Levaquin Leva-Pak and care doctor

An Urgent Care doctor perscribed this to my 16 year old son. We do trust our doctors, but apparently this is NOT to be given to minors. After ONLY the 2 pill, my son could not hardly speak, his jaw was so so crooked, I thought he was having a stroke! He was so petrified and it truly was the most horrble thing we have ever gone through. We rushed him to ER and the doctor could not beleive that the perscribed this to a 16 year old, and that Rite Aid filled this prescription! Never would I recommend this. The ER doctor said as soon as it was out of my sons system he would be okay, and recommended Benadryl. After the first dose of Benadryl, he was okay and this drug was out of his system in about 2 days. Another terrible side effect was his face would not stop twitching. AWEFUL.
