What is Indapamide?

Indapamide is a type of medicine called a diuretic which is used to treat high blood pressure. It can also be used to decrease the extra fluid which is caused by heart failure. 

How does Indapamide work?

Indapamide works by increasing the body's production of urine, allowing it to flush out excess fluids and salts. This helps to reduce the blood pressure and ease symptoms like swollen ankles and shortness of breath.

Treatment Options

Alternatives to Indapamide

Bendroflumethiazide is a diuretic which works in the same way as Indapamide to treat high blood pressure. There are four other types of medicines given to treat high blood pressure: 

  • ACE inhibitors- these work by relaxing the blood vessels to make it easier for the blood to flow. These will usually be prescribed in the first instance for patients under the age of 55

  • ARBs (Angiotensin-2 receptor blockers)- These also relax the blood vessels and are predominantly prescribed for patients over 55 or those of an African or Caribbean ethnicity

  • Calcium channel blockers- these work by widening the blood vessels to lower the blood pressure 

  • Beta-blockers- These are usually prescribed if other treatments haven't been successful and work by slowing the heart rate

Can Lifestyle changes help?

Everyone with high blood pressure is encouraged to make lifestyle changes to improve their overall health and lower their blood pressure. This includes: 

  • Eating a low salt diet with a maximum of 6g per day 

  • Eating a healthy diet with at least 5 portions of fruit and vegetables per day 

  • Exercise regularly 

  • Reduce alcohol consumption 

  • Quit smoking 

  • Maintain a healthy weight 

  • Cut down on caffeine

These changes can help you to prevent high blood pressure from occurring and reduce your need for medication.
