A lot of people take their daily medication without a second thought. It’s part of a routine that feels safe and familiar.
But new findings suggest that even widely used treatments may carry risks that are not always fully understood.
According to LADbible, citing research reported by TCTMD, EurekAlert and Knowridge, scientists in the Netherlands and Denmark have identified a possible link between a popular blood pressure drug and an increased risk of cardiac arrest.
Unexpected findings
The medication, nifedipine, is commonly prescribed to treat high blood pressure and angina. It works by relaxing blood vessels, helping blood flow more easily and reducing strain on the heart.

However, recent analysis of large patient datasets has raised concerns. People taking higher doses, particularly 60 mg per day or more, appeared to face a greater risk of experiencing cardiac arrest outside of hospital settings.
The Dutch study compared more than 2,500 cardiac arrest patients with over 10,000 individuals without heart issues.
Danish data supported the findings, indicating the risk could be significantly higher at certain dosage levels.
Differences in treatment
Researchers also examined a similar drug, amlodipine, which belongs to the same class of medication. Unlike nifedipine, it did not show the same association with increased risk.

This contrast suggests that dosage and drug-specific effects may play a key role, even within the same category of treatment.
Key takeaways from the research include:
- Higher doses are linked to increased risk
- Lower doses showed no clear association
- Comparable drugs may not carry the same risk
What it means
The findings came as a surprise, given that nifedipine has been used safely by millions of patients over many years.
Earlier research had already hinted that certain forms of the drug, particularly short-acting high doses, might be linked to increased mortality in heart patients.
