Always take these tablets exactly as your
doctor has told you. The label on your
medicine will tell you how many tablets to
take and how often.
The dosage should be adjusted to the
intensity of your pain and your individual
pain sensitivity. In general the lowest painrelieving dose should be taken.
Adults and children over 12 years of age
The usual starting dose is one 75 mg tablet
twice a day. However, your doctor will
prescribe the dose required to treat your
pain. If you find that you are still in pain
whilst taking these tablets discuss this with
your doctor. You should not normally take
more than 400 mg a day.
In elderly patients (above 75 years) the

may be rapidly absorbed into your
body. This can be dangerous, causing
problems such as an overdose, which
may be fatal.

12 hours. For instance, if you take a
tablet at 8 o’clock in the morning, you
should take your next tablet at 8 o’clock
in the evening.

your tablets unless your doctor tells
