What AVONEX is used for

AVONEX is used for the treatment of relapsing forms of Multiple Sclerosis (MS). AVONEX treatment has been shown to:
Slow the progression of disability
Reduce the number of relapses
Delay the onset of definite MS after an illness suggesting MS
The cause of MS is not yet known. MS affects the brain and spinal cord. In MS, the body's immune system reacts against its own myelin (the 'insulation' surrounding nerve fibres). In relapsing forms of MS, people have 'exacerbations' from time to time (e.g. blurred vision, weakness in the legs or arms, or loss of control of bowel or bladder function). They are followed by periods of recovery. Recovery may be complete or incomplete. If it is incomplete there is 'progression of disability'.
AVONEX belongs to a group of medicines called interferons. Interferons exist naturally in the body to help fight viral infections and regulate the body's immunity.
Although the exact mechanism of interferons in MS is unknown, it is thought that AVONEX works by decreasing the unwanted immune reaction against myelin.
There is no information on the use of this medicine in those below 12 years of age.
Ask your doctor if you have any questions about why AVONEX has been prescribed for you.
Your doctor may have prescribed AVONEX for another reason.
AVONEX is available only with a doctor's prescription.
Use only for the person for whom it has been prescribed.

Before you use AVONEX

Do not use AVONEX if you have severe depression, and particularly if you are having suicidal thoughts.
Depression is common in people with MS and in those using medicines like AVONEX.
Tell your doctor if you are feeling depressed, or having suicidal thoughts.
Your doctor can help you decide whether you should use AVONEX or not.
Do not use AVONEX if you are pregnant or trying to become pregnant.
It may affect the development of your baby if you use it during pregnancy.
If you wish to become pregnant and are having treatment with AVONEX, please discuss this with your doctor.

In particular, tell your doctor if you are taking any medicine:
Used to treat epilepsy (prevent fits)

How to use AVONEX

Follow all directions given to you by your doctor, MS education nurse or pharmacist carefully.
They may differ from the information contained in this leaflet.

How much to use

The usual full dose of AVONEX is 30 micrograms once a week, given as a 0.5 mL injection.
Starting AVONEX
If you are new to AVONEX, your doctor or MS nurse may advise you to gradually increase your dose to minimise potential side effects of AVONEX, such as flu-like symptoms, before taking the full dose.

How to use it

Starting AVONEX
Your doctor or MS nurse may provide you with an AVOSTARTCLIP titration kit to help gradually increase your dose of AVONEX during the first 3 weeks of treatment. The kit contains 3 different coloured clips (labelled week 1, 2 and 3). Each clip is designed for use with AVONEX solution for injection and attaches to the pre-filled syringe. The clip enables either a quarter, a half or a three-quarter dose of AVONEX to be injected during your first 3 weeks of treatment.
Each AVOSTARTCLIP should be used once and then discarded along with any remaining AVONEX.
For further details on use, please follow the instructions provided with the AVOSTARTCLIP titration kit.
AVONEX is given by injection into muscle, usually in the thigh or upper arm. The buttock is not a suitable site for injection. Your doctor will recommend an injection site suitable for you.
How to inject
Many people with MS learn to give themselves the injection or have it given by a carer.
Self-injection needs to be taught and practised. It is important that a qualified health care professional supervises your first injection.
Your doctor may teach you to self-inject or arrange for an MS education nurse to do so.
Talk to your doctor or the MS Society or telephone the MS ALLIANCE Helpline (1800 286 639 in Australia or 0800 286 639 in NZ) for more information.
After being taught to self-inject, you should refer to the leaflet in the pack for step-by-step instructions about how to prepare and inject AVONEX. Patient support kits are available by telephoning the MS Alliance on 1800 286 639 in Australia or 0800 286 639 in NZ.
AVONEX Solution for Injection is pre-mixed ready for you to use and should be stored in a refrigerator. It is recommended that you remove it from the refrigerator about half-an-hour before you want to use it. This allows the temperature of the medicine to approach room temperature.
Do not use heat sources (heater or hot water) to warm it.
Heating can damage this medicine.
Always inspect AVONEX Solution before use.
The medicine should be clear and colourless or slightly yellow.
Do not inject if the solution is discoloured or cloudy or contains particles.
Talk to your specialist, doctor or pharmacist, contact the MS Society, or telephone the MS Alliance on 1800 286 639 in Australia or 0800 286 639 in NZ, if you have any questions about how to use AVONEX.

How long to use it

The positive effects of AVONEX are not seen immediately. They occur with long-term treatment. It is important to continue treatment with AVONEX unless your doctor tells you to stop.

