Many people take common medications assuming they are harmless, simply because they are familiar. Yet doctors are increasingly warning that some widely used drugs — especially when taken long term or combined without guidance — may carry risks that often go unnoticed.A cardiologist has recently drawn attention to this issue, noting that medications prescribed routinely for pain relief, digestion, or congestion can quietly affect cardiovascular health, kidney function, and nutrient balance. His warning echoes guidance already issued by NHS, particularly regarding prolonged or unsupervised use.
One of the most frequently prescribed medications in the UK is Omeprazole, which was dispensed more than 73 million times in 2022 and 2023. It is commonly used to treat heartburn and acid reflux and is often paired with painkillers like Ibuprofen to reduce stomach irritation. While effective in the short term, the NHS advises that omeprazole should not be taken for more than two weeks without medical supervision.Long-term use has been associated with reduced absorption of key nutrients such as magnesium, iron, and vitamin B12. These deficiencies can affect energy levels, bone strength, nerve function, and heart health. According to Dr Aurelio Rojas, regular use without proper oversight may quietly undermine recovery, physical performance, and cardiovascular stability — especially in people who exercise frequently.
Painkillers like ibuprofen, diclofenac, and naproxen carry their own concerns. Dr Rojas cautions that taking these medications before workouts can strain the kidneys and increase cardiovascular risk, particularly during dehydration. Nonsteroidal anti-inflammatory drugs (NSAIDs) reduce pain and inflammation, but they also affect blood flow to the kidneys and heart. During intense exercise, this combination can elevate the risk of kidney injury or, in rare cases, heart events.
Other medications deserve attention as well. Nasal decongestants may raise blood pressure and heart rate during physical activity. Some blood pressure medications can lower essential minerals such as potassium or magnesium. Certain antidepressants may affect the heart’s electrical rhythm, increasing the risk of arrhythmias during high-intensity exercise.
