Indapamide

What is Indapamide?

Indapamide belongs to a class of drugs called diuretics – or water pills – and is used to treat high blood pressure and heart failure. Available via a doctor’s prescription, Indapamide comes in tablet form and can be used in combination with other blood pressure-reducing drugs to treat its symptoms. Taking this medication can effectively reduce the chance of experiencing a stroke, heart attack or kidney problems.

How does Indapamide work?

Indapamide works by increasing the frequency of urination, which helps the body to expel excess minerals such as potassium and sodium, and water through the kidneys. The decreased levels of salt and fluid allow the blood vessels to dilate which, in turn, helps to effectively reduce swelling and blood pressure commonly associated with various heart conditions.

How long does Indapamide take to work?

Indapamide usually begins to take effect within 2 hours of ingesting it. However, it could take anywhere up to a week before the initial effects of the medication are felt and up to a further 12 weeks to experience the full benefits of the drug.

How effective is Indapamide?

According to research, Indapamide is found to be more effective than many other drugs at controlling blood pressure and reducing the risk of heart failure. A single dose of Indapamide will lower the blood pressure for a minimum of 24 hours, which means that most users will only need to take it once a day. The medicines longer duration of action and increased efficacy in reducing blood pressure renders it a more viable treatment option than other diuretics.

Indapamide dosage

Indapamide tablets are available in 1.25 mg or 2.mg doses. If Indapamide is being used to reduce your blood pressure, generally you will start to take these tablets at a daily dose of 1.25mg, which your doctor may increase to a maximum of 5mg a day.

As Indapamide is a diuretic, it can also be used to encourage fluid loss. If you are taking Indapamide for this purpose, generally you will begin with 2.5mg per day, increasing to 5mg per day if needed.

What should I do if I miss a dose?

If you miss a dose of Indapamide you should take it as soon as possible, unless you are within 12 hours of your next dose. It is better to miss a dose completely, than to take too much Indapamide, which can have dangerous side effects.

How to take Indapamide

Indapamide is usually administered once a day – preferably in the morning. You must swallow the tablets whole with a glass of water, with or without food. Do not crush, break or chew the tablets as this can prevent them from working.

If you have difficulty swallowing the tablet, speak with your doctor for advice. It is important not to take the medication at night or too late in the day (after 4pm) as the increased inclination to urinate may disturb your sleep.
