Amoxicillin is an antibiotic used to treat bacterial infections of all sorts. A veterinarian must prescribe amoxicillin for cats, which can be administered in either pill or liquid form. Some cats experience side effects or allergic reactions to amoxicillin, yet these cases are rare.
Originally prescribed for humans, amoxicillin is a more advanced form of penicillin. It is better able to resist stomach acid, lasts longer in the body, and can kill a wider range of bacteria. Amoxicillin is widely prescribed for humans and animals. Some types of bacteria, however, such as the Staphylococcus bacteria, have become resistant to it.
Many types of bacterial infections in cats can be treated with amoxicillin. Infections may arise from cuts, bites, and ear problems, and include dental and urinary tract infections. Amoxicillin works by inhibiting the formation of bacterial cell walls, thereby destroying unwanted bacteria. Amoxicillin for cats, like all antibiotics, is ineffective against viral infections or parasitic infections, such as intestinal worms.
This drug can only be obtained by prescription from a veterinarian. Amoxicillin for cats can be administered in pill form or as a liquid, the dosage being calculated by weight, with 5 to 10 milligrams per pound administered every 12-24 hours. A veterinarian must decide the exact dosage amounts, and the cat should complete the entire prescribed amount of amoxicillin even if their symptoms subside.
Generally, the side effects of amoxicillin for cats are mild. They may include digestive upset, such as nausea, vomiting, or diarrhea. Yeast or fungal infections are also not uncommon. More severe side effects include unusual bleeding, seizures, or fainting. In these cases medication should be stopped, and a veterinarian should be consulted.
In rare cases, a cat may experience an allergic reaction to amoxicillin. Symptoms include hives, swelling of the face or tongue, or shortness of breath. A veterinarian should be contacted immediately if a cat experiences any of these side effects.
Before prescribing amoxicillin, a veterinarian should be informed about any medications a pet is taking. Cats should not be on any other type of antibiotic while taking this drug. Amoxicillin can also interact poorly with other drugs. Cats with stomach or intestinal problems or kidney disease should be given amoxicillin only with caution, as it can cause complications with these conditions.
