Following oral exposure, the treatment is symptomatic and supportive and includes monitoring for the development of hypersensitivity reactions with respiratory distress. Provide adequate airway management when needed. Gastric decontamination is usually not required unless the pyrethrin product is combined with a hydrocarbon. Following inhalation exposure, move patient to fresh air. monitor for respiratory distress. If cough or difficulty breathing develops, evaluate for respiratory tract irritation, bronchitis, or pneumonitis. Administer oxygen and assist ventilation as required. Treat bronchospasm with inhaled beta2 agonist and oral or parenteral corticosteroids. In case of eye exposure, irrigate exposed eyes with copious amounts of room temperature water for at least 15 minutes. If irritation, pain, swelling, lacrimation, or photophobia persist, the patient should be seen in a health care facility. If the contamination occurs through dermal exposure, Remove contaminated clothing and wash exposed area thoroughly with soap and water. A physician may need to examine the area if irritation or pain persists. Vitamin E topical application is highly effective in relieving parenthesis. (L363)

The major metabolic pathways are cleavage of ester linkage and oxidation at the acid and alcohol moieties. Ester hydrolysis leads to formation of anilino acid. The anilino acid is further conjugated with amino acids (glycine, serine, threonine, and valine), bile acids (cholic, taurochoric, and taurochenodeoxycholic), and glycerols (oleoyl- and linoleoylglycerol). In addition, an amide derivative of anilino acid was found. These conjugation reactions of anilino acid with bile acid (cholic acid, taurocholic acid, and taurochenodeoxycholic acid) and with glycerol and monoglycerides have rarely been reported as conjugates with xenobiotics. The major urinary metabolites are anilino acid, its hydroxymethyl derivative, its glycine conjugate, haloaniline, and sulfate conjugate of hydroxyhaloaniline. On the other hand, the major fecal metabolites are anilino acid, its amide derivative, and several conjugates of anilino acid with several endogenous components. An unexpected difference between fluvalinate and other pyrethroids is the minimal amt of hydroxylation at the 4'-position of the alcohol moiety. (T80)
