Widrox is used to treat bacterial infections in many different parts of the body. It belongs to the class of medicines known as cephalosporin antibiotics. It works by killing bacteria or preventing their growth. However, Widrox will not work for colds, flu, or other virus infections.
Widrox is available only with your doctor's prescription.
An indication is a term used for the list of condition or symptom or illness for which the medicine is prescribed or used by the patient. For example, acetaminophen or paracetamol is used for fever by the patient, or the doctor prescribes it for a headache or body pains. Now fever, headache and body pains are the indications of paracetamol. A patient should be aware of the indications of medications used for common conditions because they can be taken over the counter in the pharmacy meaning without prescription by the Physician.
To reduce the development of drug-resistant bacteria and maintain the effectiveness of Widrox (Widrox hemihydrate) Tablets and Widrox (Widrox (Widrox hemihydrate) hemihydrate) Capsules and other antibacterial drugs, Widrox (Widrox hemihydrate) Tablets and Widrox (Widrox (Widrox hemihydrate) hemihydrate) capsules should be used only to treat or prevent infections that are proven or strongly suspected to be caused by susceptible bacteria. When culture and susceptibility information are available, they should be considered in selecting or modifying antibacterial therapy. In the absence of such data, local epidemiology and susceptibility patterns may contribute to the empiric selection of therapy.
Widrox (Widrox (Widrox hemihydrate) hemihydrate) is indicated for the treatment of patients with infection caused by susceptible strains of the designated organisms in the following diseases:
Urinary tract infections caused by E. coli, P. mirabilis, and Klebsiella species.
Skin and skin structure infections caused by staphylococci and/or streptococci.
Pharyngitis and/or tonsillitis caused by Streptococcus pyogenes (Group A beta-hemolytic Streptococci).
Note: Only penicillin by the intramuscular route of administration has been shown to be effective in the prophylaxis of rheumatic fever. Widrox (Widrox (Widrox hemihydrate) hemihydrate) is generally effective in the eradication of streptococci from the oropharynx. However, data establishing the efficacy of Widrox (Widrox (Widrox hemihydrate) hemihydrate) for the prophylaxis of subsequent rheumatic fever are not available.
Note: Culture and susceptibility tests should be initiated prior to and during therapy.
Renal function studies should be performed when indicated.

Positive direct Coombs' tests have been reported during treatment with the cephalosporin antibiotics. In hematologic studies or in transfusion cross-matching procedures when antiglobulin tests are performed on the minor side or in Coombs' testing of newborns whose mothers have received cephalosporin antibiotics before parturition, it should be recognized that a positive Coombs' test may be due to Widrox.
