# Citral ## Overview Citral is a mixture of two geometric isomers, geranial and neral, commonly found in the oils of many plants, such as lemon myrtle and lemongrass. It is primarily used in the flavor and fragrance industries and as an insect repellent. There is limited clinical data supporting its use as a therapeutic agent. ## Primary Indications * Flavor and fragrance additive. * Insect repellent. * Potential topical anti-fungal and anti-microbial properties are under investigation, but not established for clinical use. ## Adult Dosing There is no established, standardized adult dosing for therapeutic use due to lack of clinical trials. Dosing for topical applications (e.g., insect repellent) varies by product formulation and concentration; always follow product labeling. ## Pediatric Dosing There is no established pediatric dosing for therapeutic use. Safety and efficacy in children have not been determined. ## Dose Adjustments Not applicable as there is no established therapeutic dosing. ## Contraindications * Known hypersensitivity to citral or any component of a citral-containing product. * Potential for skin sensitization; use with caution in individuals with a history of allergic contact dermatitis. ## Adverse Effects * **Dermatologic:** Skin irritation, redness, itching, allergic contact dermatitis (especially with repeated or prolonged topical exposure). * **Gastrointestinal:** Nausea, vomiting (if ingested, though ingestion is not a recommended route of administration). * **Respiratory:** Bronchospasm (rare, primarily associated with inhaled essential oils containing citral). ## Key Drug Interactions There are no well-documented significant drug interactions for therapeutic use. However, concomitant use of other topical products that may cause skin irritation should be approached with caution. ## Monitoring * For topical applications: Monitor for signs of skin irritation or allergic reaction. * There is no routine laboratory monitoring due to lack of established therapeutic use. ## Clinical Pearls * Citral is primarily used as a flavoring agent and fragrance ingredient. Its therapeutic applications are largely unproven. * Topical use, particularly of concentrated essential oils containing citral, can lead to skin sensitization and allergic reactions. * If considering citral for any purpose, always consult product-specific information and healthcare professionals. *** **Disclaimer:** This information is intended for clinical use and is not a substitute for professional medical advice.
