What is guanfacine ER 2 mg used for?
Guanfacine ER 2 mg is a controlled-release form of guanfacine, typically used to treat attention-deficit/hyperactivity disorder (ADHD) in children and/or adults (depending on local prescribing guidance). It may also be used for other conditions where an extended-release alpha-2A agonist is appropriate, but the exact indication depends on the country and the specific product label.
How should guanfacine ER 2 mg be taken?
Extended-release tablets are usually taken once daily, consistently at the same time each day. Swallow the tablet whole and do not crush, split, or chew unless the product labeling specifically allows it. Dose changes are often done gradually to reduce side effects such as low blood pressure or dizziness.
What are common side effects of guanfacine ER?
Common side effects often include sleepiness or fatigue, dizziness, dry mouth, constipation, and low blood pressure. Some people also experience headache or slowed heart rate. Because guanfacine can affect blood pressure, clinicians typically monitor for symptoms like lightheadedness, fainting, or unusual weakness.
What precautions matter most with guanfacine ER?
Key precautions include:
- Avoid sudden stopping without medical advice. Stopping can worsen symptoms or cause changes in blood pressure/heart rate.
- Be careful with other medicines that lower blood pressure or affect heart rate.
- Use extra caution if you have a history of low blood pressure, fainting, or heart rhythm problems.
- Alcohol and sedating medications can increase drowsiness.
Is guanfacine ER 2 mg the same as immediate-release guanfacine?
No. Guanfacine ER (extended-release) and immediate-release guanfacine have different dosing schedules and drug-release profiles, so they are not interchangeable on a milligram-for-milligram basis. If you’re switching formulations, your prescriber should adjust the dose and timing.
What happens if you miss a dose?
If you miss a dose, take it when you remember on the same day unless it is close to the next scheduled dose. If it’s near the next dose, skip the missed dose and continue your regular schedule. Do not take a double dose.
