DescriptionYour chemotherapy treatment is called erlotinib (er-LA-tin-nib) or Tarceva® (tar-SEA-va). It is commonly used to treat non-small lung cancer and has also been used to treat other diseases. Erlotinib is a new kind of anti-cancer drug called a tyrosine kinase inhibitor. This drug prevents cancer cells from dividing and growing, and can eventually cause the cancer cells to shrink and die.
What Do I Need to Know Before Starting Treatment?Be sure to tell your healthcare provider about any prescription or over-the-counter products you are taking, including dietary supplements, vitamins, herbal medicines and homeopathic remedies. Use an effective birth control method while you are taking these drugs. Erlotinib can cause harm to a fetus, so be sure to tell your healthcare provider right away if you or your partner becomes pregnant. Avoid breastfeeding during treatment. It is not known if erlotinib passes into breast milk. Some chemotherapy drugs can cause sterility. Talk with your healthcare provider about your options if you want to have children in the future. Do not get any immunizations or vaccinations while taking chemotherapy drugs without the approval of your healthcare provider. Chemotherapy can sometimes cause changes in the amount of electrolytes in your body, such as sodium, potassium and magnesium. Your healthcare provider will check your blood for these changes and will treat any problems that are found.
What Do I Need to Know Before Starting Erlotinib?Erlotinib commonly causes a mild to moderate rash or dry skin that affects skin areas above the waist. Typically, the rash develops about eight to ten days after the start of treatment. Tell your healthcare provider if your rash is severe. In rare cases, erlotinib can cause Stevens-Johnson syndrome or toxic epidermal necrolysis, two serious skin conditions. Tell your healthcare provider immediately if you develop a rash that looks like pimples or blisters on the skin, in the mouth or on the genitals or if you develop swelling around the eyes. Erlotinib can cause gastrointestinal perforation (holes in the stomach, intestines or colon) that must be repaired through surgery. You may be at higher risk for this side effect if you have peptic ulcers, diverticulitis or if you are taking an NSAID such as ibuprofen. Call your healthcare provider right away if you have abdominal pain with nausea, vomiting, blood in your stool, constipation or fever. In rare cases, erlotinib can cause a serious lung disease called interstitial lung disease. Tell your healthcare provider if you suddenly have shortness of breath, a cough or a fever. The skin conditions, gastrointestinal perforation and lung disease caused by erlotinib can be severe and life- threatening. Erlotinib can cause eye problems, such as conjunctivitis, keratitis (inflammation of the cornea) and ulcers on the cornea. These side effects can cause vision problems. Tell your healthcare provider immediately if you have eye pain during treatment. Erlotinib can cause problems with liver and kidney function. In rare cases, erlotinib can cause liver or kidney failure. Your healthcare provider will check your kidneys and liver regularly to make sure they are working properly. Your treatment can interact with other substances, including:
- Rifabutin (Mycobutin®), rifampin (Rifadin®) or isoniazid
- Phenytoin (Dilantin®), carbamazepine (Tegretol®) or phenobarbital (Luminal® or Solfoton®)

How Is the Treatment Given?Erlotinib is usually taken once a day. You should take erlotinib one hour before a meal or two hours after a meal. Do not take erlotinib with food. Try to take erlotinib at around the same time every day. If you miss a dose, skip it and take the next dose as scheduled. Do not take two doses of erlotinib at the same time. It is important to take erlotinib exactly as prescribed. Do not stop the medicine or change the dose on your own without talking with your healthcare provider. Store erlotinib at room temperature away from children and pets. If you take too much erlotinib, contact your healthcare provider, local poison control center or emergency room right away. Do not share erlotinib with others. Sharing this medication with anyone else could be harmful.
