What is the dosage for doxycycline?

  • The absorption of doxycycline is not markedly affected by food, and
    therefore, it can be taken with meals.
  • For most infections, doxycycline is taken
    once or twice daily for 7 to 14 days.
  • For adult infections, the usual dose of
    oral doxycycline is 200 mg on the first day of treatment (100 mg every 12 hours)
    followed by a dose of 100 to 200 mg/day as a single dose or divided and
    administered twice daily.

Which drugs or supplements interact with doxycycline?

  • It is recommended that doxycycline
    not be taken at the same time as aluminum, magnesium, or calcium based antacids, such as
    Mylanta, Maalox, Tums, or Rolaids because, like food, these medications bind doxycycline in the
    intestine and prevent its absorption. Similarly, doxycycline should not be taken
    with minerals (such as calcium or iron) or with

    bismuth subsalicylate (Pepto Bismol).

  • Doxycycline may enhance the activity of
    warfarin
    (Jantoven, Coumadin) and cause excessive "thinning" of the blood leading to exaggerated
    bleeding, necessitating a reduction in the dose of warfarin.
    Phenytoin (Dilantin),
    carbamazepine
    (Tegretol), and
    barbiturates (such as phenobarbital) may enhance the metabolism
    (destruction) of doxycycline thus making it less effective.
  • Doxycycline may interfere with the action of penicillins and should not be
    combined with penicillins. It may also reduce the effect of
    oral contraceptives.
    Combining tetracycline and methoxyflurane (Penthrane) may reduce kidney
    function.

Is doxycycline safe to use during pregnancy or while breastfeeding?

  • Tetracycline antibiotics, such as doxycycline, can have toxic
    effects on development of bone in the fetus. Therefore, tetracyclines are not
    recommended
    during pregnancy unless there is no other appropriate antibiotic.
  • Doxycycline is secreted into
    breast milk
    but the extent of absorption by the breastfed infant is not known. Since tetracyclines can cause toxic effects on bone, the use of tetracyclines in
    nursing mothers is of concern. The physician must decide whether to recommend
    that a nursing mother discontinue nursing during treatment with tetracyclines or
    change to a different antibiotic.
