4.9 Overdose


Oroeze/Benzydamine 0.15% w/v Mouthwash is unlikely to cause adverse systemic effects, even if accidental ingestion should occur. Intoxication is only expected in case of accidental ingestion of large quantities of benzydamine (> 300 mg) Intoxication is only to be expected if large quantities of Oroeze/Benzydamine 0.15% w/v Mouthwash are swallowed.

Symptoms associated with ingested overdose of benzydamine are mainly gastrointestinal symptoms and symptoms of the central nervous system. Most frequent gastrointestinal symptoms are nausea, vomiting, abdominal pain and oesophageal irritation. Symptoms of the central nervous system include dizziness, hallucinations, agitation, anxiety and irritability.


In acute overdose only symptomatic treatment is possible. Patients should be kept under close observation and supportive treatment should be given. Adequate hydration must be maintained.

5. Pharmacological properties
5.1 Pharmacodynamic properties

ATC code: A01A D02

Pharmacotherapeutic group: Other agents for local oral treatment

Benzydamine exerts an anti-inflammatory and analgesic action by stabilising the cellular membrane and inhibiting prostaglandin synthesis.

5.2 Pharmacokinetic properties


Oral doses of benzydamine are well absorbed and plasma drug concentrations reach a peak fairly rapidly and then decline with a half-life of about 13 hours. Less than 20% of the drug is bound to plasma proteins.

Although local drug concentrations are relatively large, the systemic absorption of mouthwash-gargle doses of benzydamine is relatively low compared to oral doses. This low absorption should greatly diminish the potential for any systemic drug side-effects when benzydamine is administered by this route.


Benzydamine is metabolised primarily by oxidation, conjugation and dealkylation.
