Which medication requires monitoring of blood pressure due to potential side effects?

Nifedipine is the medication that requires monitoring of blood pressure due to its potential side effects. As a calcium channel blocker, it is primarily used to treat hypertension and to control angina. Nifedipine works by relaxing the blood vessels, which can lead to a reduction in blood pressure. However, it may also cause hypotension (abnormally low blood pressure) as a side effect, especially if taken in certain formulations or dosages. Therefore, it is critical to monitor the patient’s blood pressure to ensure it remains within a safe range and to adjust the treatment plan as necessary.

The other medications listed do not typically require as close monitoring of blood pressure. Albuterol, for instance, is primarily a bronchodilator used in asthma and may occasionally cause an increase in heart rate, but it does not directly affect blood pressure in a significant manner. Digoxin is used to manage heart failure and atrial fibrillation and requires monitoring for heart rate and signs of toxicity rather than blood pressure itself. Levothyroxine, a thyroid hormone replacement, can influence metabolism and potentially cause symptoms like palpitations or increased heart rate, but again, blood pressure monitoring is not typically emphasized with its use.
