Hypersensitivity
Cautions
Therapy should not be coadministered with estrogen-containing agents as these could interfere with pharmacological action
Routine assessment of 25-hydroxy vitamin D levels prior to the start of aromatase inhibitor treatment should be performed, due to the high prevalence of vitamin D deficiency in women with early breast cancer; women with vitamin D deficiency should receive supplementation with vitamin D
Reductions in bone mineral density (BMD) seen with therapy over time; during adjuvant treatment with exemestane, women with osteoporosis or at risk of osteoporosis should have their bone mineral density formally assessed by bone densitometry at the commencement of treatment; monitor patients for bone mineral density loss and treat as appropriate
Not indicated for breast cancer in premenopausal women
Advise females of reproductive potential to use effective contraception during treatment and for 1 month after final dose
Based on findings in animals, male and female fertility may be impaired by treatment
Pregnancy & Lactation
Pregnancy Category: X
Lactation: Excretion in milk unknown; because of potential for serious adverse reactions in breast-fed infants, advise women not to breastfeed during treatment and for 1 month after final dose
Pregnancy Categories
A: Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.
B: May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk. C: Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done. D: Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk. X: Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist. NA: Information not available.Pharmacology
Mechanism of Action
Aromatase inhibitor - blocks conversion of androgens to estrogens by binding to the heme group of aromatase enzyme, which in turn inhibits its activity

EXEMESTANE - ORAL
(ex-em-ESS-tain)
COMMON BRAND NAME(S): Aromasin
USES: This medication is used to treat certain types of breast cancer (such as hormone-receptor-positive breast cancer) in women after menopause. Exemestane is also used to help prevent the cancer from returning. Some breast cancers are made to grow faster by a natural hormone called estrogen. Exemestane decreases the amount of estrogen the body makes and helps to slow or reverse the growth of these breast cancers.Exemestane is usually not used in women of childbearing age.
HOW TO USE: Read the Patient Information Leaflet provided by your pharmacist before you start using exemestane and each time you get a refill. If you have any questions, consult your doctor or pharmacist.Take this medication by mouth, usually once daily with food (after a meal), or as directed by your doctor.Dosage is based on your medical condition, response to treatment, and other medications you may be taking. Be sure to tell your doctor and pharmacist about all the products you use (including prescription drugs, nonprescription drugs, and herbal products).Use this medication regularly to get the most benefit from it. To help you remember, take it at the same time each day.Since this drug can be absorbed through the skin and lungs, women who are pregnant or who may become pregnant should not handle this medication or breathe the dust from the tablets. (See also Precautions section.)Inform your doctor right away if your condition worsens (such as you get new breast lumps).
SIDE EFFECTS: Hot flashes, hair loss, joint/bone/muscle pain, tiredness, unusual sweating, nausea, diarrhea, dizziness, and trouble sleeping may occur. If any of these effects last or get worse, notify your doctor or pharmacist promptly.Remember that this medication has been prescribed because your doctor has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.Tell your doctor right away if you have any serious side effects, including: nausea/vomiting that doesn't stop, bone fractures, mental/mood changes (such as depression, anxiety), vaginal bleeding, unusual tiredness, dark urine, yellowing eyes/skin.This medication (and cancer) may rarely cause serious problems from blood clots (such as heart attack or stroke). Get medical help right away if you experience: sudden shortness of breath, chest/jaw/left arm pain, confusion, coughing up blood, sudden dizziness/fainting, pain/swelling/warmth in the groin/calf, tingling/weakness/numbness in the arms/legs, trouble speaking, swelling of arms/legs, weakness on one side of the body, vision changes, sudden/severe headache.A very serious allergic reaction to this drug is rare. However, get medical help right away if you notice any of the following symptoms of a serious allergic reaction: rash, itching/swelling (especially of the face/tongue/throat/neck), severe dizziness, trouble breathing.This is not a complete list of possible side effects. If you notice other effects not listed above, contact your doctor or pharmacist.In the US -Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088 or at www.fda.gov/medwatch.In Canada - Call your doctor for medical advice about side effects.
