Why this happens
Indapamide is a diuretic (water tablet) used to lower blood pressure, while vitamin C is a water-soluble vitamin. They are processed by the body through different pathways and do not interfere with each other's absorption, metabolism, or effectiveness.
What you should do
You can continue to take both as prescribed or recommended. As with any supplement, it is best to stick to the recommended daily allowance of vitamin C unless your doctor has advised otherwise.

Important precautions
Sulphonamide allergy
Do not take indapamide if you have a known allergy to sulphonamide medicines (such as certain antibiotics), as you may have a similar allergic reaction to this medicine.
Low potassium (hypokalaemia)
Indapamide can significantly lower your blood potassium levels. You must have regular blood tests to monitor this, especially if you experience muscle weakness, cramps, or an irregular heartbeat.
Kidney stones (oxalate)
High doses of Vitamin C can increase the risk of developing kidney stones. Avoid supplements if you have a history of calcium oxalate stones or severe kidney disease.
Food and drink warnings
Alcool
Drinking alcohol while taking indapamide can increase the blood-pressure-lowering effect of the medicine. This may make you feel dizzy, lightheaded, or faint, especially when standing up quickly. It is best to keep your alcohol intake within recommended limits and see how the medicine affects you before drinking.
