Is it normal that after the first dose of Candesartan I am shaken and feel anxious?

This is not a typical and desirable reaction after taking Candesartan. Perhaps there has been too much reduction in blood pressure, such symptoms may give, for example, bradycardia, i.e. slowing down the rhythm of the heart. If the situation will also occur with the next dose of the drug, then it will be necessary to consult a doctor. It is worth measuring the pressure values and pulse - heart rate values below 60-50 contractions / minute may be worrying. The observed side effect of the therapy should be reported to the doctor.
