Carcinogenesis, Mutagenesis, Impairment of FertilityTeratogenic Effects of Drugs. Doxycycline is virtually completely absorbed after oral administration.Following a 200 mg dose, normal adult volunteers averaged peak serum levels of 2.6 mcg/mL of doxycycline at 2 hours, decreasing to 1.45 mcg/mL at 24 hours.
The disease is more common in the coastal Atlantic states from April to September, although infections may occur year-round further south3 The wood tick (Dermacentor andersoni) is the principal vector in th… Updated Analysis of risk factors for fatal Rocky Mountain Spotted Fever: evidence for superiority of tetracyclines for therapy. Absorption of tetracyclines is impaired by antacids containing aluminum, calcium, or magnesium, and iron-containing preparations. Evidence of embryotoxicity has also been noted in animals treated early in pregnancy.
The absorption of doxycycline is not markedly influenced by simultaneous ingestion of food or milk.Studies to date have indicated that administration of doxycycline at the usual recommended doses does not lead to excessive accumulation of doxycycline in patients with renal impairment.Uncomplicated gonococcal infections in adults (except anorectal infections in men): 100 mg, by mouth, twice a day for 7 days.
Other mechanisms may exist as well, such as inhibition of leukotriene synthesis, lysosomal enzyme release, lipoxygenase activity, neutrophil aggregation, and various cell membrane functions. 2002
Chloramphenicol … Blood tests can confirm the diagnosis, but only two to three weeks after the onset of infection.
Doxycycline (Monodox, Vibramycin, others) is the most effective treatment for Rocky Mountain spotted fever, but it's not a good choice if you're pregnant.

Doxycycline became the preferred drug choice for treating children of any age because of the potential for severe or fatal cases.Short courses of doxycycline to treat RMSF do not cause significant dental staining.Empiric antimicrobial therapy must be comprehensive and should cover all likely pathogens in the context of the clinical setting.Doxycycline is the drug of choice for Rocky Mountain spotted fever (RMSF).

Letter: Possible needle-associated Rocky Mountain spotted fever.
Chloramphenicol is an alternative, although doxycycline is preferable because tetracyclines have been shown to be associated with a higher survival rate than chloramphenicol.Doxycycline therapy also treats Lyme disease, ehrlichiosis, and relapsing fever—entities often clinically confused with RMSF.In 1997, the American Academy of Pediatrics revised treatment options for children with RMSF.
• Amoxicillin and doxycycline belong to different antibiotic drug classes. 0 Blue/Blue Opaque Hard Gelatin Capsule Printed “West-ward 3142” in Black Ink. Children aged 5 to 9 are more likely to be infected than any other age group. Accessed July 25, 2013.
Corticosteroids suppress active disease, which is assumed to be due to inflammatory mechanisms.This agent decreases autoimmune reactions, possibly by suppressing key components of the immune system.Loteprednol etabonate decreases inflammation by suppressing migration of polymorphonuclear leukocytes and reversing increased capillary permeability. The usual dose of oral doxycycline is 200 mg on the first day of treatment (administered 100 mg every 12 hours) followed by a maintenance dose of 100 mg/day. Chen LF, Sexton DJ.
