Morrisons Dual Action Antiseptic Throat Blackcurrant Flavour (Hexylresorcinol Bp)

Hexylresorcinol is used as a throat antiseptic to manage conditions affecting the oropharyngeal mucosa.

• Sore throat: reduces discomfort and lowers microbial load in the throat.
• Pharyngitis: provides symptomatic relief and antiseptic action during inflammation.
• Oral throat infection: helps control bacterial growth and supports healing.
• Tonsillitis: assists in reducing bacterial presence in the tonsillar area.
• Mouth ulcer: offers antiseptic protection and temporary pain relief.

• Hexylresorcinol exerts its antiseptic effect by disrupting microbial cell membranes, leading to loss of cellular integrity and death of bacteria and fungi. It also binds to sensory nerve endings in the mucosa, producing a local anaesthetic effect that temporarily reduces pain perception in the throat. The membrane disruption interferes with enzyme systems and nutrient transport, while the anaesthetic action is mediated through reversible blockade of sodium channels in peripheral nerves.

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

Common Side Effects

• Altered taste: temporary metallic or sweet taste in the mouth.
• Mild throat numbness: brief sensation of reduced feeling in the throat.
• Local irritation: slight burning or itching at the site of application.
• Dry mouth: temporary reduction in salivary flow.
• Nausea: occasional mild feeling of queasiness.

Serious or Rare Side Effects

• Allergic reaction: rash, itching, swelling, or hives.
• Angioedema: rapid swelling of the face, lips, or throat.
• Anaphylaxis: severe, life‑threatening allergic response requiring immediate medical attention.
• Severe throat edema: pronounced swelling that may impair breathing.

When using hexylresorcinol throat antiseptic, consider the following precautions to ensure safe use.

• Pregnancy: consult a healthcare professional before use.
• Breastfeeding: use with caution and under medical advice.
• Allergy: avoid if known hypersensitivity to hexylresorcinol or related compounds.
• Age restriction: not recommended for children under six years of age.
• Concurrent oral antiseptics: limit simultaneous use to reduce irritation risk.
• Store at ambient temperature: keep in the original packaging, protect from moisture and direct sunlight.

Hexylresorcinol can interact with certain substances; awareness of these interactions helps prevent adverse effects.

Major Interactions (Avoid)

• Alcohol: may increase local irritation and discomfort.
• Other topical anesthetics: additive numbness can lead to excessive loss of sensation.
• Anticoagulants: potential for increased mucosal bleeding when combined with strong irritants.

Moderate Interactions (Monitor Closely)

• Antihistamines: may mask early signs of an allergic reaction.
• Systemic antibiotics: no direct interaction but monitor for overlapping side effects.
• Smoking: can diminish antiseptic effectiveness and irritate the throat.
