Lidocain Halsschmerztabletten Engelhard (Lidocaine Hydrochloride Monohydrate)

Lidocaine Hydrochloride tablets act locally on the oropharyngeal mucosa to alleviate pain associated with inflammatory or irritative conditions.

• Sore throat: provides temporary numbing relief of pain and discomfort in the throat.
• Oral mucosal pain: reduces pain from lesions, abrasions, or inflammation of the oral lining.
• Minor throat irritation: eases discomfort caused by coughing, dryness, or minor injuries.
• Post‑viral throat discomfort: helps alleviate lingering soreness after viral upper respiratory infections.
• Oral ulcer pain: numbs the area around aphthous ulcers to lessen pain during eating or speaking.

• Lidocaine Hydrochloride exerts its effect by reversibly blocking voltage‑gated sodium channels in neuronal membranes. This inhibition prevents the initiation and propagation of action potentials, thereby halting nerve impulse transmission in the treated area. The localized reduction in sodium influx leads to loss of sensation, producing a rapid onset of topical anesthesia without significant systemic absorption when used as directed.

Lidocain Halsschmerztabletten Engelhard may cause adverse reactions, most of which are mild and transient.

Common Side Effects

• Mild oral irritation or burning sensation
• Transient numbness of the tongue or throat
• Altered taste perception
• Light‑headedness or mild headache
• Nausea

Serious or Rare Side Effects

• Allergic reactions such as rash, itching, or angioedema
• Severe throat swelling or difficulty breathing
• Cardiac arrhythmias, seizures, or methemoglobinemia (rare)
• Severe systemic toxicity (e.g., CNS depression)

When using Lidocain Halsschmerztabletten Engelhard, consider the following precautions to ensure safe and effective use.

• Allergy assessment: verify the patient has no known hypersensitivity to lidocaine or other amide‑type local anesthetics.
• Pediatric use: follow age‑appropriate dosing guidelines and avoid use in infants unless directed by a healthcare professional.
• Frequency limitation: do not exceed the recommended number of tablets per day to prevent systemic exposure.
• Systemic toxicity monitoring: watch for signs such as dizziness, tinnitus, or circumoral numbness, especially with prolonged use.
• Drug interactions: avoid concurrent use with other topical anesthetics or class I antiarrhythmics without medical supervision.
• Store at ambient temperature: keep below 25 °C in the original packaging, protected from moisture and direct sunlight.

Lidocain Halsschmerztabletten Engelhard can interact with other medicines; awareness of these interactions helps prevent adverse effects.

Major Interactions (Avoid)

• Concurrent use of other amide local anesthetics: increased risk of cumulative lidocaine toxicity.
• Class I antiarrhythmic agents (e.g., quinidine, procainamide): may potentiate cardiotoxic effects.
• Strong CYP3A4 inhibitors (e.g., ketoconazole): can raise systemic lidocaine levels.

Moderate Interactions (Monitor Closely)

• Alcohol consumption: may enhance central nervous system depression.
• CYP3A4 inducers (e.g., rifampin): may reduce lidocaine efficacy.
• High‑dose aspirin or NSAIDs: may increase risk of minor bleeding when mucosal irritation occurs.
