Honing & Citroen (Amylmetacresol, 2,4 Dichlorobenzyl Alcohol, Lidocaine Hydrochloride)

Honing & Citroen is indicated for the temporary relief of minor throat discomfort and irritation. It may be used when a mild antiseptic and analgesic effect is desired in the oral cavity.

• Relief of sore throat caused by viral upper‑respiratory infections
• Reduction of mouth and throat irritation from dryness or minor inflammation
• Adjunctive care for mild oral discomfort after dental procedures
• Supportive treatment for cough associated with throat irritation
• Symptomatic relief during seasonal allergies affecting the throat

• Amylmetacresol and 2,4‑dichlorobenzyl alcohol exert antiseptic activity by disrupting microbial cell membranes, leading to loss of cellular integrity and bacterial death. Lidocaine hydrochloride provides local anaesthesia by blocking voltage‑gated sodium channels in peripheral nerve endings, which reduces the transmission of pain signals from the oral mucosa.

Adverse reactions to Honing & Citroen are generally mild, but occasional more serious events have been reported.

Common

• Transient oral numbness or tingling
• Mild burning or stinging sensation in the mouth
• Unpleasant taste or after‑taste
• Temporary dry mouth
• Minor irritation of the oral mucosa

Serious

• Allergic reactions such as rash, itching, or swelling
• Severe mouth or throat swelling (angioedema)
• Difficulty breathing or swallowing
• Persistent numbness beyond the expected duration
• Signs of systemic toxicity (e.g., dizziness, confusion)

Before using Honing & Citroen, consider the following safety points.

• Do not use if you have a known allergy to any of the active ingredients.
• Avoid prolonged use; the product is intended for short‑term symptom relief only.
• Keep out of reach of children; accidental ingestion of large amounts may cause systemic effects.
• Consult a healthcare professional if symptoms persist for more than a few days.
• Use caution in individuals with pre‑existing oral lesions or ulcerations.
• Pregnant or breastfeeding persons should seek medical advice before use.

Honing & Citroen may interact with other substances that affect oral sensation or systemic absorption.

Avoid

• Concurrent use of other topical oral anesthetics, which may increase risk of excessive numbness.
• Ingestion of alcohol or strong mouthwashes immediately after use, as they can enhance irritation.

Use with caution

• Systemic medications that lower the seizure threshold, although rare, may be affected by lidocaine absorption.
• Antihistamines or other drugs that cause dry mouth, which could exacerbate irritation.
• Herbal supplements with known anticoagulant properties, if oral lesions are present.
• Any other OTC sore‑throat products containing similar antiseptic agents, to prevent additive exposure.
