Metoprolol comes in the form of a tablet taken orally and it is required to be taken with food or right after a meal, otherwise there would be unfavorable effects to the stomach and may cause pain. Metoprolol dosage varies depending on a couple of factors including the nature of the disease being treated, and the age and specific conditions of the patient like weight and allergic reactions.
Usual Metoprolol Dosage
The usual dosage for diseases such as hypertension, angina pectoris prophylaxis, and supraventricular tachycardia is 100 to 450 milligrams per day. This is for adults or people of ages 18 and above. Extended release or metoprolol succinate can be taken at the same total daily dose once everyday. Moreover, the usual adult dosage for congestive heart failure in extended release formulation is 25 to 200 mg taken once everyday for 14 days. This is for patients suffering from mild failure. The dosage for patients with the more severe heart failure is 12.5 to 200 mg in extended release formula, taken once everyday for 14 days. For pediatric patients or patients with ages 17 and below, on the other hand, metoprolol dosage in immediate release formulation for hypertension is 1 to 6 mg/kg per day. In extended release formulation, only applying for patients 6 years old to 16 years old, dosage is 1 mg/kg taken once on a daily basis.
What You Should Know
These are just some examples of metoprolol dosage according to disease and patient’s age, and these are not exact doses. An initial dose is different from the maintenance, and shall increase or decrease after a certain period of time. Doses are usually adjusted based on the patient’s response – increased until blood pressure is reduced to the maximum level or until the right heart rate is attained, and decreased if patients experience extremely slow heart rate or bradychardia. If the condition of a person with heart failure worsens, an increased dosage of diuretics is one way of treatment. Whether it be required that the dose be reduced or stopped temporarily, it is important that the dose is not increased until there is stabilized condition. Consequently, blood pressure should be observed regularly to determine if the dose is maintaining full effect or if adjustments should be done.
The dosage of metoprolol is also adjusted depending on existing condition of patients. For example, it is recommended that a patient’s metoprolol intake is controlled if he is suffering from diseases involving the liver, because there are higher chances of blood level increase in a person with a poorly functioning liver. Meanwhile, there should be no problem with patients with kidney complications because the kidney will not be directly affected by the medicine. Elderly patients, moreover, should be extra cautious since they have bodies with decreased organ functions.
It is very important that one does not overdose on not only metoprolol but all other medicines because excessive doses, as well as incorrect metoprolol dosage, may lead to a number of serious problems. For instance, overdosing metoprolol can result to a drastic fall in blood pressure, metabolic acidosis, and problems in the cardiorespiratory. Should there be an overdose, however, one should immediately call the attention of the doctor.
