What doses of guanfacine ER are available?
Guanfacine extended-release (ER) tablets come in multiple strength options, typically including 1 mg, 2 mg, and 3 mg doses.
How is guanfacine ER usually started and titrated?
Common prescribing practice is to start at a low dose and increase gradually based on response and tolerability. A typical titration pattern is:
- Start: 1 mg once daily
- Increase: by 1 mg increments
- Usual target range: up to 4–7 mg once daily depending on the condition and the specific prescriber guidance
- Maximum: often up to 7 mg/day in many labeling practices
How should guanfacine ER be taken (timing and with food)?
Guanfacine ER is taken once daily. Consistency matters—take it the same time each day. Some formulations have food-related absorption considerations, so follow the product labeling or prescriber instructions for whether to take with or without food.
What if a dose is missed?
If you miss a dose, take it when you remember unless it is close to the next scheduled dose. Do not take two doses at once. If you miss several doses in a row, contact your prescriber for guidance before restarting.
What side effects and safety issues affect dose decisions?
Dose adjustments often depend on side effects such as:
- Low blood pressure or dizziness
- Sleepiness/fatigue
- Headache
- Dry mouth
Stopping suddenly can also be risky for some patients, so dose changes should be supervised by a clinician.
Which exact guanfacine ER product do you mean?
Dosing can vary slightly by indication (for example, ADHD) and by the specific product/labeling. If you tell me the country (or the brand name on the bottle) and what it’s for, I can give the most accurate dose schedule.
If you share your tablet strength (e.g., 1 mg/2 mg/3 mg) and the reason you’re taking it, I can map out the usual step-up plan more precisely.
