    Can anyone tell me what side effects they have had with the doxy?

    I have been taking a low dose of doxycycline for about 2 months now. I take 100 mg every other day.

    The only side effect that I've noticed is that I get a bit nauseous when I take it on an empty stomach.

    It can also cause a skin reaction to the sun. I haven't had this issue and I spend a lot of time outdoors in the sun. But I was warned about it and I know that ldbgcoleman reacted to it this way.

    Are you taking it now or considering taking it?

    Good luck to you!

    I took doxy for about 10 days and I became very nauseous. Dr. took me off the doxy.

    Are you experiencing a problem with it?

    Take care,

    From all my posts regarding the Doxy, I had no side effects from taking it as long as I continued to take my Jarro-Dophilus. In fact, the Doxy appears to have stopped the IBS which plagued me for so many years.

    Doxy can be toxic after the expiration date and should be discarded.

    Depending on what one is treating, there are other ABX. I, personally, do not believe Cipro should be the first drug of choice. It's a heavy hitter and can have side effects. I am allergic to fluoride and cannot take any of the fluoroqinolines.

    Hope this helps.

    Love, Mikie

    and I was pleasantly surprised when it cleared a long standing intestinal pain. However it irritated my GI tract, caused nausea and severe diarrhea; primal defence helped with the diarrhea. The doctor who is treating my borreliosis/lyme, and other non viral infections, is now aware of the care needed when Rx ABx.

    I had signs of die off in the early months, but I was not on a high enough dose for it to be really effective long term.

    The only side effect I have noticed from the Doxy is bad nausea a few hours after I take it in the mornings—but I am on a high dosage for lyme (400 mg). I have been taking it about 3 weeks now and my digestion has not been this good in years…somehow it has positively effected my IBS.

    Doxycycline info! 11/27/05 01:56 PM

    How does it work?

    Doxycycline belongs to a group of antibiotics called tetracyclines. It is an antibiotic that has the ability to inhibit the growth of a wide variety of bacteria and certain other organisms. It works by preventing bacteria from producing proteins that are essential to them. Without these proteins the bacteria cannot grow, replicate and increase in numbers. Doxycycline therefore stops the spread of the infection and the remaining bacteria eventually die. Doxycycline is used to treat a wide variety of respiratory, urinary tract, eye and sexually transmitted infections, and various other infections caused by susceptible bacteria and micro-organisms. It is also used for severe acne, as it is active against the bacteria associated with acne, Propionebacterium acnes. This is a common type of bacteria that feeds on sebum produced by the sebaceous glands in the skin. It produces waste products and fatty acids that irritate the sebaceous glands, making them inflamed and causing spots. By controlling bacterial numbers, doxycycline brings the inflammation of the sebaceous glands under control, and the skin is allowed to heal. Doxycycline is also active against the parasite that causes malaria. It is sometimes used to treat malaria, and can also be used to prevent it when visiting high-risk malarial areas, in particular areas where the malaria parasite is resistant to chloroquine.
    What is it used for?

    Acne vulgaris
    Bubonic plague
    Chronic bronchitis
    Death and decay of tissue in a infected wound due to gas production by the infecting bacteria (gas gangrene)
    Disease caused by infection with Leptospira bacteria (Weil's Disease/leptospirosis)
    Disease of rodents and rabbits that can be transmitted to humans (tularaemia)
    Eye infections
    Infection caused by the bacteria brucella (brucellosis)
    Infection of the lungs and airways (lower respiratory tract infection)
    Infections of the urinary system
    Infections with bacteria transmitted by lice, fleas, ticks and mites (rickettsial infections)
    Infectious disease of parrots and man (parrot fever/psittacosis)
    Infectious disease of rodents that can be transmitted to humans (melioidosis)
    Inflammation of the sinuses
    Lesions in the groin and genitalia caused by a sexually transmitted bacteria (granuloma inguinale)
    Louse and tick-bourne relapsing fever
    Prevention of an infectious disease called Scrub typhus
    Prevention of infection with Leptospira bacteria (leptospirosis)
    Prevention of malaria
    Prevention of traveller's diarrhoea (enterotoxigenic E coli)
    Protozoal infection of the intestine (amoebiasis)
    Sexually transmitted infection that causes genital ulcers (chancroid)
    Treatment of malaria caused by chloroquine-resistant Plasmodium falciparum
    This medicine can cause the skin to react abnormally to direct sunlight and UV light, causing an exagerated sunburn reaction. Avoid exposing your skin to direct sunlight and UV light while taking this medicine. Stop taking this medicine and consult your doctor at the first sign of any skin reaction.
    If you are using this medicine as malaria prevention you should start taking it, as directed by your doctor, two days before you travel. You should continue taking it throughout your stay in the malarious region, and for a further four weeks after leaving.
    Doxycycline capsules should be taken with plenty of water while you are sitting or standing. Avoid taking them just before going to bed. This is to prevent the medicine irritating the throat. If you find the medicine irritates your stomach you can minimise this by taking it with food or milk.
    Occasionally this antibiotic may upset the natural balance of micro-organisms in the body, allowing those that are not susceptible to doxycycline to overgrow and cause infection. This may happen with yeasts such as Candida, resulting in thrush infections. If this happens, stop taking this medicine and see your doctor.
    Use with caution in

    Decreased liver function
    Long-term inflammation of skin and some internal organs (systemic lupus erythematosus)
    People taking medicines with potential to cause adverse effects on the liver
    Not to be used in

    Allergy to other tetracycline antibiotics, eg doxycycline, minocycline
    Children under 12 years of age
    This medicine should not be used if you are allergic to one or any of its ingredients. Please inform your doctor or pharmacist if you have previously experienced such an allergy. If you feel you have experienced an allergic reaction, stop using this medicine and inform your doctor or pharmacist immediately.

    Pregnancy and Breastfeeding

    Certain medicines should not be used during pregnancy or breastfeeding. However, other medicines may be safely used in pregnancy or breastfeeding providing the benefits to the mother outweigh the risks to the unborn baby. Always inform your doctor if you are pregnant or planning a pregnancy, before using any medicine.

    This medicine should not be used during pregnancy as it may be harmful to the unborn baby. Seek medical advice from your doctor.
    Significant amounts of this medicine may pass into breast milk. It should not be used by breastfeeding mothers. Discuss this with your doctor.
    Label warnings

    Carrie, I'm excited to find another whose IBS was helped with the Doxy. It's nice to have a positive side effect to a drug.

    Love, Mikie

    When on an ABX, the effects can mimic IBS. Some ABX do disagree with people and it can be trial and error to find the right one.

    Yep severe reaction to the sun! Still have to be careful and I have been on it since late June. I also am slightly nauseous even with food and very nausous If I don't eat enough. But I'm much better in every other area and it's not forever! :) Lynn

    I'll second that about avoiding the sun while on doxy. This summer at our cottage we were having family gatherings on the beach and I was hiding under the trees and still got burnt!!

    I was nauseaous the first few months but now that I'm eating more and drinking lots don't really get any side effects any more.

    I think the doxy is also helping with the IBS because my digestion and stomach are so much better. Also been checking my tongue and the color is getting pinker and the ridges on the sides are gone!

    Against the cell-wall-deficient bacteria, like mycoplasmas and Lyme, which seem to plague us. The doc would not likely prescribe a drug in the penicillin family for them--good news for you.

    The Transfer Factor C targets Lyme and there is one from ProHealth which targets mycoplasmas. Only docs can order the latter. This might be your ace in the hole if you cannot tolerate ABX.

    Good luck.
