Clinical monograph: ndiethyl3toulamide
Diethyl toluamide, commonly known as DEET, is an insect repellent used to provide protection against biting insects, including mosquitoes and ticks. It is widely used in various formulations for both personal and outdoor use, helping to prevent insect-borne diseases such as malaria and dengue fever.
Indications
- Insect repellent for personal use
- Protection against mosquito bites
- Protection against tick bites
Dosage
Children: For children, use DEET products according to the specific age-related guidelines on the label. Application should be done by an adult, and avoid use on infants under two months.
Adults: Apply evenly to exposed skin and clothing. Reapply as needed, particularly after swimming or sweating. Follow product-specific instructions for concentration and frequency.
Mechanism of action
DEET works by interfering with the insect's ability to detect human scent. It is believed to inhibit the function of olfactory receptors in insects, making it more difficult for them to locate humans. This repellent action is thought to be mediated through the modulation of odorant receptor neurons.
Pharmacodynamics
DEET is effective in repelling a variety of insects by masking human scent and altering their behavior. The duration of action can vary based on concentration, application method, and environmental conditions. Higher concentrations generally provide longer-lasting protection.
Pharmacokinetics
DEET is absorbed through the skin and can be detected in the bloodstream after application. Its metabolism occurs primarily in the liver, where it undergoes hydrolysis to yield metabolites. The excretion of DEET and its metabolites occurs mainly through urine, with a half-life of approximately 1-2 hours.
Pregnancy
The effects of diethyl toluamide (DEET) during pregnancy have not been well studied. It is recommended to use with caution and consult a healthcare provider.
Breast-feeding
DEET is excreted in human breast milk. Caution should be exercised when using while breastfeeding, and it is advisable to consult a healthcare provider.
Storage
Store at room temperature, away from moisture and heat. Keep out of reach of children.
