Metyrapone

About metyrapone

Metyrapone is a medicine which can be used to diagnose Cushings syndrom. It is also occasionally prescribed to treat Cushing's syndrome. Cushing's syndrome is a condition where the level of a substance, called cortisol, in your body is too high over a long period of time. Cortisol is a hormone which helps your body react in a normal way to stress. It also helps regulate your blood pressure, your immune system and your blood sugar levels. Your body normally keeps the level of cortisol within a certain range so that there is neither too much nor too little. When you produce too much cortisol, a number of symptoms can develop over time although these can be fairly nonspecific, such as putting on weight, muscle weakness and bruising easily. Metyrapone helps prevent the over-production of cortisol and this helps to control these symptoms.

Metyrapone is also used to treat some types of water retention caused by an increased amount of a hormone called aldosterone. This type of water retention can occur if you have a kidney problem, liver cirrhosis, eller hjärtsvikt. Water retention occurs when there is a build-up of fluid in your body. It can make your feet or face swollen and puffy.

This information will also be printed on the label of the pack to remind you about what the doctor said. Take the capsules exactly as your doctor tells you to.

• Swallow the capsules whole - do not chew them before you swallow.
