The Elavil is not for LPR. I have vocal chord paresis, vagus nerve damage AND LPR. Since I have those 3 things, I was misdiagnosed by many doctors. It took me over 30 years to finally find the doctor who diagnosed me correctly and treated me correctly.
The Elavil is for the nerve damage, which works very well for me, but I still have LPR, therefore still coughing. But when the reflux meds were working, along with the Elavil the cough was gone. I am going to have the Nissen surgery in July, but I will continue with the Elavil.
Good Luck to you and find a doctor that is an expert in LPR and neurogenic cough.
