Citral is a mixture of two acyclic monoterpene alcohols, geraniol and neral. ## Overview Citral is primarily used as a fragrance ingredient and flavoring agent. It is not a registered pharmaceutical drug for systemic use in most regions. Its use is generally limited to topical applications in cosmetic or personal care products and as a food additive. ## Primary Indications * **Flavoring Agent:** In food and beverages. * **Fragrance Ingredient:** In perfumes, cosmetics, and household products. * **Topical Applications:** May be found in some over-the-counter (OTC) products for its scent or potential mild antimicrobial properties, though evidence for therapeutic efficacy is limited. ## Adult Dosing There is no standard adult dosing for citral as a pharmaceutical agent. Its concentration in consumer products varies widely. ## Pediatric Dosing There is no established pediatric dosing for citral as a pharmaceutical agent. ## Dose Adjustments Not applicable as it is not typically used as a systemic pharmaceutical. ## Contraindications * Known hypersensitivity to citral or its components (geraniol, neral). * May be contraindicated in certain cosmetic or personal care products for individuals with sensitive skin or known allergies. ## Adverse Effects * **Dermal Irritation/Sensitization:** Most common adverse effect, particularly with repeated topical exposure. May manifest as redness, itching, or rash. * Gastrointestinal upset if ingested in significant quantities (unlikely with intended use). ## Key Drug Interactions Not applicable for typical use as a flavoring or fragrance agent. No significant interactions are expected with pharmaceutical drugs. ## Monitoring Monitoring is generally not required for citral when used as a flavoring or fragrance ingredient. Discontinue use if skin irritation or allergic reaction occurs. ## Clinical Pearls * Citral is a common allergen in fragrances and can cause contact dermatitis. * It is used to impart a lemon-like scent and flavor. * Ensure patients are aware of its presence in consumer products if they have known fragrance sensitivities. **Disclaimer:** This information is for educational purposes only and does not constitute medical advice.
