6. Contents of the pack and additional information

Erlotinib Tarbis contains the active ingredient erlotinib. This medication is used to treat cancer and works by preventing the activity of a protein called the epidermal growth factor receptor (EGFR). It is known that this protein is involved in the growth and spread of tumor cells.

Erlotinib is indicated for adults. Your doctor may prescribe this medication if you have non-small cell lung cancer in an advanced state. They may prescribe it as initial treatment or as treatment if your disease remains practically unchanged after initial chemotherapy, since your cancer cells have specific mutations in the EGFR. They may also prescribe it if previous chemotherapy has not helped to slow your disease.

Your doctor may also prescribe this medication in combination with another treatment called gemcitabina if you have metastatic pancreatic cancer.

Do not take Erlotinib Tarbis

• if you are allergic to erlotinib or any of the other components of this medication (listed in section 6).

Warnings and precautions

• if you are taking other medications that may increase or decrease the amount of erlotinib in your blood or affect its effect (for example, antifungals such as ketoconazole, protease inhibitors, erythromycin, clarithromycin, phenytoin, carbamazepine, barbiturates, rifampicin, ciprofloxacin, omeprazole, ranitidine, St. John's wort, or proteasome inhibitors), consult your doctor. In some cases, these medications may decrease the effectiveness or increase the effects of this medication and, therefore, your doctor may need to adjust your treatment. Your doctor should avoid treating you with these medications while you are taking Erlotinib Tarbis.
• if you are taking anticoagulants (medications that help prevent the formation of blood clots or coagulation, for example, warfarin) since Erlotinib Tarbis may make you more prone to bleeding. Consult your doctor, who will need to perform regular blood tests.
• if you are taking statins (medications that decrease the level of cholesterol in the blood), since Erlotinib Tarbis may increase the risk of muscle-related problems associated with statin use, which, in rare cases, may lead to muscle degradation (rhabdomyolysis) causing kidney damage, consult your doctor.
• if you use contact lenses and/or have a history of eye problems such as very dry eyes, inflammation of the front part of the eye (cornea), or ulcers that involve the front part of the eye, inform your doctor.

immediately if you have persistent or severe diarrhea, nausea, loss of appetite, or vomiting, since your doctor may need to interrupt the administration of Erlotinib Tarbis and treat you in the hospital;

• if you have ever had liver problems. Erlotinib can cause severe liver problems and some cases have been fatal. Your doctor may perform blood tests while you are taking this medication to monitor if your liver is functioning correctly;
• if you have acute abdominal pain, blisters, or severe skin peeling. Your doctor may need to interrupt or discontinue your treatment;
• if you experience acute worsening or redness and pain in the eye, increased tearing, blurred vision, and/or sensitivity to light, please inform your doctor or nurse immediately, as you may need urgent treatment (see below Possible side effects).
