What is the treatment for hexaconazole poisoning?

Treatment of Hexaconazole Poisoning

Hexaconazole poisoning should be managed with supportive care and symptomatic treatment, as there is no specific antidote available for this triazole fungicide. 1

Clinical Presentation

The primary manifestations of hexaconazole toxicity include:

• Central nervous system depression 1
• Generalized trembling 1

These symptoms were documented in a case report of a patient who ingested 500 mL of a hexaconazole-containing product (Hexastar 5.5% EC), who recovered completely with supportive measures alone 1.

Management Approach

Immediate Supportive Care

The cornerstone of treatment is general emergency care with symptomatic intensive-care measures as needed. 2 This approach is consistent with management of most poisonings where specific antidotes are unavailable 2.

Key supportive interventions include:

• Airway protection and respiratory support if CNS depression is significant 2
• Hemodynamic monitoring and support 2
• Management of tremors with benzodiazepines if severe 2
• Continuous monitoring of vital signs and neurological status 1, 2

Decontamination Considerations

Medical procedures intended to reduce poison absorption or enhance elimination are now only rarely indicated in modern toxicology practice. 2 The decision to pursue gastrointestinal decontamination should be made on a case-by-case basis, considering:

• Time since ingestion
• Amount ingested
• Patient's clinical status 2

Poison Control Center Consultation

Contact with a poison information center is strongly recommended to ensure efficient case management. 2 These centers provide:

• Real-time toxicological assessment 2
• Guidance on appropriate monitoring parameters 2
• Updates on any emerging treatment strategies 2

Important Caveats

• No specific antidote exists for hexaconazole poisoning, unlike certain other poisonings where antidotes such as atropine, naloxone, or 4-dimethylaminophenol are available 2
• Randomized clinical trials for hexaconazole poisoning treatment do not exist, so management is based on case reports and general toxicology principles 1, 2
• Complete recovery is expected with appropriate supportive care, as demonstrated in the published case report 1

Monitoring and Prognosis

Patients typically recover without sequelae when provided with adequate supportive therapy. 1 The duration of monitoring should be guided by:

• Resolution of CNS depression 1
• Cessation of trembling 1
• Normalization of vital signs 2
