What is Guanfacine HCl ER 2 mg (extended-release) tablet used for?
Guanfacine hydrochloride extended-release (ER) tablets are prescribed to treat attention-deficit/hyperactivity disorder (ADHD) in certain patients. ER formulations are designed to release the medicine gradually over the day. (Specific labeling details like age/indication wording depend on the exact product and country.)
How should Guanfacine HCl ER 2 mg be taken?
Extended-release guanfacine is taken on a schedule set by the clinician. Because it’s an ER product, tablets generally shouldn’t be crushed, chewed, or split unless the prescribing information for that specific brand says otherwise. If you tell me the brand name (or share the label directions), I can align the instructions more closely to that exact product.
What are the common side effects patients ask about?
Patients commonly report dose-related side effects from guanfacine, such as sleepiness or fatigue, dizziness, low blood pressure, dry mouth, and constipation. Contact a clinician promptly for symptoms of significant low blood pressure (like fainting) or unusual reactions.
Why do people get monitoring for blood pressure and heart rate?
Guanfacine can lower blood pressure and slow the heart rate, so clinicians often monitor vitals—especially during dose changes—to reduce the risk of dizziness or fainting.
What happens if you miss a dose or stop abruptly?
If a dose is missed, the next dose is usually taken at the next scheduled time (not doubled). Stopping guanfacine abruptly may increase the chance of rebound symptoms; clinicians typically taper when discontinuing. Follow the plan provided by your prescriber.
Drug interactions: what to watch for
Guanfacine ER levels can change with certain medications (for example, some strong inhibitors or inducers of drug-metabolizing enzymes). Alcohol and other medicines that cause sedation can add to drowsiness. Share your medication list (including OTC products) if you want interaction-specific guidance.

Quick check: what do you mean by “2 mg tablet”?
“Guanfacine HCl ER 2 mg” could refer to different product labels (brand/manufacturer). If you provide:
1) the brand name on your bottle, and
2) whether it’s for ADHD or another condition,
I can give more precise dosing and safety information tied to that label.
