Aprepitant to prevent sickness

About aprepitant

Aprepitant is known as a neurokinin-receptor antagonist. It is prescribed alongside other medicines (desametasone and 5HT₃-receptor antagonists such as ondansetron) to help stop you from feeling or being sick after chemioterapia. It works by blocking the effect of a naturally produced chemical, called 'substance P'.

Some medicines are not suitable for people with certain conditions, and sometimes a medicine may only be used if extra care is taken. For these reasons, before you start taking aprepitant it is important that your doctor knows:

• Se sei incinta o stai allattando.

• Se hai problemi con il funzionamento del tuo fegato.

• Se hai mai avuto una reazione allergica a un medicinale.

• If you have a rare, inherited blood disorder called porphyria.

• If you are taking any other medicines, including any medicines you are taking which are available to buy without a prescription, as well as herbal and complementary medicines. Aprepitant interferes with a number of other medicines, including the 'pill' and the 'mini pill'.

• Before you start treatment, read the manufacturer's printed information leaflet from inside your pack. The manufacturer's leaflet will give you more information about aprepitant and a full list of side-effects which you may experience from taking it.

• Take aprepitant capsules exactly as your doctor tells you to. You will be asked to take one 125 mg capsule one hour before your chemo treatment starts, and then one 80 mg capsule each morning for the following two days.

• Swallow the capsules whole - it may help to take your doses with a drink of water. It is not important whether you take the capsules before or after food.

• If your child has been prescribed oral powder sachets, the dose will be prepared and given to your child by a doctor or nurse in hospital.

• If you forget to take a dose, contact your doctor for advice about what to do. Do not take two doses together to make up for a missed one.

• Even if you do not feel like eating or drinking, try to sip water regularly to prevent you from becoming lacking in fluid in the body (dehydrated).

• Rather than trying to eat three main meals a day, try eating small, simple but nourishing snacks, every few hours.

• If you are using hormonal contraception (this includes the 'pill' and the 'mini pill'), additional contraceptive precautions such as a condom will be required while you are on aprepitant, and for two months afterwards. If you need further advice about this, speak with your doctor or pharmacist.

• If you buy any medicines, check with a pharmacist that they are suitable to take with your other medicines. This is because many other medicines can interfere with aprepitant and therefore may not be recommended for you.

Along with their useful effects, most medicines can cause unwanted side-effects although not everyone experiences them. The table below contains some of the most common ones associated with aprepitant. You will find a full list in the manufacturer's information leaflet supplied with your medicine. The unwanted effects often improve as your body adjusts to the new medicine, but speak with your doctor or pharmacist if any of the following continue or become troublesome.

• Conservare in un luogo fresco e asciutto, lontano da fonti di calore e luce diretta.
