Lyzalon helps most people with neuropathic pain or epilepsy, but it may have unwanted
side effects in a few people. All medicines can have side effects. Sometimes they
are serious, most of the time they are not. You may need medical attention if you
get some of the side effects.
It can be difficult to tell whether side effects are the result of taking Lyzalon,
effects of your condition or side effects of other medicines you may be taking. For
this reason it is important to tell your doctor of any change in your condition.
If you are over 65 years of age you may have an increased chance of getting side effects.
Do not be alarmed by the lists of side effects. You may not experience any of them.
If you get any side effects, do not stop taking Lyzalon without first talking to your
doctor or pharmacist.
Ask your doctor or pharmacist to answer any questions you may have.

mild and short-lived.

unusual changes in mood or behaviour
signs of new or increased irritability or agitation

swelling of the hands, ankles or feet
enlargement of breasts

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 that is making you feel unwell.
Other side effects not listed above may also occur in some people.
Some of these side effects (for example, changes in blood pressure) can only be found
when your doctor does tests from time to time to check your progress.
