Estramustine for prostate cancer

About estramustine

Prostate cancer is a cancer which develops from cells in the prostate gland. It is the most common cancer in men in the UK. If the cancer spreads to other parts of your body, it is referred to as advanced prostate cancer. You may be offered anti-cancer medicine (chemotherapy) if you have advanced prostate cancer.

Estramustine is a chemotherapy medicine which reduces the number of cancer cells in your body by stopping cancer cells from multiplying. It also reduces the concentration of the male hormone testosterone. Cancer cells in other parts of your body need testosterone to grow and multiply, so this slows down the growth of the cancer which has spread.

Before taking estramustine

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 estramustine it is important that your doctor or pharmacist knows:

• If your partner is pregnant or breastfeeding.

• Wenn Sie unter hohem Blutdruck (Hypertonie) leiden.

• If you have any heart problems.

• If you have blood vessel disease, or if you have had any blood clot problems.

• Wenn Sie einen hohen Blutzuckerspiegel haben (Diabetes mellitus).

• If you have ever had a stomach or duodenal ulcer.

• If you have epilepsy or if you get migraine headaches.

• If you have been told you have high levels of calcium in your blood.

• If you have any liver or kidney problems.

• If you have problems with fluid retention, such as swollen feet or ankles.

• Wenn Sie eine Infektion haben oder sich unwohl fühlen.

• Wenn Sie eine seltene vererbte Blutkrankheit namens Porphyrie haben.

• Wenn Sie andere Arzneimittel einnehmen oder verwenden. Dazu gehören alle Arzneimittel, die Sie einnehmen und die rezeptfrei erhältlich sind, sowie pflanzliche und ergänzende Arzneimittel.

• Wenn Sie schon einmal eine allergische Reaktion auf ein Arzneimittel hatten.

How to take estramustine

• Estramustine will be prescribed for you by a doctor who is a specialist and experienced in treating your condition. Take the capsules exactly as your doctor tells you to. It is usual to be prescribed 4-6 capsules to take over the course of a day to begin with, although this may be adjusted as your treatment continues. Doses may range between 1-10 capsules taken daily. If you are unsure about how or when to take the capsules, or if you have any other concerns, you should contact your doctor or hospital clinic for advice.

• You should take the capsules when your stomach is empty, which means taking them one hour before eating food, or waiting until two hours afterwards. This is because food prevents estramustine from being absorbed by your body, which means the medicine is much less effective for you.

• Swallow the capsules with a drink of water. Do not open, crush or chew them.

• Before you start this treatment, read any printed information you have been given by your doctor, and the leaflet from inside your pack. The leaflet will give you more information about estramustine and a full list of side-effects which you may experience from taking it.

• If you are sick shortly after taking a dose, or if you forget a dose, contact your doctor or clinic for advice on what to do. You will be told whether to take the dose again, or wait until the next dose is due.

• Do not drink any milk, or take any medicines containing calcium, magnesium or aluminium at the same time as you take estramustine. Some antacid and laxative preparations contain these, so ask your pharmacist for advice before you buy or take any 'over-the-counter' medicines.

Das Beste aus Ihrer Behandlung herausholen

• You must try to keep your regular appointments with your doctor or hospital. This is so your doctor can check on your progress. You will need to have regular check-ups during your treatment, to monitor for unwanted side-effects.

• Estramustine may lower the number of white cells in your blood, increasing the chance of you getting an infection. If possible, avoid people who you know are ill, and let your doctor know if you feel you are getting an infection.

• While you are taking estramustine do not have any immunisations (vaccinations) without talking to your doctor first. Estramustine lowers your body's resistance so there is a chance that you may get an infection from some vaccines.

• Wenn Sie sich einer Operation oder einer zahnärztlichen Behandlung unterziehen müssen, teilen Sie der behandelnden Person mit, welche Arzneimittel Sie einnehmen.

• Although there is a risk of reduced fertility with estramustine treatment, it is important that you do not father a child while you are being treated. Make sure you have discussed these issues with your doctor if you are sexually active.
