Before
taking your medicine

isosorbide dinitrate or lactose before?
- Do
you have low blood pressure, or are you already
taking medicine to lower blood pressure?
- Are
you pregnant or breast-feeding?
- Have
you ever suffered a heart attack?
- Do
you have any other problems with your heart or
circulation?
- Do
you suffer from severe anaemia?
- Do
you suffer from closed angle glaucoma (high pressure
in the eye)?
- Have
you suffered a head injury causing pressure in the

- Do
you suffer from the rare condition galactosaemia (an
inability to digest carbohydrates and sugars found
in food and milk products)?
- Do
you suffer from hypothyroidism (underactivity of the
thyroid gland)?
- Do
you suffer from malnutrition?
- Do
you have problems with your liver or kidneys?

If the
answer is YES to any of these questions do not take this
medicine until you have talked to your doctor about it.
Do not take
Viagra (sildenafil) or other treatments for erectile
dysfunction whilst taking Ismo Retard. If Viagra (sildenafil)
or other treatments for male erectile dysfunction are
used by patients taking nitrate preparations such as
Ismo Retard a severe and possibly dangerous fall in
blood pressure can occur. This would result in collapse,
unconsciousness and could be fatal.
Do
you have sudden anginal attacks?
Ismo
Retard tablets are used to
stop angina attacks from happening. They
cannot be used to
treat a sudden attack of angina. Your doctor will
probably have prescribed another treatment for you
to use for sudden attacks.
Do
you drive or operate machinery?
You may
feel dizzy or light-headed if you stand up or move
suddenly, or experience blurred vision. If you do,
you should not drive or operate machinery.
Taking your medicine
It is
important to take your Ismo Retard tablets at the
right time. You must take them in the morning as
your doctor has explained to you. The pharmacy label
will tell you how many to take, and how often. The
usual dose is one tablet daily. If you are not sure,
ask your doctor or pharmacist.
Please
swallow the tablets whole, with a drink of water. If
you forget to take a tablet, take one as soon as you
remember on that day. Continue your treatment as
usual the following morning.
Angina
needs treatment for life. Keep taking Ismo Retard
unless your doctor tells you to stop, or if the
tablets make you feel unwell. You may feel unwell if
you suddenly stop taking your tablets. Tell your
doctor if you stop taking this medicine.
If you
or anyone else accidentally take too many tablets
(overdose), tell your doctor at once, or contact the
nearest hospital casualty department. If you feel
faint or dizzy, lie flat with your legs raised
higher than your head.
After
taking your medicine
These
tablets may cause side effects in a few people. At the
start of treatment, you may have a headache or feel
dizzy but these effects should gradually go away.
Some people
may feel sick (nausea) or be sick (vomit) or feel weak.
A very few people may notice flushing, a fast heart
beat, itching or a rash. Some people may experience a
slowing of the heart beat and increase in chest pain.
You may feel
dizzy or light-headed if you stand up or move suddenly,
particularly if you have been drinking alcohol.
You should
tell your doctor if you have any of these effects or any
other effects which worry you.
In addition,
if you develop or experience worsening of chest pains,
contact your doctor.
