Binit Film-Coated Tablets

BINIT contains the active ingredient erlotinib. BINIT 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. BINIT is indicated for adults. BINIT can be prescribed for you if you have non-small cell lung cancer or adenocarcinoma of your lung at an advanced stage. It can be prescribed as initial therapy of your disease if your cancer cells have specific EFGR mutations. It can also be prescribed if your disease remains largely unchanged after initial chemotherapy, or if previous chemotherapy has not helped to stop your disease. BINIT can also be prescribed to you in combination with another treatment called gemcitabine if you have cancer of the pancreas at a metastatic stage.

Do not take BINIT if you are hypersensitive (allergic) to erlotinib or to any of the other ingredients of BINIT listed in section 6 of this leaflet.

Warnings and precautions

Take special care with BINIT:

• If you are taking other medicines that may increase or decrease the amount of BINIT in your blood or influence its effect. See ‘Other medicines and BINIT’.
• If you use contact lenses and/or have a history of eye problems, such as severe dry eyes, inflammation or ulcers in your eye.

You should tell your doctor if you have:

• Sudden difficulty in breathing associated with cough or fever. Your doctor may need to treat you with other medicines and interrupt your BINIT treatment with BINIT.
• Diarrhoea. Your doctor may need to treat you with anti-diarrhoeal medicines.
• Severe, bloody or persistent diarrhoea, nausea, loss of appetite or vomiting. You should immediately tell your doctor, as he/she may need to interrupt or stop your treatment with BINIT and may need to treat you in the hospital.
• Severe pain in the stomach area or a history of diverticular disease or peptic ulceration.
• Severe blistering or peeling of the skin. Your doctor may need to interrupt or stop your treatment with BINIT.
• Acute or worsening eye problems, such as redness and pain in the eye, increased watering of your eye, blurred vision or sensitivity to light. Your doctor may need to interrupt or stop your treatment with BINIT.

You should tell your doctor if you are taking statin medicine and experience unexplained muscle pain, tenderness, weakness or cramps while taking BINIT. Your doctor may need to interrupt your treatment with BINIT. See ‘Other medicines and BINIT’.

Treatment with BINIT is not recommended if you have severe liver disease or severe kidney disease.

Your doctor will treat you with caution if you have a disorder like Gilbert’s syndrome, which can affect your liver and enzymes in your body, causing jaundice (yellowing of the skin and whites of the eyes).

You are advised to stop smoking if you are treated with BINIT, as smoking considerably decreases the amount of BINIT available in your blood.

You are advised to wear protective clothing and/or use sunscreen when you are exposed to the sun during your treatment with BINIT.

Children and adolescents

BINIT has not been studied in patients under the age of 18 years. The treatment with BINIT is not recommended in children and adolescents.

Other medicines and BINIT

Always tell your health care provider if you are taking any other medicine. (This includes all complementary or traditional medicines.) Tell your doctor or pharmacist before you take BINIT if you are taking other medicines that may increase or decrease the amount of BINIT in your blood or influence its effect, such as:

• Ciprofloxacin, erythromycin or clarithromycin (used to treat certain bacterial infections).
• Fluvoxamine (used to treat depression).
• Ketoconazole, itraconazole or voriconazole (used to treat fungal infections).
• Protease inhibitors (used to treat human immunodeficiency virus (HIV) infection).
• Rifampicin (used to treat tuberculosis (TB)).
• Phenytoin or carbamazepine (used to treat seizures (fits)).
• Barbiturates (used to treat insomnia or anxiety).
• St John’s Wort (herbal medicine).
• Omeprazole or ranitidine (used to treat acid reflux).

In some cases, these medicines may reduce the efficacy or increase the side effects of BINIT and your doctor may need to adjust your treatment.

Tell your doctor or pharmacist before you take BINIT if you are taking:

• Anticoagulants, such as warfarin (used to prevent blood clots). BINIT may increase your risk for bleeding and your doctor may need to regularly monitor you with blood tests.
• Statins (a group of medicine used to lower the cholesterol (fat) in your blood). BINIT may increase the risk of statin related muscle problems, which on rare occasions can lead to serious muscle breakdown (rhabdomyolysis) resulting in kidney damage.
• Ciclosporin (used to treat psoriasis, rheumatoid arthritis or during organ transplants).
• Verapamil (used to treat high blood pressure or heart problems).
• Capecitabine (used to treat cancer).

Avoid pregnancy while being treated with BINIT. If you can become pregnant, use adequate contraception during treatment, and for at least 2 weeks after taking the last tablet. If you become pregnant while on treatment with BINIT, immediately inform your doctor who will decide if treatment should be continued. Do not breastfeed your baby while taking BINIT.
