The name of your medicine is Indapamide 2.5mg Tablets (called indapamide throughout this leaflet). It belongs to a group of medicines called diuretics (water tablets).

Indapamide can be used for treating:

  • High blood pressure (hypertension). It may be used on its own or in combination with other medicine for high blood pressure.

Most diuretics increase the amount of urine produced by the kidneys. However, indapamide is different from other diuretics, as it only causes a slight increase in the amount of urine produced. In addition, indapamide widens blood vessels so that blood passes through more easily. This helps lower blood pressure.


Do not take indapamide if:

  • if you are allergic (hypersensitive) to indapamide, any other sulfonamide or to any of the other ingredients of this medicine (listed in section 6).
  • if you have severe kidney disease
  • if you have severe liver disease or suffer from a condition called hepatic encephalopathy (liver problems which affect your brain and central nervous system)
  • if you have low levels of potassium in your blood (hypokalaemia)

Do not take the medicine if any of the above applies to you. If you are not sure, talk to your doctor or pharmacist before taking indapamide.

Warnings and precautions

Talk to your doctor or pharmacist before taking indapamide:

  • if you suffer from gout or have diabetes
  • if you have kidney problems
  • if you have or have ever suffered from an overactive parathyroid gland (hyperparathyroidism) leading to too much calcium in the blood
  • if you have heart rhythm problems
  • if you have liver problems
  • if you experience a decrease in vision or eye pain
    These could be symptoms of fluid accumulation in the vascular layer of the eye (choroidal effusion) or an increase of pressure in your eye and can happen within hours to weeks of taking indapamide. This can lead to permanent vision loss, if not treated. If you earlier have had a penicillin or sulfonamide allergy, you can be at higher risk of developing this.

You should tell your doctor if you have had photosensitivity reactions.

Your doctor may give you blood tests to check for low sodium or potassium levels or high calcium levels.

Athletes should be aware that this medicine contains an active ingredient, which may give a positive reaction in doping tests.

If you think any of these situations may apply to you or you have any questions or doubts about taking your medicines, you should consult your doctor or pharmacist.

Other medicines and indapamide

Driving and using machines:

This medicine can cause side effects such as tiredness or dizziness due to lowering of the blood pressure (see section 4). These side effects are more likely to occur after the initiation of the treatment and after dose increases. If this occurs, you should refrain from driving and other activities requiring alertness. However, under good control, these side effects are unlikely to occur.

If you are not sure if any of the above apply to you, talk to your doctor or pharmacist before taking indapamide.
