

Serious Side Effects (less common — seek medical help immediately):

• Rapid, pounding, or irregular heartbeat — the bronchodilator component can cause significant cardiac stimulation — stop the syrup and seek urgent medical attention if heartbeat becomes fast, irregular, or uncomfortable (دل کی تیز یا بے ترتیب دھڑکن)
• Significant rise in blood pressure — headache, visual disturbance, facial flushing — associated with sympathomimetic bronchodilators in susceptible patients
• Acute urinary retention — inability to pass urine at all — antihistamine-induced bladder muscle paralysis — particularly in elderly men with enlarged prostates — seek medical help immediately
• Seizures or convulsions — very rare — associated with excessive bronchodilator blood levels — seek emergency help immediately
• Severe allergic reaction — sudden widespread rash, swelling of face, lips or throat, difficulty breathing — seek emergency help immediately
• Worsening of breathing — paradoxical bronchospasm — if breathing difficulty worsens after taking the syrup rather than improving — stop immediately and seek urgent medical help
• Extreme drowsiness or unresponsiveness — particularly in children — antihistamine toxicity — seek emergency help immediately
• Severe agitation or restlessness in children — paradoxical excitement reaction to antihistamine — more common in young children — inform your doctor

If you notice any serious side effects, stop the syrup immediately and go to the nearest hospital or doctor.

Frequently Asked Questions

What is Cosome-E Syrup used for?

Cosome-E Syrup is used to treat both productive and dry coughs associated with bronchitis, asthma, smoker's cough, and allergic airway conditions. Its three-component formula addresses the full range of respiratory symptoms simultaneously — the antihistamine reduces airway inflammation and dry irritating cough, the bronchodilator widens narrowed airways to relieve wheezing and breathlessness, and the expectorant loosens thick mucus to make productive coughing easier and more effective.

Will Cosome-E Syrup make me drowsy?

Yes — drowsiness is a common and expected effect of the antihistamine component in Cosome-E Syrup. Do not drive a car, ride a motorcycle, operate heavy machinery, or perform any task that requires full alertness and concentration after taking this syrup. This drowsiness effect is more pronounced with the first few doses and may reduce slightly with continued use. Taking the syrup at night can be particularly helpful — it relieves cough while also allowing more restful sleep. Alcohol must be completely avoided as it significantly worsens this sedative effect.

Why must I drink plenty of water when taking Cosome-E Syrup?

The expectorant component in Cosome-E works by thinning and loosening the thick mucus in your airways so it can be coughed up and cleared. This thinning process depends heavily on adequate body hydration — if you are not drinking enough water, the mucus remains thick and sticky even with the expectorant. Drink at least 8 full glasses of water or clear fluids throughout the day while taking this syrup. Adequate hydration is essential for the expectorant to work effectively and for faster clearance of chest congestion.

Can I use Cosome-E Syrup alongside my asthma inhaler?

Only under your doctor's specific guidance. Cosome-E contains a bronchodilator that acts on the same airways as your inhaler — using both simultaneously can cause excessive bronchodilator effect, leading to rapid heartbeat, trembling, and raised blood pressure. Your doctor will advise on whether Cosome-E is appropriate alongside your existing asthma medicines and will adjust doses to prevent over-treatment. Never add Cosome-E to your asthma management without informing your treating doctor.

Is Cosome-E Syrup safe for elderly patients?

Cosome-E Syrup must be used with extra care in elderly patients. Older adults are significantly more sensitive to the antihistamine component — experiencing greater drowsiness, dizziness, confusion, and urinary retention than younger adults at the same dose. They are also more sensitive to the heart-stimulating effects of the bronchodilator component. Elderly patients should always start at the lowest effective dose as directed by their doctor and be monitored carefully for cardiac effects, urinary difficulties, and excessive sedation throughout treatment.

How long can I take Cosome-E Syrup before seeing a doctor again?

Do not use Cosome-E Syrup for more than 7 days without medical review. If your cough or breathing difficulty is not improving within 3 to 5 days of correct use, contact your doctor for reassessment — the underlying condition may require additional treatment such as antibiotics for bacterial bronchitis, inhaled steroids for asthma, or investigation for other causes of persistent cough. Never continue combination respiratory syrups indefinitely without regular medical supervision.
