Such a combination can be used for a short time and only after consulting a doctor. Combining Biofenac with Gisartan may lead, m.in to a weakening of the antihypertensive effect of Gisartan, to an increase in the concentration of potassium in the blood (manifested as apathy, muscle weakness, sensory disturbances, confusion, muscle cramps, as well as, less frequently, muscle paralysis and convulsions, circulatory symptoms - bradycardia, i.e. slowing down the heart, changes in the ECG) and deterioration of kidney function and even their failure. Therefore, Biofenac should be used as short as possible or replaced with an over-the-counter drug based on paracetamol, e.g. Apap, Efferalgan.
