How is perseris administered?

How do you give Perseris to a patient?

Perseris is injected once a month under the skin in the abdomen or upper arm. Healthcare providers must mix the powder and liquid inside the prefilled syringe right before use and then inject it within two minutes.

What training or preparation is required before giving the injection?

Only clinicians who have completed the official Perseris training program should administer the drug. The kit supplies all necessary components, but the two-step mixing process must be followed exactly to avoid clumping or improper dosing.

Can patients give themselves the shot at home?

No. Perseris must be given by a trained healthcare professional in a clinical setting. Self-administration is not approved.

What happens if the injection is delayed or missed?

A missed monthly dose should be given as soon as possible. If more than eight weeks have passed since the last injection, the patient restarts the initiation schedule: one injection per week for the first two weeks, then monthly dosing resumes.

Are there special storage or handling rules?

Unopened kits stay stable at room temperature. Once mixed, the suspension must be used within two minutes or discarded. The drug should never be frozen or exposed to high heat.

Who makes Perseris and when does its patent expire?

Indivior manufactures Perseris. The key U.S. patent listed on DrugPatentWatch.com is set to expire in 2031, though other regulatory exclusivities may extend protection further.
