Choosing The Right Antibiotic for Bacterial Infections. There Are So Many Different Antibiotics: Azithromycin, Ciprofloxacin, Amoxicillin, Doxycycline, Levofloxacin, etc.


The use of antimicrobials in the treatment of infection is one of the triumphs of modern medicine. Antibiotics halt bacterial growth and cure infection through two main mechanisms. Antibiotics are either bactericidal or bacteriostatic. For most doctors, the choice ultimately depends on the seriousness of the infection, the antibiotics that are readily available, the most cost effective treatment, and the drug that will cause the fewest side effects.

Doctors are sometimes faced with difficult choices. The problem of antibiotic resistance is always an important consideration. Widespread use of broad spectrum antibiotics is one factor that is thought to have helped the spread of antibiotic resistance and doctors aim to prescribe antibiotics sensibly so that antibiotic resistance does not increase further. To overcome bacterial resistance, some drugs combine a beta-lactam antibiotic and a beta-lactamase inhibitor, thus creating a stable, new compound with good activity against bacteria.


The recommended duration of antimicrobial treatment for common bacterial infections is 10 to 14 days. The infection resolves spontaneously in about 45% of adults. Doctors reduce the use of antibiotics for nonbacterial infections, and encourage the appropriate use of antibiotics when bacterial disease is likely.

Adoxa, Doryx - Doxycycline 100 mg

Doxycline is usually supplied as the hydrochloride or the hyclate. Doxycline is recommended for use against against a wide variety of infections when susceptibility is demonstrated. Typically treatment begins with 2 doses of 100 miligrams on the first day followed by two doses of 50 milligrams on following days. Doxycline may interact with anticoagulants and its effectiveness is lowered by over the counter antacids and bismuth subsalicylate, barbiturates, the anticonvulsants carbamazepine and phenytoin.

Zithromax - Azithromycin 250 mg / 500 mg

It is an azalide antibiotic, a subclass of the macrolides. It retains the spectrum of activity of erythromycin against Gram-positive and Gram-negative pathogens and has increased activity against many Gram - negative and atypical microorganisms. The drug should be taken 1 hour before or at least 2 hours after a meal. Patients can find cheap Zithromax and order Zithromax (Azithromycin) at discount prices at some online stores.

Cipro - Ciprofloxacin 250 mg / 500 mg / 750 mg

Cipro (Ciprofloxacin) is an oral antibiotic used to treat susceptible bacterial infections in multiple animal species. Ciprofloxacin is effective in-vitro against virtually all gram-negative pathogens, including Pseudomonas aeruginosa. It is also effective against gram-positives such as staphylococci and streptococci. Ciprofoxacin is absorbed from the intestinal tract and is carried by the bloodstream to many tissues of the body where it kills susceptible bacteria. To be effective, ciprofloxacin must be given multiple days in a row.

Amoxil - Amoxicillin 500 mg

Amoxil is an antibiotic of penicillin drug group which is widely used in treatment of a broad variety of infections such as: skin infections, middle ear infections, gonorrhea, upper and lower respiratory tract infections, including infections of the genital and urinary tract. The disease may reoccur in case of incomplete course of Amoxil and as well the chance of bacteria resistance to Amoxil or similar antibiotics may be increased.

Levaquin - Levofloxacin 250 mg / 500 mg

Levaquin is a synthetic antibacterial drug used for the treatment of lung, sinus, skin, urinary tract infections, severe bronchial infections, infectious diarrhea, typhoid fever, and pneumonia. Levaquin belongs to the family of Flouroquinolone, which are effective against many organisms that traditional antibiotics fail to resist. Levaquin kills a variety of bacteria, and prevent them from reproducing and is often used to treat infections all over the body.

Flagyl - Metronidazole 250 mg

Flagyl tablets contain the active ingredient metronidazole, which is a type of medicine called an antibiotic. Metronidazole kills a wide variety of bacteria that are known collectively as anaerobic bacteria. erobic bacteria can cause infections in areas of the body such as the bones, gut, pelvic cavity and gums.
