RONALD LEE GILMAN, Circuit Judge. Dr. Timothy Heyd served as the Chief Medical Officer of the prison where Jamal Murray was previously incarcerated and was also Murray’s treating physician. During his time in prison, Murray suffered from a condition known as deepvein thrombosis, which, in Murray’s case, involved the formation of venous blood clots in his legs. Murray relied on the medication Coumadin to abate his condition. After many weeks passed with inadequate monitoring and the prescribing of too low a dosage of Coumadin, Murray suffered from a cerebral blood clot that has left him permanently blind.

Murray timely brought an Eighth Amendment claim under 42 U.S.C. § 1983 against Dr. Heyd for deliberate indifference to Murray’s serious medical needs. Dr. Heyd sought qualified immunity in a motion for summary judgment, which the district court denied. He now seeks a review of that ruling through the present interlocutory appeal. For the reasons set forth below, we AFFIRM the district court’s determination that Dr. Heyd is not entitled to qualified immunity as a matter of law.

JULIA SMITH GIBBONS, Circuit Judge. Cardinal Health, Inc., is one of several defendants named in the multitude of ongoing state and federal lawsuits against opioid manufacturers, distributors, and dispensers seeking damages related to the nation’s opioid epidemic. Cardinal Health sought defense costs under its insurance policies with National Union Fire Insurance (“National Union”), which has continually reserved its right to deny coverage. After Cardinal Health brought a declaratory action in Ohio state court, National Union removed the case to federal court, seeking relief pursuant to the Declaratory Judgment Act. The district court declined to exercise jurisdiction and granted Cardinal Health’s motion to remand to state court. Because the district court did not abuse its discretion, we affirm.
