Sinarest Paediatric 1/125/2.5mg Oral Drops 15ml

Sinarest Paediatric 1/125/2.5mg Oral Drops 15ml is a combination medicine designed to address multiple symptoms associated with upper respiratory infections, colds, flu, and allergic reactions. By targeting three distinct physiological pathways, it provides comprehensive symptomatic relief during the acute phase of illness, when fever, body aches, nasal congestion, and allergic irritation often coexist.

Paracetamol (Acetaminophen) acts as the central analgesic and antipyretic component. It inhibits prostaglandin synthesis in the central nervous system, which raises the body’s pain threshold and helps regulate the hypothalamic heat centre to reduce fever and associated discomfort.

Phenylephrine is a selective alpha-1 adrenergic receptor agonist that constricts blood vessels in the nasal passages. This vasoconstriction reduces swelling of nasal membranes and decreases mucus production, effectively relieving nasal congestion and improving airflow.

Chlorpheniramine Maleate is a first-generation antihistamine that blocks H1 receptors, counteracting histamine-mediated symptoms such as sneezing, runny nose, and itchy or watery eyes. This action also helps reduce post-nasal drip and throat irritation. Together, these ingredients work synergistically to reduce symptom severity, improve comfort, and support rest and recovery. Sinarest Paediatric 1/125/2.5mg Oral Drops 15ml is rapidly absorbed and intended for short-term use to manage the discomfort associated with viral infections and environmental allergens.

Common cold and flu Symptoms

Relief of nasal congestion, runny nose, sneezing, headache, body ache, sore throat, and fever associated with upper respiratory tract infections.

Allergic Rhinitis

Management of nasal and ocular symptoms caused by seasonal or perennial allergic rhinitis, including sneezing, nasal itching, and watery eyes.

Sinusitis

Symptomatic relief of nasal congestion and facial pressure associated with acute sinusitis.

Febrile Conditions

Reduction of mild to moderate fever accompanying upper respiratory infections.

• Triple-Action Relief: Provides a single-dose solution for pain, congestion, and allergic symptoms, reducing the need for multiple separate medications.

• Effective Fever Reduction: Rapidly addresses febrile episodes, helping to stabilise body temperature and improve general well-being.

• Improved Respiratory Airflow: The decongestant effect of Phenylephrine opens narrowed airways, making breathing significantly easier.

• Anti-Inflammatory Response: Effectively interrupts the histamine cycle that causes persistent sneezing and nasal dripping.

• Systemic Comfort: Targets the "achy" feeling associated with viral infections, allowing for more restorative rest.

Sinarest Paediatric 1/125/2.5mg Oral Drops 15ml may cause side effects, although not everyone will experience them. Most reactions are mild and temporary, but some can be more significant and require medical attention.

Common Side Effects

• These are usually mild and often improve as your body adjusts

• Drowsiness or dizziness

• Dry mouth or throat

• Nausea or stomach discomfort

• Headache

• Restlessness or difficulty sleeping

Uncommon Side Effects

• These may occur less often, but can still affect some patients

• Constipation or difficulty passing urine

• Loss of appetite

• Fatigue or weakness

• Mild increase in blood pressure or heart rate

• Temporary changes in liver function tests

Serious Side Effects (Require Immediate Medical Attention)

• Although rare, these reactions can be serious. Contact your doctor right away if you notice

• Allergic reaction with rash, itching, swelling of the face or throat, or difficulty breathing

• Signs of liver problems, such as yellowing of skin or eyes, dark urine, or severe abdominal pain

• Heart‑related issues such as chest pain, irregular or fast heartbeat, or very high blood pressure

• Severe drowsiness, confusion, or hallucinations

• Take Sinarest Paediatric 1/125/2.5mg Oral Drops 15ml exactly as prescribed by your doctor or as indicated on the prescription label.

• Do not exceed the recommended dose or dosing frequency. Overdosing on Paracetamol can cause serious liver injury.

• Avoid taking other medicines containing Paracetamol while using Sinarest Paediatric 1/125/2.5mg Oral Drops 15ml.

• Use only for short-term relief of symptoms such as fever, headache, nasal congestion, runny nose, or body aches.

• If symptoms persist beyond the recommended duration or worsen, contact your healthcare provider.

• Paracetamol acts centrally in the brain by inhibiting cyclooxygenase (COX) enzymes, thereby reducing the synthesis of prostaglandins. Prostaglandins are chemical mediators that amplify pain signals and elevate body temperature. By lowering prostaglandin levels, paracetamol reduces pain perception and resets the hypothalamic thermostat, effectively lowering fever. Unlike NSAIDs, it has minimal anti-inflammatory activity, making it primarily an analgesic and antipyretic.

• Chlorpheniramine is a first-generation antihistamine that competitively blocks histamine H1 receptors. Histamine is a key mediator in allergic reactions, responsible for symptoms such as sneezing, rhinorrhea, watery eyes, and itching. By preventing histamine from binding to its receptors, chlorpheniramine alleviates these allergy-related symptoms. Because it crosses the blood–brain barrier, it can also cause sedation, which is a common side effect.

