1. What Capoten is and what it is used for
The name of this medicine is Capoten. Each tablet contains captopril (25mg) as the active ingredient.
Capoten belongs to the group of medicines called Angiotensin Converting Enzyme (ACE) Inhibitors.
ACE inhibitors work by helping to widen your blood vessels, which then make it easier for your heart to
pump blood through them.
Capoten is used to treat high blood pressure and certain heart conditions. If high blood pressure is left
uncontrolled it can increase the risk of heart disease or stroke. Capoten works by lowering your blood
pressure which reduces this risk.
Capoten can also help people whose heart no longer pumps blood as well as it once did.
This condition is known as heart failure.
Capoten may also be used to treat patients who recently suffered a heart attack. A heart attack happens
once one of the major blood vessels supplying blood to the heart muscle becomes blocked. This means
that the heart does not receive the oxygen it needs and the heart muscle becomes damaged.
In addition, Capoten can be used for the treatment of kidney disease in patients with diabetes.

2. What you need to know before you take Capoten
Do not take Capoten :
• if you allergic to captopril or any of the other ingredients of this medicine (listed in section 6).
• if you are more than 3 months pregnant. (It is also better to avoid Capoten in early pregnancy – see
pregnancy section.).
• if you have ever had an allergic reaction to any ingredients of Capoten or to any other medicines,
including other ACE inhibitors.
• if you have ever had a reaction which included swelling of the hands, lips, face or tongue where the
cause was unknown.
• if you suffer from any auto-immune disease (e.g. rheumatoid arthritis, systemic lupus erythematosus
or scleroderma).
• if you have diabetes or impaired kidney function and you are treated with a blood pressure lowering
medicine containing aliskiren.
If any of the above affects you, or you are unsure if they do, tell your doctor who will be able to advise
Warnings and precautions
Talk to your doctor or pharmacist before taking Capoten.
If you are taking any of the following medicines used to treat high blood pressure:
an angiotensin II receptor blocker (ARBs) (also known as sartans – for example valsartan,
telmisartan, irbesartan), in particular if you have diabetes-related kidney problems.

potassium) in your blood at regular intervals.
See also information under the heading ‘Do not take Capoten’.

• medicines that cause dilation of the blood vessels (e.g. minoxidil, clonidine).
• medicines to treat mental health problems including depression (such as lithium or amitriptyline).
• any other medicines to treat high blood pressure (e.g. beta-blockers such as propanolol, atenolol or
