Afinitor (Everolimus) Medication Information


Afinitor is a kinase inhibitor indicated for the treatment of patients with: 

  • advanced renal cell carcinoma (RCC) after failure of treatment with sunitinib or sorafenib. 
  • subependymal giant cell astrocytoma (SEGA) associated with tuberous sclerosis (TS) who require therapeutic intervention but are not candidates for curative surgical resection. The effectiveness of Afinitor is based on an analysis of change in SEGA volume. Clinical benefit such as improvement in disease-related symptoms or increase in overall survival has not been demonstrated. 


There are oral tablets available in several different strengths:

  • 2.5 mg
  • 5 mg
  • 10 mg

  • Stomatitis

Speak with your doctor or pharmacist for a full list of side effects that applies to you.


Consider a diagnosis of non-infectious pneumonitis in patients presenting with non-specific respiratory signs and symptoms such as hypoxia, pleural effusion, cough, or dyspnea, and in whom infectious, neoplastic, and other causes have been excluded by means of appropriate investigations. Patients should promptly report any new or worsening respiratory symptoms.

Afinitor has immunosuppressive properties and may predispose patients to bacterial, fungal, viral, or protozoal infections, including infections with opportunistic pathogens. While taking Afinitor, be vigilant for signs and symptoms of infection; if a diagnosis of an infection is made, institute appropriate treatment promptly and consider interruption or discontinuation of Afinitor.

Mouth ulcers, stomatitis, and oral mucositis have occurred in patients treated with Afinitor. If ulcerations develop, topical treatments are recommended, but alcohol- or peroxide-containing mouthwashes should be avoided as they may exacerbate the condition.
