Many people assume common medications are harmless simply because they are familiar. Yet doctors warn that some widely used drugs, especially when taken long term or combined without guidance, can carry hidden risks.

A cardiologist recently highlighted that medications for pain, digestion, or congestion can quietly affect cardiovascular health, kidney function, and nutrient balance. His warning aligns with NHS guidance on unsupervised or prolonged use.

Omeprazole, prescribed more than 73 million times in 2022 and 2023 in the UK, is commonly used for heartburn and acid reflux. While effective short-term, the NHS advises it should not be used for more than two weeks without medical supervision.

Long-term use of omeprazole can reduce absorption of magnesium, iron, and vitamin B12. These deficiencies may affect energy, bone strength, nerve function, and heart health. Dr. Aurelio Rojas notes that regular unsupervised use may undermine recovery, performance, and cardiovascular stability.

Painkillers like ibuprofen, diclofenac, and naproxen also carry risks. Dr. Rojas warns that taking them before exercise can strain the kidneys and increase cardiovascular risk, particularly when dehydrated. NSAIDs reduce pain but can affect blood flow to the kidneys and heart.

Other medications also warrant caution. Nasal decongestants may raise blood pressure and heart rate during activity. Some blood pressure drugs lower essential minerals, while certain antidepressants can alter the heart’s rhythm, increasing arrhythmia risk during intense exercise.

These warnings do not mean the drugs should be avoided altogether. Dr. Rojas emphasizes awareness: people often take medications without realizing how they interact with exercise, hydration, or other drugs.

Reviewing medications with a healthcare professional, especially when exercising or combining drugs, helps preserve their benefits and avoid hidden risks, ensuring long-term well-being rather than unintended harm.
