Which of the following symptoms should be reported to a healthcare provider when taking guanfacine?

When taking guanfacine, it is important to monitor for certain symptoms due to the medication's effects on blood pressure and vascular system. Guanfacine is an alpha-2 adrenergic agonist commonly used to treat attention deficit hyperactivity disorder (ADHD) and hypertension. One of its notable side effects is the potential to cause hypotension (low blood pressure) and peripheral edema (swelling of the extremities).

Signs of hypotension can include symptoms like dizziness, lightheadedness, or fainting, especially upon standing. Peripheral edema may manifest as swelling in the hands, feet, or legs. Reporting these symptoms is crucial because they can indicate that the body is having an adverse reaction to the medication that might require a dosage adjustment or an alternative treatment.

While headaches, dizziness, nausea, diarrhea, cough, and sore throat may occur, they are generally less urgent to report. Headaches and dizziness can occur with many medications and may not signify a serious issue. Nausea and diarrhea are common side effects, while cough and sore throat may be associated with other causes unrelated to guanfacine treatment. Monitoring and reporting hypotension and peripheral edema is vital for patient safety and effective management of treatment.
