Thank you very much for the inquiry regarding the prophylaxis recommendation. The information came mainly from the two articles listed below. Although no formal recommendation by the CDC has been made, these are recommendations that “should be strongly considered” based on the findings in the paper by Nadelman et al. Also, the American Academy of Pediatrics’ Red Book states: “On the basis of a study of doxycycline for prevention of Lyme disease after a deer tick bite, some experts recommend a single 200-mg dose (4.4 mg/kg for body weight < 45 kg) of doxycycline for people 12 years of age (the lower limit of age studied) and older who have been bitten in an area with hyperendemic infection who have found an engorged deer tick, especially if the suspected duration of attachment is 72 hours or longer; gastrointestinal tract adverse effects occur commonly. Data are insufficient to recommend amoxicillin prophylaxis.” Readers should note this discrepancy: The “Index of Suspicion” case recommends prophylaxis if the attachment has been for 36 to 72 hours but the Red Book recommends prophylaxis for attachment of 72 hours or more. The latter recommendation should be followed.

I enjoyed reading the article especially since I practice in the Northern VA area and we see a lot of these cases. We have not been giving prophylaxis for tick bites and has been treating them only when symptoms are present. But Dr. Rosenberg is recommending prophylaxis for certain cases and I just want to know where did he get the recommendations? Has the CDC released a formal statement about prophylaxis?
