Amoxicillin for Cat Urinary Infections

Amoxicillin is a generic prescription medication related to the drug penicillin, which is used to treat infections in humans and animals. For cats, veterinarians often prescribe the drug for urinary tract or bladder infections.

  1. Function

    • Amoxicillin works by preventing bacteria from producing chemicals needed to create a structure that surrounds and protects its cells called a cell wall. Without these chemicals, the bacteria in the urinary tract eventually die, clearing up the infection.

    Dose

    • For urinary infections, veterinarians typically prescribe 5mg to 12mg of amoxicillin for every pound a cat weights, reports PetPlace.com.

    Time Frame

    • Most urinary infections respond to treatment with antibiotics like amoxicillin within two days, causing symptoms to decrease or disappear, reports Mar Vista Animal Medical Center. Typically, the drug is needed for 10 to 14 days to completely eliminate the infection.

    Side Effects

    • Nausea and diarrhea are possible side effects of amoxicillin use for the treatment of urinary infections in cats, reports PetPlace.com.

    Warning

    • Because the drugs are related, never give amoxicillin to a cat that has previously had an allergic reaction to penicillin.
