What injection site reactions can patients get with Ajovy (fremanezumab)?
Ajovy (fremanezumab) can cause local reactions where the injection is given. Common injection site reactions include pain, redness (erythema), and swelling. These reactions are typically mild to moderate and usually improve on their own without stopping treatment [1].
How long do Ajovy injection site reactions last?
The available prescribing information describes injection site reactions as short-term and generally resolving with continued use or after the dose, rather than lasting chronically [1]. If reactions are persistent, worsening, or severe, patients are advised to contact their clinician.
How do injection site reactions compare with other Ajovy side effects?
Injection site reactions are among the more commonly reported issues associated with Ajovy. Other side effects that may occur include hypersensitivity reactions, but those go beyond “injection site” symptoms and require different attention if they involve systemic symptoms (for example, rash away from the injection site, trouble breathing, or swelling) [1].
What should patients do if the injection site reaction is bad?
Patients should follow their healthcare professional’s instructions for managing injection site symptoms and watch for signs of a more serious allergic reaction. Seek urgent care if there are symptoms such as hives, facial/lip/tongue swelling, or breathing difficulty [1].
Does the route (self-injection) change injection site reactions?
Ajovy is given as a subcutaneous injection (self-administered or administered by a caregiver). Injection site reactions are specifically tied to that subcutaneous injection, so the type and location of the reaction are expected to be local to the injection site regardless of who performs the injection [1].
