Summary
The aspirin in this effervescent product, when taken at analgesic doses, can reduce telmisartan's antihypertensive effect and impair renal function. The sodium load may also contribute to reduced blood pressure control.
What this interaction means in plain words
Aspirin / citric acid / sodium bicarbonate and Telmisartan can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.
Why it happens
Aspirin inhibits renal prostaglandins, reducing renal perfusion and sodium excretion, while sodium bicarbonate adds a sodium load.
What to do
Limit use to short courses and monitor blood pressure, creatinine and potassium. Prefer paracetamol in patients with heart failure, kidney disease or poorly controlled hypertension.
