Taking Longtec tablets with food,

Drinking alcohol whilst taking Longtec
tablets may make you feel more sleepy
or increase the risk of serious side
effects such as shallow breathing with
a risk of stopping breathing, and loss of
consciousness. It is recommended not
to drink alcohol while you are taking
Longtec tablets. You should avoid
drinking grapefruit juice during your
treatment with this medicine.
Pregnancy and breastfeeding
Do not take these tablets if you are
pregnant or breastfeeding.
Ask your doctor or pharmacist for advice
before taking any medicine.
Driving and using machines
These tablets may cause a number of
side effects such as drowsiness which
could affect your ability to drive or use
machinery (see section 4 for a full list
of side effects). These are usually most
noticeable when you first start taking
the tablets, or when changing to a higher
dose. If you are affected you should not
drive or use machinery.

This medicine can affect your ability to
drive as it may make you sleepy or dizzy.
• Do not drive while taking this
medicine until you know how it
affects you.
• It is an offence to drive while you
have this medicine in your body
over a specified limit unless you
have a defence (called the ‘statutory
• This defence applies when:

to treat a medical or dental
problem; and
• You have taken it according to the

form of sugar. If you have been told by
your doctor that you have an intolerance
to some sugars, contact your doctor

3. How to take Longtec tablets
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.
Adults (over 18 years of age)
The usual starting dose is one 10 mg
tablet every 12 hours. 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.
Do not exceed the dose recommended by
your doctor. You should check with your
doctor or pharmacist if you are not sure.
Swallow your tablets whole with water.
Do not crush, dissolve or chew them.
Longtec tablets are designed to work
properly over 12 hours when swallowed
whole. If a tablet is broken, crushed,
dissolved or chewed, the entire 12-hour
dose may be absorbed rapidly into your
body. This can be dangerous, causing
serious problems such as an overdose,
which may be fatal.
You should take your tablets every
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.
You must only take the tablets by mouth.
The tablets should never be crushed or
injected as this may lead to serious side
effects, which may be fatal.
