Excuse me, have you ever been to a hospital for examination and been diagnosed with hypertension? Facial flushing, headache, palpitation, ankle and foot edema and other common adverse reactions may occur at the initial stage of taking amlodipine, which are mainly caused by dilating systemic blood vessels, and most of them can be tolerated. After taking 1 ~ 2 weeks, the adverse reactions can be obviously alleviated or disappeared without affecting the treatment.
