Due to regulatory changes, the content of the following Patient Information Leaflet may vary from the one found in your medicine pack. Please compare the 'Leaflet prepared/revised date' towards the end of the leaflet to establish if there have been any changes.
If you have any doubts or queries about your medication, please contact your doctor or pharmacist.
1. What Nebido is and what it is used for
Nebido contains testosterone, a male hormone, as the active ingredient. Nebido is injected into a muscle in your body. There it can be stored and gradually released over a period of time.
Nebido is used in adult men for testosterone replacement to treat various health problems caused by a lack of testosterone (male hypogonadism). These should be confirmed by two separate blood testosterone measurements and also include clinical symptoms such as:
- low sex drive
- depressive moods
- bone loss caused by low hormone levels
2. What you need to know before you are given Nebido
Do NOT use Nebido
- if you are allergic to testosterone undecanoate or any of the other ingredients of this medicine (listed in section 6)
- if you have ever had androgen-dependent cancer or suspected cancer of the prostate or of the breast
- if you have or have ever had a liver tumour
Nebido is not intended for use in women.
Nebido is not for use in children and adolescents. There is no data available on the use of Nebido in males under 18 years of age.
Warnings and precautions
Talk to your doctor before using Nebido if you have or have ever had:
- heart, kidney or liver problems
- temporary interruptions in your breathing during sleep (apnoea), as these may get worse
- cancer, as the level of calcium in your blood may need to be tested regularly
- blood clotting problems
If you are suffering from severe heart, liver or kidney disease, treatment with Nebido may cause severe complications in the form of water retention in your body sometimes
accompanied by (congestive) heart failure.
The following blood checks should be carried out by your doctor before and during the treatment: testosterone blood level, full blood count.
Tell your doctor if you have high blood pressure or if you are treated for high blood pressure, as testosterone may cause a rise in blood pressure.
If your liver is not working
No formal studies have been performed in patients with liver impairment. You will not be prescribed Nebido if you have ever had a liver tumour (see “Do not use Nebido”).
Elderly patients (65 years or older)
There is no need for your doctor to adjust the dose if you are over 65 (see “Medical examination/follow-up”).
Muscle building and drug tests
Nebido is not suitable for building muscles in healthy individuals or for increasing physical strength.
Nebido might lead to positive results in drug tests.
Male hormones may increase the growth of prostate cancer and enlarged prostate glands (benign prostatic hypertrophy). Before your doctor injects Nebido, he/she will examine you to
check that you do not have prostate cancer.
Your doctor will regularly examine your prostate and breast, especially if you are elderly. He/she will also take regular blood samples.
Following the use of hormonal substances such as androgen compounds, cases of benign (non-cancerous) and malignant (cancerous) liver tumours have been observed to occur.
Other medicines and Nebido
Tell your doctor or pharmacist if you are using or have recently used or might use any other medicines, including medicines obtained without a prescription. The doctor may need to
adjust the dose if you are using any of the following:
- the hormone ACTH or corticosteroids (used to treat various conditions such as rheumatism, arthritis, allergic conditions and asthma): Nebido may increase the risk of water retention, especially if your heart and liver are not working properly
- tablets that thin your blood (anticoagulants)
If you are diabetic, it may be necessary to adjust your insulin.
Nebido may also affect the results of some laboratory tests (e.g. thyroid gland). Tell your doctor or the laboratory staff that you are using Nebido.
Pregnancy, breast-feeding and fertility
Nebido is not for use in women and must not be used in pregnant or breast-feeding women.
Testosterone replacement therapy may reversibly reduce spermatogenesis.
Driving and using machines
Nebido has no effect on your ability to drive or use machines.
3. How to use Nebido
Your doctor will inject Nebido (1 ampoule / vial) very slowly into a muscle. He/she will give you the injections every 10 to 14 weeks. This is enough to maintain sufficient testosterone
levels without leading to a build-up of testosterone in the blood.
Nebido is strictly for intramuscular injection. Special care will be taken to avoid injection into a blood vessel (see “Notes on handling the OPC (One-Point-Cut) ampoule”).
Start of treatment
Your doctor will measure your blood testosterone levels before starting treatment and during the early stages of treatment. Your doctor may give you the second injection after only six
weeks in order to quickly reach the necessary testosterone level. This will depend on your symptoms and testosterone levels.
Maintaining your Nebido levels during treatment
The injection interval should always be within the recommended range of 10 to 14 weeks. Your doctor will measure your testosterone levels regularly at the end of an injection interval
to make sure it is at the right level. If the level is too low, your doctor may decide to give you injections more often. If your testosterone levels are high, your doctor may decide to give you
injections less often. Do not miss your injection appointments. Otherwise, your optimum level of testosterone will not be maintained.
If you think that the effect of Nebido is too strong or too weak, talk to your doctor.
If you used more Nebido than you should
Symptoms of having too much Nebido include:
- weight gain
- long-lasting or frequent erections
Tell your doctor, if you have any of these. Your doctor will inject it less often or will stop treatment.
4. Possible side effects
Like all medicines, this medicine can cause side effects, although not everybody gets them.
The most common side effects are acne and pain where the injection is given.
Common side effects (may affect up to 1 in 10 patients):
- abnormally high levels of red blood cells
- weight gain
- hot flushes
- enlarged prostate and associated problems
- various reactions where the injection was given (e.g. pain, bruising, or irritation)
Uncommon side effects (may affect up to 1 in 100 patients):
- allergic reaction
- increased appetite, changes in blood test results (e.g. increased blood sugars or fats)
- depression, emotional disorder, insomnia, restlessness, aggression, or irritability
- headache, migraine, or tremor
- cardiovascular disorder, high blood pressure, or dizziness
- bronchitis, sinusitis, cough, shortness of breath, snoring, or voice problems
- diarrhoea, or nausea
- changes in liver test results
- hair loss, or various skin reactions (e.g. itching, reddening, or dry skin)
- joint pain, pain in limbs, muscle problems (e.g. spasm, pain or stiffness), or an increase in the blood substance creatine phosphokinase
- urinary tract disorders (e.g. decreased flow of urine, urinary retention, urge to pass urine at night)
- prostatic disorders (e.g. prostatic intraepithelial neoplasia, or hardening or inflammation of the prostate), changes in sexual appetite, painful testicles, painful, hardened or enlarged breasts, or increased levels of male and female hormones
- tiredness, general feeling of weakness, excessive sweating, or night sweats
The oily liquid Nebido may reach the lungs (pulmonary microembolism of oily solutions) which can in rare cases lead to signs and symptoms such as cough, shortness of breath,
feeling generally unwell, excessive sweating, chest pain, dizziness, “pins and needles”, or fainting. These reactions may occur during or immediately after the injection and are reversible.
Suspected anaphylactic reactions after Nebido injection have been reported.
In addition to the side effects listed above the following have been reported following treatment with preparations containing testosterone: nervousness, hostility, brief interruptions
in breathing during sleep, various skin reactions including dandruff and oily skin, more frequent erections, and very rare cases of yellowing of the skin and eyes (jaundice).
Treatment with high doses of testosterone preparations commonly stops or reduces sperm production, although this returns to normal after treatment ceases. Testosterone replacement therapy of poorly functioning testicles (hypogonadism) can in rare cases cause persistent, painful erections (priapism). High-dosed or long-term administration of testosterone occasionally increases the occurrences of water retention and oedema (swelling due to fluid retention).
For testosterone products in general a common risk of increased red blood cell count, haematocrit (percentage of red blood cells in blood) and haemoglobin (the component of red
blood cells that carries oxygen), were observed by periodic blood tests.
