What Morfaza tablets are and what they are used for

These tablets have been prescribed for you by your doctor to relieve severe pain over a period of 12 hours. They
contain the active ingredient morphine which belongs to a group of medicines called strong analgesics or

What you need to know before you take Morfaza tablets

Do not take Morfaza tablets if:
you are allergic (hypersensitive) to morphine or any of the other ingredients of the tablets (see section
6 ‘Further Information’);
you have breathing problems, such as obstructive airways disease or respiratory depression. Your
doctor will have told you if you have these conditions. Symptoms may include breathlessness,
coughing or breathing more slowly or weakly than expected;
you have a head injury that causes a severe headache or makes you feel sick. This is because the
tablets may make these symptoms worse or hide the extent of the head injury;
you have a condition where the small bowel (part of your gut) does not work properly (paralytic
ileus), your stomach empties more slowly than it should (delayed gastric emptying) or you have
severe pain in your abdomen;
you have recent onset liver disease;
you are taking a type of medicine known as a monoamine oxidase inhibitor (examples include
tranylcypromide, phenelzine, isocarboxazid, moclobemide and linezolid), or you have taken this type
of medicine in the last two weeks;
the patient is under one year of age.
If you are going to have an operation, please tell the doctor at the hospital that you are taking these tablets.
Warnings and precautions
Talk to your doctor or pharmacist before taking this medicine if you:
have breathing problems, such as impaired lung function or severe bronchial asthma. Your doctor
will have told you if you have these conditions. Symptoms may include breathlessness and coughing;


have an under-active thyroid gland (hypothyroidism), severe kidney or liver problems as you may
need a lower dose;
have a severe headache or feel sick as this may indicate that the pressure in your skull is increased;
suffer from, or have ever suffered from epilepsy, seizures, fits or convulsions;
have low blood pressure;
have a severe heart problem after long-term lung disease (severe cor pulmonale);
have inflammation of the pancreas (which causes severe pain in the abdomen and back) or problems with
your gall bladder;
have an inflammatory bowel disorder;
have prostate problems;
have poor adrenal gland function (your adrenal gland is not working properly which may cause
symptoms including weakness, weight loss, dizziness, feeling or being sick);
are or have ever been addicted to alcohol or drugs;
have previously suffered from withdrawal symptoms such as agitation, anxiety, shaking or sweating,
upon stopping taking alcohol or drugs.

Very rarely you may experience increased sensitivity to pain despite the fact that you are taking increasing
doses of these tablets (hyperalgesia). Your doctor will decide whether you need a change in dose or a change
in strong analgesic (“painkiller”).

These tablets must not be used together with a monoamine oxidase inhibitor, or if you have taken this type
of medicine in the last two weeks (see section 2 ‘Do not take…’).

Driving and using machines

These tablets may cause a number of side effects such as drowsiness which could affect your ability to drive

Important information about some of the ingredients of Morfaza tablets
The 5 mg, 10 mg, 15 mg, 30 mg and 60 mg tablets contain lactose which is a form of sugar. If you have
been told by your doctor that you have an intolerance to some sugars, contact your doctor before taking
these tablets.
The 30 mg and 60 mg tablets contain sunset yellow (E110) which may cause allergic reactions.


How to take Morfaza tablets

Always take the tablets exactly as your doctor has told you. The label on your medicine will tell you how
many tablets to take and how often.
Swallow your tablets whole with a glass of water. Do not break, crush or chew them.
Morfaza tablets are designed to work properly over 12 hours when swallowed whole. If a tablet is
broken, crushed 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 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.
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.
The usual starting dose is one 30 mg tablet every 12 hours. However, the dose will depend on your age,
weight and the severity of your pain. If you are elderly or weigh less than 70 kg your doctor may suggest a
lower starting dose. Your doctor will decide how many tablets you should take.
Children over one year of age
Children over one year of age can take the tablets. The required dose will depend on their weight and
severity of pain. This should be discussed with your doctor or pharmacist.
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.
If you take more Morfaza tablets than you should or if someone accidentally swallows your tablets
Call your doctor or hospital straight away. People who have taken an overdose may feel very sleepy, sick or
dizzy. They may also have breathing difficulties leading to unconsciousness or even death and may need
emergency treatment in hospital. When seeking medical attention make sure that you take this leaflet and any
remaining tablets with you to show to the doctor.
If you forget to take Morfaza tablets
If you remember within 4 hours of the time your tablet was due, take your tablet straight away. Take your next
tablet at your normal time. If you are more than 4 hours late, please call your doctor for advice. Do not take a
double dose to make up for a forgotten tablet.
If you stop taking Morfaza tablets
You should not suddenly stop taking these tablets unless your doctor tells you to. If you want to stop taking
your tablets, discuss this with your doctor first. They will tell you how to do this, usually by reducing the
dose gradually so you do not experience unpleasant effects. Withdrawal symptoms such as agitation, anxiety,
shaking or sweating may occur if you suddenly stop taking these tablets.
If you have any further questions on the use of this medicine, ask your doctor or pharmacist.
