How does this medication work? What will it do for me?
Everolimus belongs to the class of medications called antineoplastics. It is used to treat certain forms of advanced cancers. It may be used in combination with other medications to treat certain types of advanced breast cancer. It may be used alone to treat pancreatic neuroendocrine tumours or PNET (tumours in the pancreas that produce chemical messengers) that have metastasized (spread) or progressed within the past year. Everolimus is also used to treat renal cell carcinoma (kidney cancer) that has spread, after other medications have been tried.
Everolimus has been granted a notice of compliance with conditions (NOC/c) by Health Canada. This means that Health Canada has approved this medication to be marketed based on promising evidence of effectiveness, but additional study results are needed to verify its effectiveness. An NOC/c is used to allow access to products that are used to treat or prevent serious, life-threatening, or severely debilitating illness.
Everolimus has conditional approval from Health Canada to be used for people with a condition called tuberous sclerosis complex. This approval is conditional, as research shows it may help reduce the growth of giant cell astrocytomas (SEGA, a type of brain tumour) in children over 3 years of age and angiomyolipomas (a type of non-cancerous kidney tumour) in adults over 18 years of age, however additional clinical trials still need to be completed.
Everolimus works by slowing the growth and spread of breast cancer cells, kidney cancer cells and pancreatic cells that produce hormones by blocking key enzymes. It may also reduce the size of brain and kidney tumours that occur with the genetic condition tuberous sclerosis complex.
This medication may be available under multiple brand names and/or in several different forms. Any specific brand name of this medication may not be available in all of the forms or approved for all of the conditions discussed here. As well, some forms of this medication may not be used for all of the conditions discussed here.
Your doctor may have suggested this medication for conditions other than those listed in these drug information articles. If you have not discussed this with your doctor or are not sure why you are taking this medication, speak to your doctor.

It can be harmful for people to take this medication if their doctor has not prescribed it.
How should I use this medication?
The usual adult starting dose of everolimus is 10 mg taken once daily.
The usual starting dose of everolimus for people being treated for SEGA associated with tuberous sclerosis complex (TSC) is based on body size. Your doctor will determine the dose based on body surface area (BSA), a calculation that takes into account the weight and height of the person taking the medication.
Many things can affect the dose of medication that a person needs, such as body weight, other medical conditions, and other medications. If your doctor has recommended a dose different from the ones listed here, do not change the way that you are taking the medication without consulting your doctor.
Everolimus should be taken at approximately the same time every day, preferably in the morning. It may be taken on an empty stomach or with a small, fat-free meal. Regardless of whether it is taken with food or not, everolimus should be taken the same way, every day to make sure the amount of medication absorbed by the body is consistent.
The tablets should be swallowed whole, with a glass of water. These tablets should not be crushed or chewed.
Avoid drinking grapefruit juice or eating grapefruit, star fruit, or Seville oranges. These foods can slow down how the body gets rid of the medication and may result in too much medication in the body.
It is important that this medication be taken exactly as prescribed by your doctor. If you miss a dose, take it as soon as possible and continue with your regular schedule. If it is more than 6 hours after the time you normally take the medication, skip the missed dose and continue with your regular dosing schedule. Do not take a double dose to make up for a missed one. If you are not sure what to do after missing a dose, contact your doctor or pharmacist for advice.

These factors may affect how you should use this medication.
Anemia: Everolimus may cause low levels of red blood cells. If you experience symptoms of reduced red blood cell count (anemia) such as shortness of breath, feeling unusually tired, or pale skin, contact your doctor as soon as possible.
Your doctor will do blood tests regularly to monitor the number of specific types of blood cells, including red blood cells, in your blood.
Bleeding: Everolimus may cause a reduced number of platelets in the blood, which can make it difficult to stop cuts from bleeding. If you have a medical condition or are taking medication that affects blood clotting, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
If you notice any signs of bleeding, such as frequent nosebleeds, unexplained bruising, vomiting coffee-ground like substances, or black and tarry stools, notify your doctor as soon as possible. Your doctor will order routine blood tests to make sure potential problems are caught early.
Clotting: This medication has been linked to clots in the leg and lungs. If you develop sudden pain with redness and swelling in one of your legs (usually in the calf), sudden difficulty breathing, or coughing up blood, contact your doctor immediately.
Breathing problems: This medication has been linked to inflammation and damage to the lungs. If you develop shortness of breath or a persistent cough, contact your doctor.

Your doctor will do blood tests regularly to monitor the levels of these electrolytes in your blood while you are taking this medication.
