Ask your doctor and/or ask a pharmacist. My Target pharmacist walked with me over to the over the counter 'cold' products. First he asked what I was taking then next he asked what symptoms do I have and he doesn't want to give multi symptom med-- just for your specific symptoms.
He asked,---my age ( I'm a senior).
- stuffy nose, runny nose, coughing, temperature ( how high), breathing problem shortness of breath, nausea, vomiting, loss of appetite, chills , taking any pain med like aspirin, aleve, Advil. He ended up suggesting a call to my doctors office. He was giving me his best advice and I decided to take it.
(Of course you can still purchase OTC products but I felt he spent time to assess what I told him and he gave me his professional opinion. ). Gregory, there are lots of things to consider when one has reflux. Hope you get better and it's not the bad flu. The doc can help there too.
