Morrisons Dual Action Antiseptic Throat Honey & Lemon Flavour (Hexylresorcinol)

Hexylresorcinol is used as an antiseptic for conditions affecting the oral cavity and throat.

• Sore throat: reduces discomfort and microbial load in the throat.
• Mouth and throat antiseptic: provides broad‑spectrum antimicrobial activity in the oral cavity.
• Throat irritation: alleviates irritation associated with minor infections.

• Hexylresorcinol exerts its antiseptic activity by disrupting microbial cell membranes, leading to loss of membrane integrity and inhibition of bacterial growth. The compound interferes with enzyme systems essential for microbial metabolism, resulting in rapid reduction of viable organisms on the mucosal surfaces of the mouth and throat.

Hexylresorcinol lozenges are generally well tolerated, but some users may experience mild adverse reactions.

Common Side Effects

• Altered taste sensation: temporary metallic or sweet taste.
• Mild nausea: occasional stomach upset after ingestion.
• Oral irritation: transient burning or tingling in the mouth.
• Headache: mild, short‑lasting headache.
• Dizziness: light‑headed feeling in sensitive individuals.
• Discoloration of lozenge: harmless change in colour during dissolution.

Serious or Rare Side Effects

• Allergic reaction: rash, itching, swelling, or anaphylaxis.
• Severe oral ulceration: persistent sores in the mouth.
• Angioedema: rapid swelling of lips, tongue or face.
• Stevens‑Johnson syndrome: rare severe skin reaction.
• Respiratory distress: difficulty breathing in hypersensitive patients.
• Persistent vomiting: prolonged nausea and vomiting requiring medical attention.
