<<Prev Post Operative Treatment: Analgesia Next>> Analgesia may be needed for 48-72 hours post-op with major extractions. In severe cases, full agonist or partial agonist opioids may require hospitalisation. NSAID's can be used in addition to this regime. These not only limit pain and discomfort, but also help reduce swelling post-operatively. Both carprofen and meloxicam can be used parenterally on the day of surgery. Use of all NSAID's assumes good renal and hepatic health. Other NSAID's can be used either parenterally or orally on subsequent days.   Commonly used non-steroidal analgesics   Dog Morphine 0.25-1 mg/kg every 4 to 6 hours.
