Guanfacine

Drug Details

Guanfacine is a medication prescribed to manage high blood pressure, particularly in individuals aged 12 and older. It functions by targeting receptors in the brain that reduce the action of norepinephrine, a chemical that normally increases blood pressure by tightening blood vessels. By decreasing this chemical's effect, guanfacine allows blood vessels to relax, enhancing blood flow and lowering heart rate, which in turn reduces blood pressure. Typically taken once daily, preferably at night, guanfacine may cause side effects such as sleepiness, dizziness, and dry mouth. It is important to consult with a healthcare professional before combining it with other medications, as interactions can exacerbate these side effects.
