Fertility, pregnancy and breast feeding
Based on the information available, effects
on fertility are not known but cannot be
excluded. You should not use IMMUKIN
during pregnancy, unless your doctor thinks
it is essential. You are recommended not to
breast-feed while using IMMUKIN.
Ask your doctor or pharmacist for advice
before using any medicine.
Driving and using machines
IMMUKIN can cause fatigue, fits (seizures),
confusion, disorientation or distorted or
imaginary sensations (hallucinations). These
side effects can reduce the ability to
respond and can thus have a negative effect
upon the ability to drive and use machines.
Do not drive or use machines if you realize

4. POSSIBLE SIDE EFFECTS
Like all medicines, IMMUKIN can cause side
effects, although not everybody gets them.
The risk of side effects occurring depends
on the dose and the dosing schedule you
have been given.
The most common side effects are flu-like
symptoms such as fever, headache, cold
chills, and fatigue.
These may become less severe over time as
the treatment is continued. Some of these
symptoms can be reduced by administering
IMMUKIN just before going to sleep. A
medicine such as paracetamol can be used
to reduce some of these side effects.
Reporting of side effects
If you get any side effects, talk to your
doctor, pharmacist or nurse. This includes
any possible side effects not listed in this
leaflet. You can also report side effects
directly (see details below). By reporting
side effects you can help provide more
information on the safety of this medicine.
