1. Why am I using PLEGRIDY?

PLEGRIDY contains the active ingredient peginterferon beta-1a (rch). PLEGRIDY belongs to a group of medicines called interferons.

What PLEGRIDY is used for

PLEGRIDY is a prescription medicine used to treat people with relapsing forms of Multiple Sclerosis (MS). It is not known if PLEGRIDY is safe and effective in people under 18 or over 65 years of age.

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’.

PLEGRIDY belongs to a group of medicines called interferons. The active substance in PLEGRIDY is peginterferon beta-1a. Peginterferon beta-1a is a long-acting form of interferon. Interferons exist naturally in the body to help fight viral infections and regulate the body’s immunity.

Although the exact mechanism of action of interferons in MS is unknown, it is thought that PLEGRIDY works by decreasing the unwanted immune reaction against myelin.

2. What should I know before I use PLEGRIDY?

Some medicines may interfere with PLEGRIDY and affect how it works.

  • medicines to treat epilepsy
  • medicines to treat depression

Check with your doctor or pharmacist if you are not sure about what medicines, vitamins or supplements you are taking and if these affect PLEGRIDY.

4. How do I use PLEGRIDY?

Follow all directions given to you by your doctor, MS nurse or pharmacist carefully.

They may differ from the information contained in this leaflet.

How much to use

Starting PLEGRIDY

If you are new to PLEGRIDY your doctor or MS nurse may advise you to gradually increase your dose so that you can adjust to the effects of PLEGRIDY before taking the full dose. You will be provided with a Titration Pack containing your first two injections. For further details on use, please follow the instructions provided with the Titration Pack.

The recommended starting dose is a single injection of PLEGRIDY 63 micrograms, followed by a single injection of PLEGRIDY 94 micrograms two weeks later.

You will be provided with an Administration Dose Pack containing your next injections.

The recommended third dose is a single injection of PLEGRIDY 125 micrograms (full dose), two weeks after the second dose.

Full doses of PLEGRIDY 125 micrograms are then recommended every 14 days (two weeks).

Use the record table printed on the inside lid of the Pack to keep a track of your injection dates.

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

When to use PLEGRIDY

PLEGRIDY is only to be injected once every 14 days (two weeks).

PLEGRIDY is injected under the skin (subcutaneously). Try to use PLEGRIDY at the same time on the same day every time you inject.

How to inject PLEGRIDY Pen

Many people with MS learn to give themselves the injection or have it given by a carer.

Self-injection needs to be taught and practiced. 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 nurse to do so.

Keep referring to the leaflet for detailed instructions on how to use PLEGRIDY.

You can obtain more information from your doctor, pharmacist or the MS Society in your State, or by telephoning 1800 852 289 in Australia or 0800 852 289 in NZ.

If you forget to use PLEGRIDY

PLEGRIDY should be used regularly at the same time every 14 days. If you miss your dose at the usual time, inject as soon as you remember and then resume your regular dosing schedule. However, never inject more than once in a 7-day period.

Do not take a double dose to make up for the dose 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.

If you have trouble remembering to take your medicine, ask your pharmacist or MS nurse for some hints.

If you use too much PLEGRIDY

If you think that you have used too much PLEGRIDY, you may need urgent medical attention.

You should immediately:

  • phone the Poisons Information Centre
    (by calling 13 11 26 in Australia, or 0800 POISON or 0800 764 766 in New-Zealand), or
  • contact your doctor, or
  • go to the Emergency Department at your nearest hospital.

You should do this even if there are no signs of discomfort or poisoning.

5. What should I know while using PLEGRIDY?

Things you should do

Call your doctor straight away if you:

  • If you become pregnant while on treatment with PLEGRIDY, immediately tell your doctor.
    If you are a female of childbearing age and are sexually active, you should use birth control during treatment with PLEGRIDY.
  • If you have new or worsening depression or suicidal thoughts, immediately tell your doctor:
    This could include feeling hopeless or bad about yourself, thoughts of hurting yourself or suicide, irritability (getting upset easily), nervousness, or new or worsening anxiety.

Always talk to your doctor or pharmacist before taking any other medicine while you are using PLEGRIDY.

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.

Remind any doctor, dentist or pharmacist you visit that you are using PLEGRIDY.

If you are about to have any blood tests, tell your doctor that you are using PLEGRIDY.

  • Confusion
Call your doctor straight away, or go straight to the Emergency Department at your nearest hospital if you notice any of these serious side effects.

Flu-like symptoms

The most common side effect is to feel ‘flu-like’ symptoms, e.g. headache, tiredness, muscle aches, joint pain, shivering and fever. Your doctor or MS nurse may advise you to gradually increase your dose of PLEGRIDY during the first month of treatment to help reduce these symptoms. These side effects generally occur less often as therapy continues.

Three simple ways to help reduce the impact of flu-like symptoms:

  1. Consider the timing of your PLEGRIDY injection. The start and end of flu-like symptoms are different for every patient. On average, flu-like symptoms begin approximately 10 hours after injection and last for about 17 hours.
  2. Take paracetamol or ibuprofen half an hour before your PLEGRIDY injection. Speak to your doctor or pharmacist about how much to take and how long to take it.
  3. If you have a fever, drink plenty of water to keep you hydrated.

Injection site reactions

You may get reactions around the place you inject. These usually get less over time. Reactions such as redness, itching or pain are very common. Swelling, bruising, warmth or rash at the injection site is common.

To reduce injection site reactions, read and follow the advice given in the “Instructions for Use” at the end of the pack insert.

Tell your doctor or pharmacist if you notice anything else that may be making you feel unwell.

Some side effects (such as decreased blood cell counts, or changed liver function) can only be found when your doctor does tests from time to time to check your progress.

Other side effects not listed here may occur in some people.

Reporting side effects

After you have received medical advice for any side effects you experience, you can report side effects to the Therapeutic Goods Administration online at www.tga.gov.au/reporting-problems. By reporting side effects, you can help provide more information on the safety of this medicine.

Always make sure you speak to your doctor or pharmacist before you decide to stop taking any of your medicines.
