What is guanfacine HCl ER (extended-release) and what is it used for?
Guanfacine HCl ER is an extended-release form of guanfacine, a medicine used to treat attention-deficit/hyperactivity disorder (ADHD) in certain patients. Extended-release tablets are designed to release the drug slowly over time to help manage symptoms across the day.
What does “1 mg tablet” mean for dosing?
“1 mg tablet” means each extended-release tablet contains 1 milligram of guanfacine hydrochloride. The correct dose depends on the patient and prescriber instructions, and it may be adjusted based on response and side effects.
How is guanfacine ER usually taken?
Because it is an extended-release tablet, it is typically taken on a schedule (often once daily) as directed by a clinician. Patients generally should not crush, split, or chew extended-release tablets unless a prescriber or product instructions say it is allowed.
What side effects do people commonly ask about?
Commonly reported side effects for guanfacine ER can include sleepiness or tiredness, low blood pressure (dizziness/lightheadedness), dry mouth, and constipation. Patients often ask about sedation and feeling lightheaded when standing.
What safety issues matter most (blood pressure, driving, and other meds)?
Guanfacine can lower blood pressure and slow heart rate in some people, so dizziness or faintness can matter for safety, including driving or operating machinery. Drug interactions can also matter, particularly with medicines that affect blood pressure, heart rate, or sedation.
What if a dose is missed or timing is off?
If a dose is missed, patients usually should follow the instructions provided with their specific product or by their prescriber. Because this is an ER formulation, patients often need guidance on whether to take the missed dose or skip it, based on how close it is to the next scheduled dose.
