Buserelin for men

About buserelin for men

Although in many cases prostate cancer is slow-growing, in some men it can be more aggressive and spread to other parts of the body. When this happens, there can be a benefit from using a hormone treatment, such as buserelin, which slows the progress of the cancer.

Prostate cancer cells need the male hormone testosterone to grow. Buserelin works by reducing the production of testosterone and this helps to stop the growth of the cancer cells.

Buserelin is also used in some disorders which affect women. There is a separate medicine leaflet called Buserelin for women which gives more information about this.

Before using buserelin

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 using buserelin it is important that your doctor knows:

• If you have low moods or are depressed.

• If you have high blood pressure (hypertension).

• If you have diabetes (diabetes mellitus).

• If you have a bone disease such as osteoporosis.

• If you are taking or using any other medicines. This includes any medicines you are taking which are available to buy without a prescription, as well as herbal and complementary medicines.

• If you have ever had an allergic reaction to a medicine.

How to use buserelin

• Before you start the treatment, read the manufacturer's printed information leaflet from inside the pack. It will give you more information about buserelin and will provide you with a full list of the side-effects which you could experience.

• When you start buserelin, you will be given injections every eight hours for the first seven days. For convenience, these injections are likely to be given to you while you are in hospital. On the next day, you will be given a nasal spray to use. You must follow the instructions given to you by your doctor for using the spray, but it is usually recommended that you use one spray into each nostril six times each day as follows:

• 1st dose before your breakfast.

• 2nd dose after your breakfast.

• 3rd dose before your midday meal.

• 4th dose after your midday meal.

• 5th dose before your evening meal.

• 6th dose after your evening meal.

• Each time you open a new bottle, you will need to attach the nebuliser to the bottle of solution and then 'prime' the spray. You do this by pumping the spray about six or seven times until you see a fine spray produced. Priming fills the nebuliser and tests that the spray is working correctly.

• It is important that you use this medicine regularly and space the doses out evenly through the day. If you forget to take a dose at your usual time, take it as soon as you remember. If it is almost time for your next dose then skip the forgotten dose and take your next dose when it is due. Do not take two doses together to make up for a forgotten dose.

• About 1 in 10 men notice that their symptoms (usually pain) become worse for a short while when they first start treatment with buserelin. Your doctor is likely to give you some tablets to take during the first few weeks to help prevent this. If you do experience any increase in pain, this will settle again after a couple of weeks.

• Please keep your appointments with your doctor so that your progress can be monitored. Your doctor will want you to have regular blood tests to check your hormone levels.

• Even if you get a cold or your nose feels blocked, you should continue to use the spray as it will still work. If you are using any other nasal sprays (such as decongestants), you should use buserelin spray first, then wait at least 30 minutes after using buserelin before using the other nasal spray.

• Buserelin can affect your blood sugar levels. If you have diabetes you may need to check your blood glucose more frequently. Your doctor will advise you about this.

Can buserelin cause problems?

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 buserelin. 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.

If you experience any other symptoms which you think may be due to buserelin, please speak with your doctor or pharmacist for further advice.

How to store buserelin

• Keep all medicines out of the reach and sight of children.

• Store in a cool, dry place, away from direct heat and light.

• Each bottle of nasal spray contains one week of treatment. Even if there is some solution left after using the spray for a week, please do not use it. Instead, open a fresh bottle.
