If your pet has been diagnosed with a condition or disease that can be managed or cured, your veterinarian will discuss treatment options. He or she will recommend drugs that are necessary, safe, and effective for both the individual animal and the specific disorder. For many conditions, there are a variety of drugs that might be considered as an appropriate treatment. When selecting one to prescribe, veterinarians also consider the dose (amount), the method of action, how often to give the chosen drugs, the best way to give the drug, the particular form (for example, pills, liquid, or ointment) to be used, any public health or environmental effects, and local and state regulations.
