Cefpodoxime Proxetil
How to Use this Antibiotic to Treat Skin Infection in Dogs?

The action of cephalosporin antibiotic helps eradicate the bacterial infestation caused by the strains of Pasteurella, E. coli, Staphylococcus, and Streptococcus canis, which cause urinary tract infections.ย 

While the drug is for use among dogs, its off-label usage is prevalent among cats for urinary tract infections treatment. It often happens that a few of the medications are off-label that are in use. Under such circumstances, it is advisable to refer to the guidelines prescribed by your veterinarian about the caution and direction of usage.

Special Precautions

Overdose of cefpodoxime can lead to lack of appetite, diarrhea, lethargy, and vomiting. A few cases of cefpodoxime overdosing can be fatal, and your pet can undergo adverse reactions. It is advisable to contact your veterinarian immediately if such a situation occurs. In the absence of a veterinarian nearby, it is advisable to contact any emergency clinic in your vicinity.

Pets that have an allergy to cephalosporins should not have cefpodoxime. You must not give it to pets with a history of seizures or kidney diseases. Extra caution is essential for giving the drug to nursing animals or pregnant ones.

Mechanism of Action

The drug's actions are highly efficacious against a wide spectrum of bacteria. It specifically helps to tackle gram-positive and gram-negative bacteria. In the presence of beta-lactamase enzymes, cefpodoxime is stable. Due to the higher production of beta-lactamase enzymes in many organisms, they are resistant to cephalosporins and penicillins. However, they may get affected by cefpodoxime.

Studies suggest that cefpodoxime becomes inactive in the presence of an extended spectrum of beta-lactamases. The inhibition of cell wall synthesis brought by cefpodoxime leads to bactericidal activities. The primary constituent of bacterial cell walls or peptidoglycan ceases to produce due to cefpodoximeโ€™s active metabolite binding.

Known Drug Interactions

Cefpodoxime can interact with a few of the drugs and please its absorption. Therefore you need to inform your veterinarian about any ongoing medication for your pet.
