I was taken this medication for my sinus infection also along with an antibotic. I felt very odd when I took this medication - I experienced a feeling of hyperness. I found out that this medication caused my heart to speed up, causing me to have an anxiety attack. I have been advised not take this medication anymore by my physician.
I am very sorry that this has happen. Your son must get the drug out of his body. One of the side effects of this drug is anxiety. Which is a Genralized term used for panic attacks,depression and many other mental ailments. The drug is still in his body and he must detox to rid his body of this medication which is bascially poisoning his body. Causing these symptoms. Please note I am not a doctor nor any medical care giver. I am only a independent researcher. Here are the names of to medical care providers that can help you. If they are not in your area they will help you locate someone who is in your area.
