Laryxin Strawberry (Chlorhexidine Dihydrochloride, Lidocaine Hydrochloride Monohydrate)

Laryxin Strawberry combines chlorhexidine and lidocaine to provide antiseptic and analgesic effects for oral mucosal conditions.

• Oral mucosal lesions: reduces microbial load and eases pain, promoting healing.
• Sore throat: alleviates discomfort while limiting bacterial growth in the pharyngeal area.
• Mouth ulcers: provides local anaesthesia and antiseptic action to support ulcer resolution.
• Oral discomfort: offers temporary relief of pain associated with irritation or minor injuries.
• Dental procedures: provides topical anaesthesia and infection control for minor interventions.

• Chlorhexidine dihydrochloride exerts its antiseptic activity by binding to bacterial cell membranes, disrupting membrane integrity and precipitating intracellular contents, which leads to rapid microbial death. Lidocaine hydrochloride monohydrate blocks voltage‑gated sodium channels in peripheral nerve membranes, preventing depolarisation and thereby producing a reversible loss of sensation in the treated mucosal area. The combined formulation delivers simultaneous antimicrobial and local‑anaesthetic effects.

Laryxin Strawberry may cause local or systemic adverse reactions, which are generally mild but can be serious in rare cases.

Common Side Effects

• Mild burning or stinging sensation in the mouth that usually resolves within minutes.
• Transient alteration of taste perception lasting a short period after application.
• Temporary numbness of the treated area, which disappears as the effect wears off.
• Mild nausea if a small amount of the solution is inadvertently swallowed.

Serious or Rare Side Effects

• Allergic reactions such as angioedema, urticaria, or anaphylaxis requiring immediate medical attention.
• Severe mucosal ulceration or necrosis at the application site, indicating excessive exposure.
• Systemic lidocaine toxicity manifested by neurological signs (e.g., seizures) or cardiac arrhythmias.

When using Laryxin Strawberry, certain precautions should be observed to minimise risks and ensure optimal efficacy.

• Avoid use in individuals with known hypersensitivity to chlorhexidine, lidocaine, or any formulation components: discontinue immediately if reaction occurs.
• Do not exceed the recommended application frequency: follow prescriber instructions to prevent mucosal irritation.
• Keep the product away from eyes and nasal passages: avoid accidental contact.
• Use only for the intended oral mucosal areas: do not apply to large open wounds or damaged skin.
• Store at ambient temperature below 25 °C: keep in the original container, protect from moisture and direct sunlight.

Laryxin Strawberry may interact with other medicines or substances; awareness of these interactions helps avoid adverse effects.

Major Interactions (Avoid)

• Concurrent use with other topical anesthetics containing lidocaine: risk of cumulative systemic lidocaine toxicity.
• Co‑administration with strong oral antiseptics containing alcohol: may increase mucosal irritation.
• Use with drugs that prolong QT interval: lidocaine may exacerbate cardiac conduction effects.

Moderate Interactions (Monitor Closely)

• Systemic antibiotics that alter oral flora: may affect chlorhexidine efficacy.
• Anticoagulants (e.g., warfarin): chlorhexidine may rarely influence bleeding risk.
• Alcohol consumption: may enhance local irritation when combined with the product.
