I used telehealth (actually, the nurse practitioner at my doctor's office) once about 30 years ago.
I had a horrific dry hacking cough and nothing was touching it.
The first time I called she sent me to the pharmacy to buy OTC product X. Didn't do *expletive deleted*it.
Called back, she sent me back to buy product Y. Which also did not do *expletive deleted*it.
Called back the next morning, still trying to eject my lungs and rib case through my mouth and she wanted me to go to the pharmacy yet again to buy OTC product Z.
I absolutely lost my *expletive deleted*it, because products X, Y, and Z all had the same useless 'active ingredient' in the same freaking concentration.
I told her in no uncertain terms that it was time to write a freaking prescription for Tessalon Perles. She wasn't too happy about that, and was even less happy when I asked her how much more money I needed to waste on useless products before she'd admit defeat on my behalf.
When I got something similar a couple of years later? Screw the NP. I went to the doc in the box at the local pharmacy. Out in and out in 20 minutes with a prescription for Tessalon Perles and a back up for a narcotic cough syrup for night use.
