Pharmacology of Mextil 500mg Tablet

Cefuroxime is a well-studied and potent antibacterial drug with broad-spectrum bactericidal activity against a variety of infections, including those that produce -lactamases. Cefuroxime is resistant to bacterial -lactamase and thus efficacious against a wide range of ampicillin- and amoxicillin-resistant strains.

Mextil 500mg Tablet Side Effects

Cefuroxime has been linked to a small number of side effects, all of which have been minor and temporary. Rashes and stomach issues have been mentioned as side effects. Prolonged usage of amoxicillin, like other drugs, can lead to the proliferation of non-susceptible organisms like Candida.

Pregnancy & Lactation

Cefuroxime is classified as a pregnancy category B by the US Food and Drug Administration. However, no suitable and well-controlled studies in pregnant women have been conducted. Because animal reproduction studies do not always predict human response, this medication should only be used during pregnancy if absolutely necessary. Human milk has been found to contain cefuroxime. When Cefuroxime is given to a nursing woman, caution should be observed.

Precautions & Warnings

Cefuroxime should be used with caution in individuals who are taking powerful diuretics and have a history of colitis. Although there have been reports of cross-reactions, cephalosporin medicines can often be given safely to patients who are hypersensitive to penicillin. Cefuroxime has proven that at the recommended dose levels, this is unlikely to be an issue.
