Treating cancer pain in dogs and cats
No matter the type of cancer, pain is common at various stages, causing not only suffering but also other adverse physiological effects. Make sure you're aware of and are using the best management options—from surgery to radiation to drugs.

Combination therapy and drug interactions

A multimodal approach is best suited for treating and alleviating cancer pain, often combining two or more analgesics for moderate-to-severe, refractory pain. Use caution when treating geriatric patients with a variety of agents, and introduce new drugs one at a time, in a sequential manner.4 When side effects are encountered or if a drug is used at its maximum safe dose without benefit to a patient, its use should be discontinued.4 Carefully evaluate the possibility of pharmacokinetic or pharmacodynamic drug interactions whenever multiple drugs are used concurrently.
