Humex

Humex is an over‑the‑counter oral medication that contains the active ingredient benzydamine hydrochloride, a non‑steroidal anti‑inflammatory drug (NSAID). It is marketed in the European Union for local relief of inflammation, pain and irritation of the mouth and throat. The product is supplied without a prescription and is intended for short‑term use to soothe sore throat, pharyngitis and oral mucosal discomfort and to improve comfort during minor infections.

Humex is indicated for the symptomatic relief of several common oral and pharyngeal conditions.

- Relief of sore throat associated with viral or mild bacterial infections. - Treatment of pharyngitis to reduce pain and inflammation. - Management of oral mucositis, especially in patients undergoing chemotherapy or radiotherapy. - Soothing of minor mouth irritations after dental procedures or trauma. - Alleviation of inflammatory lesions such as aphthous ulcers in the oral cavity.

Adverse reactions to Humex are generally mild and localized, but rare serious events can occur.

Common: - Transient burning or stinging sensation in the mouth or throat. - Altered taste perception or metallic taste. - Mild nausea or dyspepsia. - Localised irritation or erythema of the oral mucosa. - Headache. - Dry mouth.

Serious: - Allergic reactions such as urticaria, angioedema or anaphylaxis. - Severe skin rash or Stevens‑Johnson‑like reactions. - Bronchospasm or respiratory distress. - Hepatic dysfunction (elevated liver enzymes) reported rarely. - Persistent or worsening oral ulceration.

Before using Humex, consider the following safety measures.

- Do not use if you have a known hypersensitivity to benzydamine or any component of the product. - Limit use to the recommended short‑term period; prolonged application may increase risk of irritation. - Keep the product out of reach of children; accidental ingestion can cause adverse effects. - Consult a healthcare professional before use during pregnancy, breastfeeding, or if you have severe liver disease. - Avoid simultaneous use of other topical NSAIDs in the mouth or throat to reduce cumulative irritation. - Discontinue use and seek medical advice if symptoms persist beyond a few days or worsen.

Humex may interact with other medicines or substances; consider the following guidance.

Avoid: - Concurrent use of other topical NSAIDs in the oral cavity, which can increase local irritation. - Systemic NSAIDs taken at high doses, as combined anti‑inflammatory effects may raise the risk of gastrointestinal discomfort. - Anticoagulant therapy (e.g., warfarin) when using large amounts, due to a potential increase in bleeding risk.

Use with caution: - Alcohol consumption, which may exacerbate mucosal irritation. - Other oral rinses or sprays containing anesthetic agents, as additive effects on sensation may occur. - Antihistamines or corticosteroid mouthwashes, requiring monitoring for unexpected reactions.
