Can I take Idapamide and Ramipril together?

Why this happens

Both medicines work to lower blood pressure but in different ways. Indapamide is a 'water tablet' (diuretic) that removes salt and water from the body, while ramipril relaxes blood vessels. When used together, their effects add up. Additionally, if the water tablet has made you slightly dehydrated, the first dose of ramipril can cause a sudden, sharp drop in blood pressure and affect how well your kidneys filter blood.

What you should do

Your doctor may advise you to stop taking indapamide for a few days before starting ramipril, or start you on a very low dose of ramipril. It is best to take your first dose of ramipril at bedtime to avoid dizziness. If you feel very dizzy or faint, sit or lie down immediately and contact your doctor. Your doctor will likely perform blood tests to check your kidney function and salt levels (electrolytes) regularly.

Important precautions

Embarazo

You must not take this medicine if you are pregnant or planning to become pregnant, as it can cause serious harm or death to an unborn baby. Use effective contraception while taking it.

Angioedema (Swelling)

Seek emergency medical help immediately if you experience swelling of the face, lips, tongue, or throat, as this medicine can cause a rare but life-threatening allergic reaction called angioedema.

Dehydration and Electrolyte Imbalance

These medicines can significantly alter your salt and potassium levels. You must have regular blood tests and seek medical advice if you experience severe diarrhoea, vomiting, or signs of dehydration, as this can lead to kidney problems.

Food and drink warnings

Alcohol

Drinking alcohol can increase the blood pressure-lowering effect of these medicines, which may make you feel dizzy, lightheaded, or faint, especially when standing up. It is best to keep alcohol intake to a minimum, especially when starting these medicines or changing your dose.

Salt substitutes (Potassium-based)

Ramipril can increase the levels of potassium in your blood. Many salt substitutes (such as Lo-Salt) contain potassium chloride instead of sodium. Using these while taking Ramipril can lead to dangerously high potassium levels (hyperkalaemia). Check with your pharmacist before using salt substitutes.