• Phenylephrine is a sympathomimetic agent that acts as an α1-adrenergic receptor agonist. Its primary action is vasoconstriction of blood vessels in the nasal mucosa. This reduces swelling and mucus secretion, thereby relieving nasal congestion. Unlike pseudoephedrine, phenylephrine has lower oral bioavailability but is still widely used as a decongestant due to regulatory restrictions on pseudoephedrine.

• Together, these ingredients provide rapid relief from multiple symptoms, making Sinarest Paediatric 1/125/2.5mg Oral Drops 15ml effective for short-term management of colds, flu, and allergies.

• Do Not Exceed the Recommended Paracetamol Dose: Paracetamol is safe at recommended doses but may cause serious liver injury in overdose. Always check other medicines you are taking for Paracetamol content to avoid unintentional excess dosing.

• Short-Term Use Only: Sinarest Paediatric 1/125/2.5mg Oral Drops 15ml is intended for short-term symptomatic relief. If symptoms persist beyond the recommended period, consult your doctor to rule out an underlying condition requiring specific treatment.

• Use Caution in Elderly Patients: Older patients may be more sensitive to the sedative effects of Chlorpheniramine and the cardiovascular effects of Phenylephrine. Medical supervision is particularly important in this group.

• Avoid in Certain Pre-existing Conditions: Patients with uncontrolled hypertension, hyperthyroidism, closed-angle glaucoma, or prostatic hyperplasia should use this combination only under medical supervision due to the effects of Phenylephrine and Chlorpheniramine, respectively.

• Food (Generally Safe): Sinarest Paediatric 1/125/2.5mg Oral Drops 15ml may be taken with or without food. Taking it with food may reduce the risk of gastric discomfort.

• Alcohol (Avoid): Alcohol increases the risk of Paracetamol-induced hepatotoxicity and enhances the sedative effects of Chlorpheniramine. Alcohol should be avoided during treatment.

• Caffeine (Mild Interaction): Caffeine may partially counteract the sedative effects of Chlorpheniramine but does not affect the therapeutic activity of other components.

• Monoamine Oxidase Inhibitors or MAOIs (Severe): Concurrent use with MAOIs is contraindicated. Phenylephrine combined with MAOIs may cause a dangerous hypertensive crisis. A minimum 14-day washout period after stopping an MAOI is required before starting Sinarest Paediatric 1/125/2.5mg Oral Drops 15ml.

• Other Paracetamol-Containing Products (Severe): Simultaneous use of other medicines containing Paracetamol significantly increases the risk of exceeding the maximum daily dose and causing hepatotoxicity. Always check product labels carefully.

• Warfarin (Moderate): Regular or high-dose Paracetamol use may enhance the anticoagulant effect of warfarin. INR monitoring is recommended during concurrent use.

• Other Antihistamines or Sedatives (Moderate): Combined use with other sedating antihistamines, benzodiazepines, or CNS depressants may intensify drowsiness and impair cognitive function.

• Antihypertensive Medicines (Moderate): Phenylephrine may reduce the blood pressure-lowering effectiveness of antihypertensive agents. Patients on antihypertensive therapy should use this combination under medical supervision.

• Tricyclic Antidepressants or TCAs (Moderate): May enhance the cardiovascular and anticholinergic effects of both Chlorpheniramine and Phenylephrine, increasing the risk of palpitations, hypertension, and urinary retention.

• Hypertension or Cardiovascular Disease (High Risk): Phenylephrine causes vasoconstriction and may raise blood pressure. Patients with uncontrolled hypertension or significant cardiovascular disease should avoid this combination or use only under close medical supervision.

• Hepatic Impairment (High Risk): Paracetamol is metabolised in the liver. Pre-existing liver disease increases the risk of hepatotoxicity even at standard doses. Use with caution and at the lowest effective dose.

• Prostatic Hyperplasia or Urinary Retention (Moderate Risk): Chlorpheniramine's anticholinergic effects may worsen urinary retention in patients with benign prostatic hyperplasia. Use with caution in this group.

• Closed-Angle Glaucoma (Moderate Risk): Chlorpheniramine's anticholinergic properties and Phenylephrine's sympathomimetic action may increase intraocular pressure. This combination should be avoided in patients with closed-angle glaucoma.

• Hyperthyroidism (Moderate Risk): Phenylephrine may exacerbate cardiovascular symptoms in patients with uncontrolled hyperthyroidism. Medical assessment is required before use.

• Diabetes Mellitus (Mild Risk): Some formulations may contain excipients such as sucrose. Patients with diabetes should confirm the suitability of the specific formulation with their doctor or pharmacist.

If you miss a dose, take it as soon as you remember. If it is almost time for your next dose, skip the missed dose and continue with your regular schedule. Never take two doses at the same time. Since Sinarest Paediatric 1/125/2.5mg Oral Drops 15ml is typically used for short-term symptomatic relief, missing a dose may simply mean a temporary return of symptoms. If symptoms are difficult to manage, consult your healthcare provider.
