It does not contain all of the available information. It does not take the place of talking to your doctor or pharmacist.

What Spiractin is used for
Spiractin is used:
- to treat essential hypertension (high blood pressure with an unknown cause)
- to treat oedematous disorders (swelling with fluid), including congestive cardiac failure
- to help bring potassium levels in the blood back to normal when the levels become too low
- to treat hyperaldosteronism (a hormone disorder causing fluid retention)
- as add on therapy in malignant hypertension (a very serious form of high blood pressure)
- treat excess facial or body hair in women.
Ask your doctor if you have any questions about why this medicine has been prescribed for you. Your doctor may have prescribed it for another reason.
This medicine is available only with a doctor's prescription.
There is no evidence that Spiractin is addictive.
How Spiractin works
In fluid build-up and high blood pressure
Spiractin is a fluid tablet or diuretic. It helps reduce the amount of excess fluid in the body by increasing the amount of urine produced. This also helps to lower blood pressure.
In hyperaldosteronism and low potassium levels in the blood
In hyperaldosteronism, the adrenal glands produce too much of a hormone called aldosterone. Spiractin works by stopping the effects of aldosterone.
By stopping the effects of aldosterone, Spiractin also helps to maintain normal levels of potassium in the blood by retaining potassium in the body.
In women with excess hair
All women produce small amounts of the male sex hormone, testosterone. Women with excess facial or body hair tend to be especially sensitive to the action of testosterone on hair growth. Spiractin reduces the growth of hair by stopping the effects of testosterone. Increased urine flow is unlikely to be a problem when Spiractin is used to treat hirsutism. This is because aldosterone levels are not normally high in patients with hirsutism.
