About High Blood Pressure
High blood pressure is also called hypertension, according to the Mayo Clinic. Blood pressure shows how much blood is being pumped and how much resistance is offered by arteries. If the arteries are constricted or if the heart is pumping hard, blood pressure will be higher.
Hypertension usually develops over years. Because of this, it is important to take consistent blood pressure readings. Readings may vary, depending on the machine, but a consistent increase should be reported to a physician.
People should not stop taking metoprolol succinate abruptly, according to the Nursing Drug Handbook. They should be weaned off of it over one or two weeks.
Abrupt discontinuation of use can result in a heart attack, according to AstraZeneca.
Also, patients who are new to taking metoprolol succinate should avoid operating machines until they know how it will affect them, according to the manufacturer. Patients should also notify their doctors if they experience difficulty breathing.
Women who are nursing should not take metoprolol succinate, according to the Nursing Drug Handbook.
