How does Amoxifur work?
Amoxifur works by inhibiting the formation of bacterial cell walls.
Probenecid decreases the renal tubular secretion of Amoxifur. Concurrent use of Amoxifur and probenecid may result in increased and prolonged blood levels of Amoxifur.
What Is Amoxifur (Amoxil)?
Amoxifur is the generic form of the brand-name drug Amoxil, a drug used to treat bacterial infections.
Doctors prescribe Amoxifur to treat infections caused by bacteria that are sensitive to the drug, including E. coli, staphylococcus, streptococcus, H. influenzae, and H. pylori.
Your doctor may prescribe Amoxifur to treat infections of the skin, throat, ears, nose, stomach, lungs, and urinary tract infections (UTI).
However, the drug will not work against infections caused by viruses such as cold and flu.
Also, guidelines urge doctors to prescribe Amoxifur only when an infection is strongly suspected to be caused by bacteria.
The Food and Drug Administration (FDA) first approved Amoxifur in the 1980s.
Today, different drug companies produce this antibiotic: Brand names include Amoxil and Moxatag.
Q: Is Amoxifur good for a painful boil?
A: Boils do not always require antibiotic therapy, often times they resolve on their own. To properly evaluate the boil and determine if treatment with an antibiotic is necessary, you should consult your health care provider. Amoxifur (Amoxil) is an antibiotic categorized as a penicillin which fights bacteria in your body. Amoxifur is indicated in the treatment of several different types of bacterial infections including ear infections, bladder infections, pneumonia, gonorrhea and E.coli or salmonella infections. Amoxifur is also approved to treat stomach ulcers caused by Helicobacter pylori (H. pylori) infections in combination with other medications, such as Biaxin (clarithromycin) and Prevacid (lansoprazole). Amoxifur is approved to treat some skin infections caused by certain bacteria. Some of the possible side effects associated with Amoxifur treatment include nausea, vomiting, stomach pain, vaginal itching or discharge, headache, swollen, black or hairy tongue or thrush (white patches inside the mouth and throat). Antibiotics, such as Amoxifur, can cause diarrhea. This could be a side effect of the medication or it could indicate a new infection. If you experience diarrhea that is watery, or has blood in it, contact your doctor immediately and do not take any medication to stop the diarrhea unless otherwise instructed. Amoxifur may be taken with or without food. If stomach upset occurs, take Amoxifur with food. Amoxifur should be taken for the entire length of time prescribed by your doctor. Although your symptoms may begin to resolve before the infection is completely treated, do not stop taking Amoxifur until you are finished with the course of therapy. Amoxifur will not treat a viral infection such as a cold or the flu. For more specific information, consult with your doctor or pharmacist for guidance based on your health status and current medications, particularly before taking any action. Beth Isaac, PharmD
What other drugs will affect Amoxifur?
Before giving Amoxifur, tell your veterinarian if your pet is being given another antibiotic (for the same or a different infection), allopurinol, or probenecid. You may not be able to give Amoxifur or you may need to have the dosage adjusted. Drugs other than those listed here may also interact with Amoxifur. Talk to your veterinarian or pharmacist before giving any prescription or over-the-counter medicines, including vitamins, minerals, and herbal products.
Along with their useful effects, most medicines can cause unwanted side-effects although not everyone experiences them. The table below contains some of the most common ones associated with Amoxifur. You will find a full list in the manufacturer's information leaflet supplied with your medicine. The unwanted effects often improve as your body adjusts to the new medicine, but speak with your doctor or pharmacist if any of the following continue or become troublesome.
The concurrent administration of allopurinol and Amoxifur increases the incidence of rashes in patients receiving both drugs as compared to patients receiving Amoxifur alone. It is not known whether this potentiation of Amoxifur rashes is due to allopurinol or the hyperuricemia present in these patients.
Standardized susceptibility test procedures 2,3,4 require use of laboratory controls to monitor and ensure the accuracy and precision of the supplies and reagents used in the assay, and the techniques of the individuals performing the test control. Standard Amoxifur powder should provide the following range of MIC values provided in Table 5 4 . For the diffusion technique the criteria provided in Table 5 should be achieved.

This medication may be prescribed for other uses; ask your doctor or pharmacist for more information.
Amoxifur in vitro susceptibility testing methods for determining minimum inhibitory concentrations (MICs) and zone sizes have not been standardized, validated, or approved for testing H. pylori. Specimens for H. pylori and clarithromycin susceptibility test results should be obtained on isolates from patients who fail triple therapy. If clarithromycin resistance is found, a non-clarithromycin-containing regimen should be used.
