What Innozide is and what it is used for

The effect of these medicines is to lower your blood pressure.

Routine tests
When you first start to take Innozide, your doctor will monitor your
blood pressure frequently to ensure you have been given the correct
dose. In addition, for some patients the doctor may want to do some
tests to measure your potassium, sodium, magnesium, creatinine
and liver enzyme levels.

medication can produce a positive result.
Innozide is not recommended for use in children.
Taking other medicines
Please tell your doctor or pharmacist if you are taking or have
recently taken any other medicines, including medicines obtained
without a prescription as some drugs may affect each other's action.
This includes herbal medicines. Also some other medicines can
affect the way Innozide works:
 potassium sparing water tablets (diuretics) such as
spironolactone, eplerenone, triamterene or amiloride, potassium
supplements, or potassium-containing salt substitutes. 'Innozide'
may increase the levels of potassium in your blood leading to
high potassium levels. This causes few signs and is usually seen
by a test.
 water tablets (diuretics) such as thiazides, furosemide,
 other medicines that lower blood pressure, such as
nitroglycerine, nitrates, and vasodilators
 lithium, used for the treatment of some psychiatric illnesses.
Innozide should not be taken with this drug
 barbiturates (sedatives used for sleeplessness or epilepsy)
 tricyclic antidepressants such as amitriptyline, used for
depression, antipsychotics such as phenothiazines, used for
severe anxiety
 pain killers such as morphine or anaesthetics, because your
blood pressure may become too low
 cholestyramine or colestipol (used to help control cholesterol

bones and joints:

face, feeling sick (nausea), vomiting and low blood
pressure, when taken with Innozide, and
 non-steroidal anti-inflammatory drugs (NSAIDs), for
example diflunisal or diclofenac. They may prevent your
blood pressure from being well controlled and may
increase the level of potassium in your blood
 medicines such as ephedrine, used in some cough and cold
remedies, or noradrenaline and adrenaline used for low blood
pressure, shock, cardiac failure, asthma or allergies. If used with
Innozide these drugs may keep your blood pressure high
 ACTH (to test whether your adrenal glands are working properly)
 Corticosteroids (used to treat certain conditions such as
rheumatism, arthritis, allergic conditions, asthma or certain blood
 Allopurinol (used to treat gout)
