I was recently prescribed Guanfacine ER 4mg Tablets for my ADHD, and I've been using them for about a month now. This non-stimulant medication has been a game-changer in terms of improving my focus and attention, but I've also experienced some side effects that I wanted to discuss. The extended-release mechanism is great for once-daily dosing, but I've had a few issues with dizziness and fatigue. I'm hoping to find some tips and advice from others who have tried this medication. How have you managed any side effects, and what improvements have you seen in your ADHD symptoms? Let's share our experiences and support each other!

I've also experienced dry mouth, but chewing sugar-free gum helps a lot. Staying hydrated is key too!

I took Guanfacine ER for a few months and it was great for my focus, but I had some really bad constipation. My doctor suggested increasing my fiber intake and that helped a lot.

I tried Guanfacine ER and it didn't work for me. I switched to a stimulant and it's been much better. Everyone's different, I guess.

So, is Guanfacine ER better than stimulants? I always wondered about the comparison.
