General advice on the use of antibiotics
There is no single antibiotic that kills all the different varieties of bacteria. All of the drugs grouped together and called antibiotics only target a limited range of bacteria. Thus, it is very important that you have the right diagnosis because, if you take the wrong antibiotic for the bacteria, protozoa or parasites causing your illness, there will be no effective treatment. In all probability, you will become more ill until your own body’s immune system starts getting results or you begin using the right antibiotic. Secondly, antibiotics have no effect at all on viruses. Thirdly, antibiotics may kill the bacteria, protozoa or parasites, or only prevent their reproduction or slow their growth, i.e. in most cases, it is for your immune system to kill the offending invaders. Finally, you should always take a course of antibiotics to the end. Even though you may start feeling better, it is important for your immune system to kill all the bacteria, protozoa or parasites in your body before the survivors have a chance to build up immunity to the drug. Otherwise, the next time you take this antibiotic, it will be less effective.
Doxycycline as an antibacterial
Doxycycline is one of the tetracycline antibiotics and, as such, treats a moderately wide range of bacterial infections. But, there is increasing evidence that these bacteria are beginning to build resistance and, if you use one tetracycline, there is a risk that the bacteria in your body will develop resistance to all the tetracycline drugs. Thus, you should always finish taking all the drug prescribed even if you feel better. It is essential to kill as many bacteria as possible in your body and reduce the risk of resistance developing.
Doxycycline is used to treat some of the most serious diseases like anthrax, typhus, and some varieties of pneumonia. But, if you have a staphylococcal infection, you must have laboratory tests to confirm the strain of bacteria is susceptible to Doxycycline. More than half the different bacteria are already resistant to Doxycycline. It also treats marginally less serious diseases from the sexually transmitted to acne.
Doxycycline as an antiprotozoal
There are a range of diseases caused by protozoa, single-celled or micro-organisms such as an amoeba. The biologists prefer not to treat all the possible varieties of organism as protozoa. There are only few common denominators. But the medical profession prefers to keep the term while recognizing that the drugs available must be chosen with great care to ensure the right drug is used to treat the right organism. Thus, for example, whereas a disease like malaria has a single cause and a well-known treatment, food poisoning is a broad generalisation with many possible causes. Always get laboratory tests to confirm the identity of the particular cause of your illness before confirming the use of Doxycycline.
Doxycycline as an antihelmintic
Helminths are parasitic worms that can invade your body, living inside your digestive tract and intestinal systems, and taking nourishment from you. The results are physical weakness, vomiting and several increasingly serious diseases. Again, it is vital to have a proper diagnosis before beginning the use of Doxycycline as the antiheminth drug.
When the use of topical lotions and creams has failed, the use of an antibiotic like Doxycycline will often reduce acne or completely cure it.
