Humex Rhume (Chlorphenamine Maleate, Paracetamol | Pseudoephedrine Hydrochloride, Paracetamol)

Humex Rhume is indicated for the symptomatic treatment of common cold and flu‑related complaints.

• Relief of nasal congestion caused by swollen nasal passages.
• Reduction of fever and headache associated with viral upper‑respiratory infections.
• Alleviation of sore throat discomfort and general body aches.
• Temporary easing of sinus pressure and watery eyes.
• Decrease of mild ear pressure or fullness during a cold.
• Support for overall comfort while recovering from an upper‑respiratory viral illness.

• Chlorphenamine maleate acts as an H1‑receptor antagonist, blocking histamine‑mediated vasodilation and edema in the nasal mucosa. Paracetamol inhibits cyclo‑oxygenase enzymes, reducing prostaglandin synthesis to lower fever and relieve pain. Pseudoephedrine hydrochloride stimulates α‑adrenergic receptors on nasal blood vessels, producing vasoconstriction that decreases mucosal swelling and improves airway patency. The combined actions target the three major pathways involved in cold and flu symptomatology.

Adverse reactions to Humex Rhume are generally mild, but some individuals may experience more pronounced effects.

Common

• Drowsiness or mild sedation.
• Dry mouth or throat.
• Nausea or mild stomach upset.
• Slight increase in heart rate or palpitations.
• Headache or mild dizziness.
• Insomnia or difficulty sleeping.
• Blurred vision.
• Tremor or shakiness.
• Feeling of restlessness or agitation.
• Reduced appetite.
• Mild flushing of the skin.
• Slight difficulty concentrating.
• Temporary increase in urinary frequency.

Serious

• Severe allergic reaction such as rash, itching, swelling of face or throat.
• High blood pressure or cardiac arrhythmia.
• Persistent vomiting preventing oral intake.
• Seizures (rare).
• Severe liver injury (very rare).
• Chest pain or tightness.

When using Humex Rhume, certain precautions should be observed to minimise risk and ensure safe use.

• Do not exceed the recommended daily dose; overdose can increase risk of liver toxicity from paracetamol.
• Avoid use in individuals with known hypersensitivity to any of the ingredients.
• Use cautiously in patients with hypertension, heart disease, diabetes, thyroid disorders, or enlarged prostate.
• Pregnant or breastfeeding women should consult a healthcare professional before taking this product.
• Children under a specified age should not use this formulation unless directed by a physician.
• Concomitant use with other decongestants or stimulant drugs may raise blood pressure.
• Alcohol consumption may enhance drowsiness and liver strain.

Humex Rhume may interact with other medicines, and certain combinations should be avoided or used only with medical supervision.

Avoid

• Monoamine oxidase inhibitors (MAOIs) or other sympathomimetic agents, which can cause excessive hypertension.
• Other products containing paracetamol, to prevent cumulative dose exceeding safe limits.
• Strong CYP450 enzyme inducers that may reduce the effectiveness of chlorphenamine.

Use with caution

• Antihypertensive drugs, as pseudoephedrine may diminish their blood‑pressure‑lowering effect.
• Antidepressants, especially tricyclics or SSRIs, which can increase the risk of serotonin‑related side effects.
• Anticoagulants or antiplatelet agents, because paracetamol may affect bleeding risk.
• Antihistamines other than chlorphenamine, as additive sedation may occur.
