Calling out the “common belief” that taking blood pressure medicines daily can harm the kidneys, Dr Parin Sangoi, a consultant interventional cardiologist at Wockhardt Hospitals, Mumbai Central, stressed that this is “not correct.” “Blood pressure medicines do not damage the kidneys. In fact, untreated high blood pressure is a major cause of kidney disease. When blood pressure remains elevated for extended periods, it damages the small blood vessels in the kidneys, gradually reducing their ability to filter waste. This often happens quietly and may go unnoticed for years,” Dr Sangoi told indianexpress.com.
The cardiologist clarified that in many cases, kidney damage has already begun by the time high blood pressure is found. “Once treatment starts and blood pressure is controlled, routine tests may reveal existing kidney issues. This timing can lead people to wrongly blame the medicines when the damage was actually caused by long-term untreated hypertension,” said Dr Sangoi.
If blood pressure readings become normal, why shouldn’t medication be stopped?
Normal blood pressure readings indicate that the treatment is effective. “High blood pressure is usually a lifelong condition. Stopping medication suddenly can cause blood pressure to rise again, often without any warning symptoms. This sudden increase adds stress to the heart, brain, and kidneys, increasing the risk of heart attack, stroke, and further kidney damage,” said Dr Sangoi.

How risky is stopping blood pressure medicines without medical advice?
Stopping on your own is one of the most common and serious mistakes, Dr Sangoi emphasised. “Many patients stop their medicines based on tips from social media, friends, or because they feel fine. This can lead to uncontrolled blood pressure and the quick progression of organ damage. A doctor should always supervise any change in dosage or stopping.”
Can lifestyle changes or alternative therapies replace blood pressure medicines?

Healthy lifestyle habits can help control blood pressure and improve overall health, but they should not replace prescribed medications without consulting a doctor. In some cases, lifestyle improvements may allow for a lower dose, but completely stopping medication requires careful monitoring.
What is the key takeaway for patients?
Blood pressure medicines protect vital organs. “They prevent long-term complications rather than cause them. Decisions about stopping or changing treatment should always be based on medical advice, not myths or fear,” said Dr Sangoi.
