The health care provider will measure and monitor the patient's vital signs, including temperature, pulse, breathing rate, and blood pressure. Symptoms will be treated as appropriate. The patient may receive:

• Cleaning of exposed skin
• Washing and examination of eyes as necessary

Most symptoms are seen in patients who are allergic to pyrethrins. Piperonyl butoxide has a low toxicity.
