Medication can be helpful for some behaviors that may be related to ADD or ADHD but you should consult with your family physician and likely also consult a child psychologist before taking any action. The teacher may have some knowledge but it is not their area of expertise. If you would like to seek out the possibility of medication than write out whatever questions you have and take them to the doctor or psychologist and they will be able to help address your concerns. Medications also have different effects on different individuals so if you do decide to get him medicated, it will be important to observe him closely and see how the medication effects him. Pairing medication with counseling has consistently been found to be the most effective way to treat any problem like this.
If you do not want to get your child medicated, that is your perogative. Instead you may want to seek out other sort of help for your child to learn more appropriate social skills in the classroom and to control their impulses. Sometimes this can be done in a counseling setting or in special educational groups for children which are intended to help them learn to focus. These can be effective as well.
We hope you can gather more information regarding this and make a decision that you and your family are comfortable with. Please take care!
