asthma
"I was prescribed this for asthma.  I suffer from really bad cedar fever which is a problem in Texas.  I am a rather slim female and at first my doctor gave me the regular adult dosage.  It was too strong.  I had heart palpitations and almost called 911 once after taking it.  I requested my doctor give me an adolescents strength dosage - which he did.  That worked much better.  It still is a very strong and it knocked me out, but I didn't have to worry about calling 911 or not waking up from it.  Asthma is tough to treat.  Medicine is necessary, but sometimes the meds are as bad as the disease.  My advice is to start with the lowest dosage your doctor thinks will work.  You can always take more if necessary."
