Patient leaflet - Tarceva 100 mg film coated tablets

1. What Tarceva is and what it is used for

Tarceva contains the active substance erlotinib. Tarceva is a medicine used to treat cancer by preventing the activity of a protein called epidermal growth factor receptor (EGFR). This protein is known to be involved in the growth and spread of cancer cells.

Tarceva is indicated for adults. This medicine can be prescribed to you if you have non-small cell lung cancer at an advanced stage. It can be prescribed as initial therapy or as therapy if your disease remains largely unchanged after initial chemotherapy, provided your cancer cells have specific EGFR mutations. It can also be prescribed if previous chemotherapy has not helped to stop your disease.

This medicine can also be prescribed to you in combination with another treatment called gemcitabine if you have cancer of the pancreas at a metastatic stage.

2. What you need to know before you take Tarceva

Do not take Tarceva:

  • if you are allergic to erlotinib or any of the

    ingredients of this medicine (listed in section 6).

Warnings and precautions:

  • if you are taking other medicines that may

    increase or decrease the amount of erlotinib in your blood or influence its effect (for example antifungals like ketoconazole, protease inhibitors, erythromycin, clarithromycin, phenytoin, carbamazepine, barbiturates, rifampicin, ciprofloxacin, omeprazole, ranitidine, St. John’s Wort or proteasome inhibitors), talk to your doctor. In some cases these medicines may reduce the efficacy or increase the side effects of Tarceva and your doctor may need to adjust your treatment. Your doctor might avoid treating you with these medicines while you are receiving Tarceva.

  • if you are taking anticoagulants (a medicine

    which helps to prevent thrombosis or blood clotting e.g. warfarin), Tarceva may increase your tendency to bleed. Talk to your doctor, he will need to regularly monitor you with some blood tests.

  • if you are taking statins (medicines to lower

    your blood cholesterol), Tarceva may increase the risk of statin related muscle problems, which on rare occasions can lead to serious muscle breakdown (rhabdomyolysis) resulting in kidney damage, talk to your doctor. ● if you use contact lenses and/or have a

    history of eye problems such as severe dry eyes, inflammation of the front part of the eye (cornea) or ulcers involving the front part of the eye, tell your doctor.

See also below “Other medicines and Tarceva”

You should tell your doctor:

  • if you have sudden difficulty in breathing

    associated with cough or fever because your doctor may need to treat you with other medicines and interrupt your Tarceva treatment;

  • if you have diarrhoea because your doctor

    may need to treat you with anti-diarrhoeal (for example loperamide);

    • immediately, if you have severe or persistent

      diarrhoea, nausea, loss of appetite, or vomiting because your doctor may need to interrupt your Tarceva treatment and may need to treat you in the hospital;

    • if you have ever had problems with your liver.

      Tarceva may cause serious liver problems and some cases have been fatal. Your doctor may perform blood tests while you are taking this medicine to monitor whether your liver functions properly;

    • if you have severe pain in the abdomen,

      severe blistering or peeling of skin. Your doctor may need to interrupt or stop your treatment;

    • if you develop acute or worsening redness

      and pain in the eye, increased eye watering, blurred vision and/or sensitivity to light, please tell your doctor or nurse immediately as you may need urgent treatment (see Possible Side Effects below).

    • if you are also taking a statin and experience

      unexplained muscle pain, tenderness, weakness or cramps. Your doctor may need to interrupt or stop your treatment.

4. Possible side effects

Like all medicines, this medicine can cause side effects, although not everybody gets them.

Contact your doctor as soon as possible if you suffer from any of the below side effects. In some cases your doctor may need to reduce your dose of Tarceva or interrupt treatment:

  • Diarrhoea and vomiting (very common:

    may affect more than 1 out of 10 people). Persistent and severe diarrhoea may lead to low blood potassium and impairment of your kidney function, particularly if you receive other chemotherapy treatments at the same time. If you experience more severe or persistent diarrhoea contact your doctor immediately as your doctor may need to treat you in the hospital.

  • Eye irritation due to keratoconjunctivitis

    (very common: may affect more than 1 out of 10 people), conjunctivitis and keratitis (common: may affect up to 1 in 10 people).

  • Form of lung irritation called interstitial lung

    disease (uncommon in European patients; common in Japanese patients: may affect up to 1 in 100 people in Europe and up to 1 in 10 in Japan). This disease can also be linked to the natural progression of your medical condition and can have a fatal outcome in some cases. If you develop symptoms such as sudden difficulty in breathing associated with cough or fever contact your doctor immediately as you could suffer from this disease. Your doctor may decide to permanently stop your treatment with Tarceva.

  • Gastrointestinal perforations have been

    observed (uncommon: may affect up to 1 in 100 people). Tell your doctor if you have severe pain in your abdomen. Also, tell your doctor if you had peptic ulcers or diverticular disease in the past, as this may increase this risk.

    (hepatitis) was observed (may affect up to 1 in 1,000 people). Symptoms may include a general feeling of being unwell, with or without possible jaundice (yellowing of the skin and eyes), dark urine, nausea, vomiting and abdominal pain.
