I Have A Nine Year Old Granddaughter Who Is An

I have a nine year old granddaughter who is an asthmatic and is on oh dear I can't think of the pump med oh its ventellen
And also takes phenergen, her asthma became worse, she also has developed a sore throat and has been getting ulcers in her mouth...She has had almost every blood test and an ultra sound on her throat and all results are good.... Decided to look up phenergen side effects and see her symptoms are listed. I will advise her parents to look same up and probably cease this medication.... She does suffer from hay fever hence the phenergen.... What other suitable medication would you suggest to replace this.. ?
