A 2003 study showed that fluoroquinolone was preferred over amoxicillin, however, for uncomplicated cystitis in young women.
Allocation of the oral amoxicillin and placebo was reported as being double blind.
Aminopenicillins such as ampicillin and amoxicillin have an extended spectrum of action compared with the natural penicillins; extended spectrum penicillins are effective against a wider range of bacteria.
Amoxicillin has a lower incidence of diarrhea than ampicillin and is the preferred drug in most cases.
Children under age eight are usually given amoxicillin (Amoxil, Pentamox, Sumox, Trimox) because tetracycline discolors permanent teeth that have not yet come in.
Examples of penicillins are penicillin V (Beepen-VK, Pen-Vee K, V-cillin K, Veetids) and amoxicillin (Amoxil, Polymox, Trimox, Wymox).
For example, the antibodies of a child allergic to penicillin may cross-react with the antibiotic amoxicillin or nafcillin.
If the child has a weakened immune system, the doctor will prescribe either amoxicillin or erythromycin.
If the decision is made to use an antibiotic, the usual recommendation is for amoxicillin, preferably at a dose of 80 to 90mg/kg/day.
If you become pregnant while taking amoxicillin, call your doctor.
Newer penicillins are resistant to stomach acid, such as penicillin V, or have a broader spectrum, such as ampicillin and amoxicillin.
Oral amoxicillin or cephalosporins are often administered first in treating milder cases of pneumococcal pneumonia in children younger than age five, though they are not used in newborns.
The drug Augmentin, for example, contains a combination of amoxicillin and a beta-lactamase inhibitor, clavulanic acid.
These include penicillin, ampicillin, and amoxicillin; sulfisoxazole or sulfamethoxazole; trimethoprim; nitrofurantoin; cephalosporins; or fluoroquinolones.
