Frequently Asked Questions

AFINITOR® (everolimus) Tablets

In this section you will find answers to questions commonly asked by patients who have been prescribed AFINITOR® (everolimus) Tablets.


AFINITOR is a prescription medicine used to treat adults with a type of pancreatic cancer known as pancreatic neuroendocrine tumor (PNET) that has progressed and cannot be treated with surgery.


AFINITOR is not for use in people with carcinoid tumors that actively produce hormones.

AFINITOR works by blocking the mammalian target of rapamycin (mTOR) protein. In doing so, AFINITOR helps to slow blood vessels from feeding oxygen and nutrients to the tumor. AFINITOR may also affect healthy, nontumor cells. Although AFINITOR has been studied in patients with advanced PNET, how AFINITOR works has been demonstrated only in laboratory studies.

How to Take Treatment

Take AFINITOR once a day at the same time each day. AFINITOR is a prescription medicine that is a once-daily oral tablet. Take AFINITOR exactly as prescribed by your doctor. When you start treatment with AFINITOR, your health care provider may also prescribe a mouthwash to reduce the likelihood of getting mouth ulcers or sores and to reduce their severity. Follow your health care provider’s instructions on how to use this prescription mouthwash. Your doctor may change your dose of AFINITOR or tell you to temporarily interrupt dosing if needed.
