Levotuss (Levodropropizine)

Levodropropizine acts on the peripheral cough pathway to provide symptomatic relief of cough.

• Dry cough: reduces frequency and intensity of coughing episodes.
• Non‑productive cough: suppresses the cough reflex without affecting mucus clearance.
• Upper respiratory tract infection‑related cough: offers symptomatic relief of irritation‑driven cough.

• Levodropropizine exerts its antitussive effect by inhibiting the peripheral release of sensory neuropeptides such as substance P from airway afferent nerves, thereby lowering the sensitivity of cough receptors in the respiratory tract. The drug does not bind to opioid receptors and its action remains localized to the airway mucosa, providing cough suppression with minimal central sedation.

Levodropropizine is generally well tolerated, but adverse reactions can occur.

Common Side Effects

• Nausea: mild stomach upset reported by some users.
• Dizziness: transient light‑headedness.
• Headache: occasional mild headache.
• Gastrointestinal discomfort: mild abdominal pain or dyspepsia.
• Taste alteration: temporary change in taste perception.
• Somnolence: mild sleepiness.

Serious or Rare Side Effects

• Allergic reactions: rash, itching, or urticaria.
• Angioedema: swelling of face, lips, or tongue.
• Severe skin reactions: Stevens‑Johnson syndrome or toxic epidermal necrolysis.
• Hepatic enzyme elevation: signs of liver dysfunction.
• Anaphylaxis: rare life‑threatening hypersensitivity.
• Neutropenia: low white blood cell count.

When using Levotuss, consider the following precautions to ensure safe use.

• Age restrictions: use in children only under medical supervision and according to prescribed age limits.
• Hepatic impairment: dose adjustment may be required; monitor liver function.
• Concomitant CNS depressants: caution as additive sedation may occur.
• Known hypersensitivity: avoid if allergic to levodropropizine or excipients.
• Pregnancy and breastfeeding: safety not established; use only if benefit outweighs risk.
• Store at room temperature: keep in the original packaging, protect from moisture and direct sunlight.

Levodropropizine may interact with other medicines; be aware of the following.

Major Interactions (Avoid)

• Other antitussives (e.g., codeine, dextromethorphan): additive cough suppression and increased risk of sedation.
• Strong CYP3A4 inhibitors (if metabolized via this pathway): may raise levodropropizine plasma levels.

Moderate Interactions (Monitor Closely)

• Sedating antihistamines: may enhance drowsiness.
• Alcohol: can increase central nervous system effects.
• Bronchodilators: monitor for any change in cough relief efficacy.
• Certain antibiotics (e.g., macrolides): observe for possible pharmacokinetic changes.
