I recently started my 10-year-old son on Guanfacine ER 3mg Tablets to treat his ADHD symptoms. The medication has been a game-changer for us. Guanfacine ER is an extended-release tablet, so he only has to take it once a day. This has made our mornings much less hectic. I've noticed a significant improvement in his focus and a reduction in his hyperactivity and impulsive behavior. However, I've also observed some side effects, particularly drowsiness and fatigue. My son's doctor assured me these are common and should subside over time. I'm curious to hear from other parents about their experiences with this medication. Have your kids experienced similar side effects? How long did they last? Any tips for managing them?

I've been on Guanfacine ER for a few months now, and it's been a mixed bag. The focus improvement is great, but the dizziness can be pretty intense sometimes. I've had to be careful standing up too quickly. Also, the dry mouth is awful. My doctor suggested drinking plenty of water and using sugar-free candy to help. It's worked okay, but I still deal with it. I hope the side effects pass for your son.

I've heard mixed things about Guanfacine ER. Some people swear by it, others say it's not worth it. Guess it just depends on the individual. Just make sure to keep a close eye on the side effects. They can be harsh.

Is it worth mentioning that this medication is an extended-release tablet? That means it's designed to release the medicine slowly over time, so you only need to take it once a day. It's a big plus if your kid struggles with multiple medications throughout the day.

As someone who also takes this medication, I can confirm that the side effects can be tough at first. I remember the first few weeks were a nightmare with drowsiness and dizziness. But after a while, my body got used to it, and now I'm doing great. Just give it some time and talk to your doctor about managing the side effects.

My son tried this medication and unfortunately didn't tolerate it well. He experienced severe stomach pain and vomiting. We had to switch to something else. It's a bummer because it did seem to help with his ADHD symptoms. Definitely talk to your doctor if you notice any severe side effects like that.

This medication has been a lifesaver for my daughter. She's been on it for about 6 months now. The only noticeable side effect has been some irritability, but it's much better than the constant chaos we had before. We've also noticed she needs less sleep than before.

Wow, didn't realize this medication could have such severe side effects. Always remember to contact your doctor if you notice any of the urgent symptoms listed in the original post. I'm glad it’s working for your son, but definitely keep an eye on those potential issues.

Yes, absolutely. I've found that it helps to give it with food. My son is less likely to experience stomach issues when he takes it with a meal. Always worth a try if your experience similar issues. Also, sleep problems and issues with appetite are different for every child, and may only be temporary.

Glad to hear you're seeing some positive results! My daughter was on Guanfacine ER, and it really helped with her impulsivity. We did experience some drowsiness at first, but it got better after a few weeks.
