What should I do if my mother's severe symptoms, including a dry cough, nausea, dizziness, extreme weakness, and loss of appetite, are not improving even after switching from Sartel C 40 back to her original blood pressure medicine, Telma 40?
Switching back to Telma 40 (telmisartan) from Sartel C 40 (which contains a diuretic) was a reasonable step, but her symptoms of weakness, dizziness, and nausea might be due to dehydration or an electrolyte imbalance caused by the previous diuretic. Since she is not improving, please contact her doctor promptly. They will likely want to check her blood pressure and run a simple blood test to check her electrolyte levels. For now, encourage her to rest, sip water, and change positions slowly to prevent dizziness.
