Treats Disease/Condition

Uses

Ado-trastuzumab emtansine is used alone to treat certain types of breast cancer. This medication is used to treat tumors that produce more than the normal amount of a certain substance called HER2 protein. This medication is called a monoclonal antibody and microtubule inhibitor conjugate. Ado-trastuzumab emtansine works by attaching to the HER2 cancer cells and blocking them from dividing and growing. It may also destroy the cancer cells or signal the body (immune system) to destroy the cancer cells.

How To Use

Ado-trastuzumab emtansine may also be called trastuzumab emtansine. However, ado-trastuzumab emtansine is not the same as trastuzumab. Do not substitute trastuzumab for ado-trastuzumab emtansine. This medication is given by slow injection into a vein by a health care professional. It is given as directed by your doctor, usually once every 3 weeks. Your first infusion will be given over at least 90 minutes. The dosage, the speed of your injection, and the length of time you receive ado-trastuzumab emtansine is based on your body weight, medical condition, and response to treatment. To get the most benefit from this medication, do not miss any doses. To help you remember, mark the days on the calendar when you need to receive the medication. Your doctor may prescribe other medications (such as acetaminophen, diphenhydramine) for you to take before the start of your treatment to help prevent serious side effects.

Side Effects

Diarrhea, redness/irritation at the injection site, dizziness, muscle/joint/back pain, stomach/abdominal pain, constipation, trouble sleeping, nausea, vomiting, mouth sores, dry mouth, changes in taste, and loss of appetite may occur. Nausea and vomiting can be severe. In some cases, your doctor may prescribe medication to prevent or relieve nausea and vomiting. Eating several small meals, not eating before treatment, or limiting activity may help lessen some of these effects. If any of these effects persist or worsen, tell your doctor or pharmacist promptly. Tell your doctor right away if you have any serious side effects, including: bone pain, increased coughing, swelling of the hands/ankles/feet, unusual tiredness, severe headache, tingling/numbness (such as in the hands, feet, leg), mental/mood changes, fast/pounding heartbeat, muscle cramps, easy bruising/bleeding. This drug has caused very serious (rarely fatal) bleeding. Get medical help right away if you develop symptoms of very serious bleeding, including: weakness on one side of the body, slurred speech, vision changes, confusion, severe stomach/abdominal pain, trouble breathing, vomit that is bloody or looks like coffee grounds, black/tarry stool. This medication may lower your ability to fight infections. This may make you more likely to get a serious (rarely fatal) infection or make any infection you have worse. Tell your doctor right away if you have any signs of infection (such as fever, chills, persistent sore throat, cough). This medication can sometimes cause a serious infusion reaction with serious lung problems. Immediately tell your doctor of the following side effects that occur while this drug is being given or within 24 hours after your treatment is finished, such as chills, fever, flushing, wheezing, shortness of breath, nausea, headache, dizziness, fainting, rash, and weakness. Ado-trastuzumab emtansine can commonly cause a rash that is usually not serious. However, you may not be able to tell it apart from a rare rash that could be a sign of a severe reaction. Therefore, tell your doctor right away if you develop any rash. A very serious allergic reaction to this drug is rare. However, get medical help right away if you notice any symptoms of a serious allergic reaction, including: rash, itching/swelling (especially of the face/tongue/throat), 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.
