About Floxacillin (Na)

Floxacillin (Na) is a penicillinase resistant, semisynthetic penicillin which has been used primarily in the treatment of infections due to benzylpenicillin-resistant staphylococci. Penicillins are active against most bacteria especially gram positive pathogen (streptococci, staphylococci, pneumococci), some negative starins (gonococci, meningoccocci), some spirochetes and some fungi. The structure of flucloxacillin consists of a thiazolidine ring connected to a ß lactam ring, which is attached to a side chain. Antibiotics require constant drug level in body for therapeutic effect. This is achieved by taking the drug at regular interval of time throughout the day and night as prescribed. Floxacillin (Na) is important to take the drug for the full time period as prescribed. If you discontinue the drug it may result in ineffective treatment.

Warnings

Before initiating therapy with flucloxacillin, careful inquiry should be made concerning previous hypersensitivity reactions to beta-lactams. Cross-sensitivity between penicillins and cephalosporins is well documented. Special caution is essential in the newborn because of the risk of hyperbilirubinemia. Studies have shown that, at high dose following parenteral administration, flucloxacillin can displace bilirubin from plasma protein binding sites, and may therefore predispose to kernicterus in a jaundiced baby. In addition, special caution is essential in the newborn because of the potential for high serum levels of flucloxacillin due to a reduced rate of renal excretion.

High Risk Groups

Drug should not be given to Pregnant Mothers, and patients suffering from Kidney dysfunction.If prescribing authority justifies the benefits of the drug against the possible damages he/she should reevaluate them and consult the reference material and previous studies.
