Why have I been prescribed Capoten?
- Capoten (Captopril) 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.
- In addition, Capoten can be used for the treatment of kidney disease in patients with diabetes.
How does it work?
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.
When and how do I take it?
- You should try to take Capoten at about the same time each morning. It can be taken before, during or after meals.
- Even if you feel well continue to take Capoten until your doctor tells you otherwise.
- Sometimes patients may feel dizzy after taking the first one or two doses of Capoten. If this happens to you, lie down until these symptoms disappear.
What’s the dose?
The usual doses are:
For the treatment of high blood pressure:
- The usual starting dose is 12.5 - 25mg twice a day. Your doctor may gradually increase this dose to 100 - 150mg a day. You may also need to be given other medicines to lower your blood pressure.
- Older patients and those with kidney problems may be given a lower starting dose.
In heart failure:
- The usual starting dose is 6.25 – 12.5mg two or three times a day. Your doctor may gradually increase this dose to a maximum of 150mg a day.
After a heart attack:
- The usual starting dose is 6.25mg, which will then be increased by your doctor to a maximum of 150mg a day.
For the treatment of diabetic patients with kidney disease:
- The usual dose is 75 - 100mg a day.
- The starting dose is 0.3mg/kg bodyweight, which may be increased gradually by the doctor. For children with kidney problems, premature babies and newborn babies and infants, the starting dose should be 0.15mg/kg bodyweight.
