Lidofon Limão (Chlorhexidine Dihydrochloride, Lidocaine Hydrochloride)

Lidofon Limão combines an antiseptic and a local anesthetic for conditions affecting the oral cavity.

• Oral mucositis: reduces microbial load and eases pain associated with mucosal inflammation.
• Post‑dental surgery care: helps prevent infection and lessens postoperative discomfort.
• Aphthous ulcers: provides analgesia and supports healing of painful mouth sores.

• Chlorhexidine Dihydrochloride disrupts bacterial cell membranes, leading to loss of membrane integrity and cell death, thereby providing broad‑spectrum antiseptic activity. Lidocaine Hydrochloride blocks voltage‑gated sodium channels in peripheral nerves, inhibiting nerve impulse propagation and producing localized anesthesia in the buccal mucosa.

Adverse reactions may occur with buccal use of Lidofon Limão.

Common Side Effects

• Altered taste sensation: temporary metallic or bitter taste.
• Mild burning or stinging: brief irritation at the application site.
• Transient numbness: localized loss of sensation lasting a few hours.
• Oral irritation: redness or mild inflammation of the mucosa.
• Dry mouth: reduced salivation during use.
• Minor swelling: slight edema of the gums or lips.

Serious or Rare Side Effects

• Allergic reaction: rash, itching, or swelling of the face, lips, or tongue.
• Anaphylaxis: severe, rapid onset of breathing difficulty, hypotension, or loss of consciousness.
• Stevens‑Johnson syndrome or toxic epidermal necrolysis: widespread skin blistering and mucosal involvement.
• Severe mucosal ulceration: extensive ulcer formation beyond expected healing time.

Before using Lidofon Limão, consider the following safety measures.

• Allergy assessment: avoid if known hypersensitivity to chlorhexidine or lidocaine.
• Pregnancy: use only when the potential benefit justifies the potential risk to the fetus.
• Oral mucosa integrity: do not apply to severely damaged or ulcerated tissue for prolonged periods.
• Concurrent local anesthetics: monitor for additive systemic toxicity if other anesthetics are used simultaneously.
• Pediatric use: safety and appropriate dosing have not been fully established; use under professional supervision.
• Store at ambient temperature: keep in the original container, protect from moisture and light.

Lidofon Limão may interact with other medicines or substances.

Major Interactions (Avoid)

• Other chlorhexidine‑containing products: cumulative irritation or mucosal toxicity.
• Systemic lidocaine therapy: increased plasma lidocaine levels may raise risk of systemic toxicity.

Moderate Interactions (Monitor Closely)

• Alcohol‑based mouthwashes: may enhance local irritation or burning sensation.
• Anticoagulants (e.g., warfarin): slight increase in bleeding tendency due to mucosal irritation.
• Antihistamines: may potentiate local anesthetic effect, leading to prolonged numbness.
