What is an important patient counseling point for guanfacine?

Guanfacine is an alpha-2 adrenergic agonist commonly used to treat hypertension and attention deficit hyperactivity disorder (ADHD). A critical counseling point is the need to avoid alcohol and central nervous system (CNS) depressants while taking this medication. Ethanol can enhance the sedative effects and hypotensive properties of guanfacine, leading to heightened drowsiness and a risk of significant drops in blood pressure. Patients need to be aware of these interactions to prevent adverse effects on their mental and physical well-being.

The other options, while relevant, do not hold the same level of importance for patient safety regarding guanfacine. For instance, while taking it with food can be advised for other medications, it is not a specific requirement for guanfacine. Additionally, although guanfacine may be used in combination with other antihypertensives under doctor supervision, this is less critical than the need to avoid alcohol and CNS depressants. Lastly, the recommendation to discontinue guanfacine immediately could also lead to withdrawal symptoms, emphasizing the importance of a proper tapering schedule instead of abrupt cessation.
