Erlotinib is a cancer treatment drug and is also known by its brand name, Tarceva (pronounced tar-see-vah).
It is a treatment for:
- non small cell lung cancer (NSCLC) that has spread
- pancreatic cancer that has spread – alongside the chemotherapy drug gemcitabine
How it works
Erlotinib is a type of cancer treatment drug called a tyrosine kinase inhibitor (TKI). It works by blocking particular proteins on cancer cells that encourage the cancer to grow.
Erlotinib blocks proteins called epidermal growth factor receptors (EGFR). Cancers that have these receptors are called EGFR positive. For lung cancer, doctors check your cancer cells to see if they have the receptors before you have this treatment.
Erlotinib may shrink the cancer or stop it growing for a time.
How you have it
Erlotinib is a tablet. You take it once a day, at least 1 hour before eating, or 2 hours after eating.
Taking your tablets
You must take tablets according to the instructions your doctor or pharmacist gives you.
Speak to your pharmacist if you have problems swallowing the tablets.
Whether you have a full or an empty stomach can affect how much of a drug gets into your bloodstream.
You should take the right dose, no more or less.
Never stop taking a cancer drug without talking to your specialist first.
When you have it
You usually carry on taking erlotinib for as long as it is still working.
Tests during treatment
You have blood tests before starting treatment and during your treatment. They check your levels of blood cells and other substances in the blood. They also check how well your liver and kidneys are working.
