When we think of salt and high blood pressure, food is usually the first thing that comes to mind. But did you know that some medicines themselves contain hidden salt?
Effervescent tablets, soluble painkillers, antacids, and even certain syrups use sodium compounds (like sodium bicarbonate) to dissolve quickly or improve taste. For a healthy person, this may not be a big issue. But for people with hypertension, kidney disease, or heart failure, these extra doses of sodium can silently worsen their condition.
For example, some soluble painkillers may contain as much as 1 gram of sodium per tablet, almost half of the daily recommended limit. If taken regularly, this can add up quickly without the patient even realizing it.
What can be done?
-
Pharmacists should guide patients about hidden sodium in medicines.
-
Doctors can choose low-sodium alternatives where possible.
-
Patients should always check labels and ask questions, especially if on a low-salt diet.
Should drug manufacturers be required to clearly label sodium content on medicine packs, just like on food products?
