The U.S. Food and Drug Administration (FDA) is reporting a shortage of three pain relief drugs: fentanyl, morphine and hydromorphone.

The shortage is due to upgrades being made at a pharmaceutical manufacturing plant in Kansas, and is unrelated to any federal policies on opioids or manufacturing quotas, according to FDA officials. You can find full details about the shortage on the FDA’s official drug shortage webpage. The American Veterinary Medical Association (AVMA) received several inquiries about the shortage and expressed concern to the FDA about the impact on animal health and welfare. The FDA is working with manufacturers to rectify the situation.

If any veterinarians are experiencing a shortage, AVMA encourages them to use their professional judgment in treating patients with the resources they have available.
