Vets prescribe amoxicillin, an antibiotic derived from penicillin, for bacterial infections such as cuts and wounds, bladder infections and respiratory infections. While the ordering vet will prescribe the appropriate dose for your dog, the common dosing protocol is 5 to 12 mg (0.077 to 0.185 grains) per 454 g (1 lb) of body weight two or three times per day. Dog owners should always follow the veterinarian's instructions for administering amoxicillin or any other medication.
Forms of amoxicillin
There are several commercial forms of amoxicillin available including generic formulas. Amoxicillin is available in oral tablet form with various dosages for dogs of all sizes. The drug is also available as a liquid which is also given to the dog orally. Liquid amoxicillin may require refrigeration and should be shaken before use. Amoxicillin tablets are available in 50 to 400 mg (0.77 to 6.17 grains) doses. Vets often prescribe a combination of pills to get the proper dose for the size of the dog.
Course of treatment
Amoxicillin and other antibiotics are often prescribed for a week or longer depending on the condition and how the disease is responding to treatment. Continue the treatment even if the condition seems to have cleared. This helps prevent the bacteria from becoming resistant to the antibiotic. Amoxicillin is only available by prescription. The pet owner should always follow the instructions from the vet.
Dogs that are allergic to penicillin are also allergic to amoxicillin. According to the website vetinfo.com symptoms of an allergic reaction can include breathing difficulty and shock. Veterinarian treatment is necessary for such cases. Other side effects of amoxicillin and other antibiotics are diarrhoea and flatulence. These problems occur when amoxicillin kills the good bacteria in the dog's digestive tract.
The vet will consider the other drugs the dog is prescribed before adding amoxicillin to the mix. Amoxicillin can interact with some prescription drugs including the antibiotics tetracycline and chloramphenicol. Make sure the vet is aware of all drugs the dog is given.
Amoxicillin is an antibiotic and its effectiveness is limited to the treatment of bacterial infections. Amoxicillin is not effective in the treatment of viral infections, fungal infections or parasites. Vets have other courses of treatment available for these conditions.
