Other special warnings
You should take the lowest dose of Voltarol for the shortest possible time, particularly if
you are underweight or elderly.
There is a small increased risk of heart attack or stroke when you are taking any medicine

the doctor’s instructions on how much to take and how long to take it for.

time to time.
If you have a history of stomach problems when you are taking NSAIDs, particularly if you
are elderly, you must tell your doctor straight away if you notice any unusual symptoms.

infection, for example, headache and high temperature. If you feel unwell and need to see
a doctor, remember to tell him or her that you are taking Voltarol.
