Why did I increase my blood pressure after increasing the dose of Polsart from 40 mg to 80 mg instead of lowering?

Perhaps in your case, the cause of hypertension is different than the one on which Polsart works. According to the manufacturer: "In humans, a dose of 80 mg of telmisartan almost completely inhibits the increase in blood pressure caused by angiotensin II. This inhibitory effect persists for 24 hours and can still be detected after 48 hours." If, after increasing the dose, you do not observe satisfactory results, you should consult a doctor. It will be necessary to replace the drug with a preparation with a different mechanism of action.