If you forget to use it

If it is less than 2 days before your next injection, skip the dose you missed and have your next injection when you are meant to.
Otherwise, have it as soon as you remember and then resume your regular weekly dosing schedule.
Do not use a double dose to make up for the dose that you missed.
This may increase the chance of you getting an unwanted side effect.
If you are not sure what to do, ask your doctor or pharmacist, contact the MS Society in your State, or telephone the MS ALLIANCE Helpline (1800 286 639 in Australia or 0800 286 639 in NZ).
If you have trouble remembering your injections, ask your pharmacist or MS education nurse for some hints.
It is important not to miss injections as this can affect the success of your treatment.

If you use too much (overdose)

Immediately telephone the Australian Poisons Information Centre (telephone 13 11 26), or the New Zealand National Poisons Information Centre (telephone 0800 POISON or 0800 764 766), if you think you or anyone else may have used too much AVONEX.
Do this even if there are no signs of discomfort or poisoning. You may need urgent medical attention.

While you are using AVONEX

Things you must do:

If you become pregnant while on treatment with AVONEX, immediately tell your doctor.
You and your doctor will decide what is best for you and your baby. It is likely that your doctor will recommend you stop using AVONEX during your pregnancy.
If you are a female of childbearing age and are sexually active, you should use birth control during treatment with AVONEX.
Always talk to your doctor or pharmacist before taking any other medicine while you are using AVONEX.
If he or she recommends that you take a medication to reduce symptoms of pain and inflammation, follow their advice carefully. Do not take more than the recommended dose.
Tell any other doctors, dentists and pharmacists who treat you that you are using this medicine.
If you are about to have any blood tests, tell your doctor that you are using AVONEX.
Keep all your doctor's appointments so that your progress can be checked.
Your doctor may do blood tests before you start treatment and from time to time to monitor your progress and prevent unwanted side effects.

Things you must not do

Do not give AVONEX to anyone else, even if they appear to have the same condition as you.
Do not stop using AVONEX or change the dosage, without checking with your doctor.

Things to be careful of

Be careful drinking alcohol while you are on treatment with AVONEX.
Rarely, people treated with interferons including AVONEX, have experienced serious liver problems. It is not known whether this risk is increased by alcohol but it is possible.
Talk to your doctor or pharmacist about this if you want more information.

Side effects

Tell your doctor or pharmacist as soon as possible if you do not feel well while using AVONEX.
AVONEX helps most people with MS but it may have unwanted effects in a few people. All medicines have side effects. Sometimes they are serious, most of the time they are not. You may need medical attention if you get some side effects.
Do not be alarmed by the following lists of side effects.
You may not experience any of them.
Ask your doctor, MS nurse or pharmacist to answer any questions you may have.
The most common side effect is to feel 'flu-like' symptoms, e.g. mainly tiredness, muscle aches, shivering and fever. Your doctor or MS nurse may advise you to gradually increase your dose of AVONEX during the first 3 weeks of treatment to help reduce these symptoms. These side effects generally occur less often as therapy continues.
To help further reduce these symptoms, your doctor may advise you to take a medication (e.g., paracetamol, ibuprofen) to reduce fever, pain and inflammation before your injection and for up to one day afterwards.
Tell your doctor, nurse or pharmacist if you notice any of the following and they worry you:
Headache
Nausea, vomiting or diarrhoea
Abdominal (stomach) pain
Chest pain
Migraine
Joint or muscle pain, stiffness or spasms
Dizziness, feeling faint
Sleeplessness
Soreness, redness or bruising at the injection site
Loss of appetite
Runny nose, coughing
Increased sweating (sometimes at night) or flushing
Rash
Strong and frequent urge to urinate, with pain or burning sensation when urinating
Reduced sensitivity to touch
The above list includes the more common side effects of AVONEX. These effects might also be related to your general health or the MS process, or to a combination of these.
Tell your doctor as soon as possible if you notice any of the following:
Unusual confusion, anxiety, worsening of depression, severe mood swings or thoughts of suicide
Seizures, fits, convulsions or fainting
Yellowing of the skin and eyes (also called jaundice)
Breathlessness, persistent coughing, swelling in hands, feet or lower arms and legs, or palpitations
Unusual bleeding or bruising
Hives or itchy skin
The above list includes serious side effects that may require medical attention. Serious side effects are rare.
If any of the following happen, tell your doctor immediately, or go to Accident and Emergency at your nearest hospital:
Swelling of the face, lips, mouth or throat which may cause difficulty in swallowing or breathing
These could be symptoms of an allergic reaction.
Discharge from the injection site or pain, redness or swelling that does not go away
The above list includes very serious side effects. You may need urgent medical attention or hospitalisation. These side effects are very rare.
Tell your doctor or pharmacist if you notice anything else that is making you feel unwell.
Other side effects not listed above may occur in some people.
Some side effects can only be found when your doctor does tests from time to time to check your progress. They include changes in thyroid function, liver function or blood counts.
