MEMORANDUM

Arthur Torlucci, a California state prisoner, appeals pro se from the district court’s order dismissing his 42 U.S.C. § 1983 action alleging deliberate indifference to his medical needs and safety when defendants assigned him to a double cell and discontinued his anxiety medication. We have jurisdiction under 28 U.S.C. § 1291 . We review de novo, Nelson v. City of Irvine, 143 F.3d 1196, 1200 (9th Cir.1998), and we affirm.

The district court properly dismissed Torlucci’s action because Torlucci failed to allege facts showing that defendants acted with conscious disregard to an excessive risk to his heath or safety. See Toguchi v. Chung, 391 F.Sd 1051, 1057 (9th Cir.2004) (a prison official acts with deliberate indifference only if he or she knows of and disregards an excessive risk to the prisoner’s health and safety); see also Jackson v. McIntosh, 90 F.3d 330, 332 (9th Cir.1996) (a difference of opinion between the physician and the prisoner concerning the appropriate course of treatment does not amount to deliberate indifference to serious medical needs). Moreover, the district court properly dismissed Torlucci’s claims against defendants Evelsizor, Hendrick, Rushen, and Sid because Torlucci failed to set forth facts linking defendants to the constitutional violations at issue. See Taylor v. List, 880 F.2d 1040, 1045 (9th Cir.1989) (“Liability under [§ ] 1983 arises only upon a showing of personal participation by the defendant. A supervisor is only liable for the constitutional violations of ... subordinates if the supervisor participated in or directed the violations, or knew of the violations and failed to act to prevent them” (citations omitted)).

We do not consider claims, including Torlucci’s Religious Land Use and Institutionalized Persons Act claim, raised for the first time on appeal. See Padgett v. Wright, 587 F.3d 983 , 985 n. 2 (9th Cir.2009) (per curiam).

Torlucci’s pending motions are denied.

AFFIRMED.
