For the safest use of long-term medications such as nonsteroidal anti-inflammatory drugs (NSAIDs) and antihistamines, our hospital follows a set policy of periodic blood testing. For example, a patient's blood is tested before the pet begins receiving a medication and again three weeks later and then every three to six months, depending on the drug and the patient's status. To aid client compliance, we place a reminder on the prescription label (e.g. "Blood tests due 4/06" or "Blood tests due before refill").
