Other medicines and IRESSA

Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines.

In particular, tell your doctor or pharmacist if you are taking any of the following medicines:

• Phenytoin or carbamazepine (for epilepsy).
• Rifampicin (for tuberculosis).
• Itraconazole (for fungal infections).
• Barbiturates (a type of medicine used for sleeping problems).
• Herbal remedies containing St John’s wort (Hypericum perforatum, used for depression and anxiety).
• Proton-pump inhibitors, H₂-antagonists and antacids (for ulcers, indigestion, heartburn and to reduce acids in the stomach).

These medicines may affect the way IRESSA works.

• Warfarin (a so-called oral anticoagulant, to prevent blood clots). If you are taking a medicine containing this active substance, your doctor may need to do blood tests more often.

If any of the above applies to you, or if you are not sure, check with your doctor or pharmacist before taking IRESSA.

Pregnancy, breast-feeding and fertility

Talk to your doctor before taking this medicine if you are pregnant, may become pregnant or are breast-feeding.

It is recommended that you avoid becoming pregnant during treatment with IRESSA because IRESSA could harm your baby.

If you take more IRESSA than you should

If you have taken more tablets than you should, talk to a doctor or pharmacist straight away.

If you forget to take IRESSA

What to do if you forget to take a tablet depends on how long it is until your next dose.

• If it is 12 hours or more until your next dose: take the missed tablet as soon as you remember. Then take the next dose as usual.
• If it is less than 12 hours until your next dose: skip the missed tablet. Then take the next tablet at the usual time.

Do not take a double dose (two tablets at the same time) to make up for a forgotten dose.

Tell your doctor immediately if you notice any of the following side effects-you may need urgent medical treatment:

• Allergic reaction (common), particularly if symptoms include swollen face, lips, tongue or throat, difficulty to swallow, hives, nettle rash and difficulty breathing.
• Serious breathlessness, or sudden worsening breathlessness, possibly with a cough or fever. This may mean that you have an inflammation of the lungs called ‘interstitial lung disease’. This may affect about 1 in 100 patients taking IRESSA and can be life-threatening.
• Severe skin reactions (rare) affecting large areas of your body. The signs may include redness, pain, ulcers, blisters, and shedding of the skin. The lips, nose, eyes and genitals may also be affected.
• Dehydration (common) caused by long term or severe diarrhoea, vomiting (being sick), nausea (feeling sick) or loss of appetite.
• Eye problems (uncommon), such as pain, redness, watery eyes, light sensitivity, changes in vision or ingrowing eyelashes. This may mean that you have an ulcer on the surface of the eye (cornea).
