One or two extra tablets of hypertension medication will not usually cause a significant drop in blood pressure, as long as you take more rest and pay attention to measuring your blood pressure. If a lot more hypertension medication is taken, such as a dozen tablets, it may cause a significant drop in blood pressure, leading to hypotension and even shock and syncope, and immediate hospitalization is required. If the time from taking the medicine is short, gastric lavage can be performed to remove antihypertensive drugs, and if it is longer, infusion and expansion to raise blood pressure should be performed. Patients with signs and symptoms of shock have to use antihypertensive drugs, such as dopamine or norepinephrine. If the patient takes the drug betalactam, which causes a very slow heartbeat, atropine or isoprenaline can be used to raise the heart rate.
