What NeuroBloc is and What It is Used For

NeuroBloc injection works by reducing or stopping muscle contractions. It contains the active ingredient ‘Botulinum Toxin Type B’.

NeuroBloc is used to treat an illness called cervical dystonia (torticollis). This is where you have contractions of your neck or shoulder muscles that you cannot control.

What You Need to Know Before You Use NeuroBloc

Do Not Use NeuroBloc:

  • if you are allergic to Botulinum Toxin Type B or any of the other ingredients of NeuroBloc (listed in Contents of the Pack and Other Information)
  • if you have other problems with your nerves or muscles, such as amyotrophic lateral sclerosis (Lou Gehrig's disease), peripheral neuropathy, myasthenia gravis or Lambert-Eaton syndrome (muscle weakness or numbness or pain)
  • if you have been experiencing shortness of breath or difficulty swallowing

You must not be given NeuroBloc if any of the above applies to you. If you are not sure talk to your doctor or pharmacist.

Warnings and Precautions

Talk to your doctor or pharmacist before using NeuroBloc:

  • if you have a bleeding problem such as haemophilia
  • if you have lung problems
  • if you have difficulty swallowing. This is because swallowing problems could make you breathe food or liquids into your lungs, which could then cause very serious pneumonia

General precaution

NeuroBloc has been approved for the treatment of cervical dystonia only and should not be used to treat anything else. The safety of NeuroBloc when used to treat other conditions is not known: some side effects may be fatal.

Children and Adolescents

NeuroBloc is not to be used in children aged 0-18 years.

Other Medicines and NeuroBloc

Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines. This is because NeuroBloc can affect the way some medicines work and other medicines can also affect the way NeuroBloc works.

In particular, tell your doctor or pharmacist if you are taking any of the following medicines:

  • aminoglycoside antibiotics for an infection
  • medicines to stop blood clotting, such as warfarin

If you are not sure if any of the above applies to you, talk to your doctor or pharmacist before you are given NeuroBloc.

Before having an operation

If you are going to have an operation, please tell your doctor that you have been given NeuroBloc. This is because NeuroBloc can affect the medicines you may be given before a general anaesthetic.

Pregnancy, Breast-feeding and Fertility

  • you will not normally be given NeuroBloc if you are pregnant or breast-feeding. This is because it is not known how NeuroBloc affects patients who are pregnant and it is not known if NeuroBloc passes into a nursing mother’s breast milk
  • if you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine

Driving and Using Machines

You may have muscle weakness or eye problems such as blurred vision or eyelid drooping after being given NeuroBloc. If this happens, do not drive or use any tools or machines.

NeuroBloc contains less than 1 mmol sodium (23 mg) per 10,000 units of NeuroBloc. This means it is essentially “sodium free”.

How to Use NeuroBloc

NeuroBloc will be given to you by a doctor with specialist experience in the treatment of cervical dystonia and in the use of botulinum toxins.

How Much Will be Given

  • your doctor will decide how much NeuroBloc to give you
  • the usual dose is 10,000 units, however, it can be higher or lower
  • if you have had NeuroBloc injections before, your doctor will take into account how well it worked the other times

How NeuroBloc is Given

  • NeuroBloc will be injected into your neck or shoulder muscles, depending on which ones are causing the problem
  • your doctor may inject part of the dose into different places in your muscles

Having More Injections of NeuroBloc

  • the effects of NeuroBloc will usually last about 12 to 16 weeks
  • your doctor will decide if you need another injection and how much to give you

If you think that the effect of NeuroBloc is too strong or too weak, talk to your doctor.

If You are Given More NeuroBloc Than You Should

  • if you have been given more NeuroBloc than you need, some of your muscles that were not injected may feel weak or you may develop symptoms away from the injected muscles, like difficulty in swallowing or breathing. This may occur when higher doses of up to 15,000 units are given
  • if you have difficulty breathing or you are worried by any symptoms you develop away from the place of the injection, talk to your doctor immediately. If he/she is unavailable seek emergency assistance. You may need urgent medical treatment

A serious condition called “botulism” which causes paralysis of muscles and respiratory failure could occur if too much of the active ingredient (botulinum toxin) is injected into the body. If your doctor suspects that botulism may have occurred, you will be admitted to hospital and your breathing (respiratory function) will be monitored. Recovery usually takes place over a period of time.

Possible Side Effects

Like all medicines, this medicine can cause side effects, although not everybody gets them. They may happen days to weeks after you have had the injection. You may feel pain at the place where you had the injection, but this should wear off after a few minutes.

You may get a dry mouth and it might become difficult to swallow. In rare cases difficulty in swallowing may be severe and choking is possible. If your swallowing difficulty gets worse or you have choking or breathing problems, see a doctor immediately. You may need urgent medical treatment.

Aspiration pneumonia caused by food particles or vomit entering into the lungs, and respiratory disease, have been reported after treatment with botulinum toxins (Type A and Type B). These side effects have sometimes resulted in death and are possibly related to the spread of botulinum toxin to body parts away from the place where the injection is given.

  • dry mouth
  • difficulty swallowing
  • headache
