Nirolex Tosse E Catarro (Bromhexine Hydrochloride)

Bromhexine Hydrochloride is used as an expectorant to improve mucus clearance in various respiratory conditions.

• Cough with thick mucus: facilitates loosening and removal of viscous bronchial secretions.
• Bronchitis: aids expectoration, reducing cough duration and discomfort.
• Respiratory tract infections: supports clearance of mucus, helping alleviate congestion.

• Bromhexine Hydrochloride acts by depolymerizing mucopolysaccharide fibers in mucus, reducing its viscosity. The drug also stimulates ciliary activity in the respiratory epithelium, enhancing the transport of mucus toward the pharynx. This combined mucolytic and secretolytic action promotes more effective clearance of bronchial secretions, improving airway patency and easing cough. The effect is localized to the respiratory tract and does not significantly alter systemic mucus production.

Bromhexine Hydrochloride may cause a range of adverse reactions, most of which are mild and transient.

Common Side Effects

• Nausea: occasional upset stomach or feeling of queasiness.
• Vomiting: occasional expulsion of stomach contents.
• Diarrhea: loose stools that are usually self‑limiting.
• Abdominal pain: mild discomfort in the stomach area.
• Taste disturbance: altered or unpleasant taste sensation.
• Skin rash: mild erythematous eruption.

Serious or Rare Side Effects

• Allergic reactions: including urticaria, angioedema, or anaphylaxis.
• Severe skin reactions: such as Stevens‑Johnson syndrome or toxic epidermal necrolysis.
• Hepatic enzyme elevation: rare increases in liver function tests.
• Hemolysis: rare destruction of red blood cells.
• Eosinophilia: uncommon rise in eosinophil count.

When prescribing or dispensing Bromhexine Hydrochloride, consider the following precautions to ensure safe use.

• Pregnancy: consult a healthcare professional before use.
• Breastfeeding: use with caution; benefits should outweigh potential risks.
• Renal impairment: assess renal function and adjust dose if necessary.
• Asthma or chronic bronchospasm: monitor for possible bronchoconstriction.
• Drug interactions: review concomitant medications for potential interactions.
• Store at ambient temperature: keep in original packaging, protect from moisture and direct sunlight.

Bromhexine Hydrochloride can interact with other medicines; awareness of major and moderate interactions helps avoid reduced efficacy or increased toxicity.

Major Interactions (Avoid)

• Cough suppressants (e.g., codeine, dextromethorphan): may counteract the expectorant effect of bromhexine.
• Anticholinergic agents (e.g., ipratropium): may diminish mucociliary clearance enhanced by bromhexine.

Moderate Interactions (Monitor Closely)

• Macrolide antibiotics (e.g., erythromycin, clarithromycin): may increase bromhexine plasma levels.
• Bronchodilators (e.g., salbutamol): additive effect on airway clearance; monitor response.
• Antihistamines (e.g., diphenhydramine): may increase sedation when combined with other CNS depressants.
