I'll explain a little more detail and it should clarify a couple of things (why they assumed I was taking the medications 3x/day and why possibly they aren't giving me anything more for Chronic Obstructive Pulmonary Disease (COPD), although I'm only speculating that part since reading your informative answers).
I used to get bronchitis once or twice a year and go crawling to my dr after letting it get so bad that I was completely miserable. My regular dr just treated it as bronchitis and I'd get over it and move on. Then I went in once and had to see a different dr and she, being new and unfamiliar with me, read thru my file and noticed a seasonal pattern to when I was coming in with bronchitis. She gave me antibiotics for the bronchitis but also told me she thought it was allergies instigating this, due to the seasonal pattern, and because I smoke my body had a harder time ridding itself of the congestion. She urged me to just try allegra-d after that bout with bronchitis was over. I did and could breath much easier, slept better, and my smoker's cough went away. She told me I could stay on allegra-d long-term and it could very well prolong time before I developed other long term effects from smoking because it would help my body get congestion out. Also, I think since that time, which was about 5 years ago, I've only had bronchitis once or twice. That rx she gave me was for one allegra-d each morning but I could take a second one in the evening if needed. I only took a second one on very rare occasions, like if I'd cleaned the dusty yard shed out that day and my sinuses clogged up.
Fast forward to being unemployed, not having medication insurance, and my rx for allegra-d running out, and ending up going a few months trying to survive sinus headaches by taking OTC allergy medications that did absolutely no good for me, then finally getting medication care from VA last summer-
At my first appointment with VA last summer, I explained all this and was told they don't rx allegra-d, they only rx what they keep in stock because they mail out medications usually (not always). So, they rx'd an antihistamine and the psueodo(????) stuff that is the decongestant. They explained to me that taking one of each would be the equivalent of taking one allegra-d. Fine, so that's what I've been taking (one of each per day). I never read the rx because, well, I figured I already knew everything I needed to as far as when and how often I should take this. What came to light yesterday is that the rx said to take the pseudo(???) every 8 hours, which would be 3x/day, so they assumed I was actually taking it that much. I had never even noticed that it said that believe it or not. They are pretty good with record keeping and coordination between various medication depts so they can easily verify how often I have called in asking for a refill and figure out that it would equate to taking one medication per day, not 3 times as much.
The rx for 3x/day probably happened this way (just speculating)- the licensed md who came in yesterday said that they would never rx 3x/day for long term use and that's why they wanted to take me off of this. She said they rx that dose if a person is already very sick and they need this much for a few weeks to get past a bout of severe sinus congestion. So I assume that when I came in last summer complaining about my head feeling like it was going to explode and that it had felt that way for weeks, the intern got approval from the dr for the rx and they wrote the rx for the higher dose. Then, after I get my old medication records to them and explained all previous stuff, they agreed to write the rx allowing refills for long term use but they never went back and reviewed the dose rx'd so it was still in their system as 3x/day, and thus, they made an assumption. Once I explained to them yesterday that it wouldn't have mattered to me even if I had read the rx for 3x/day, I wouldn't have taken it that much because I knew that 1x/day was sufficient, the licensed dr said it all added up now and what I was saying sounded right so I could stay on it long term and she told the intern to change what the rx says in their computer to 1x/day.
So, going back to Chronic Obstructive Pulmonary Disease (COPD), I assume that taking this decongestant and antihistamine daily is preventing the need for more serious medications, at least for the time period. At some point in time I guess it's likely this won't be enough anymore and then we'll have to discuss options for whatever problems I'm having then. Would that sound like a reasonable speculation, based on your all's experience and knowledge about Chronic Obstructive Pulmonary Disease (COPD)?
And as far as paying for it, it was covered by them when I was unemployed and had no money because I am a veteran and the law had changed allowing vets to get care at VA under those circumstances. Now, I can still get medication care there but since I now have a job and medication insurance, it works just like it does with any other medication care provider. Insurance covers part and I have a copay. I could obviously switch to a private provider now but am choosing not to until I have a more stable job that I can count on lasting longer than this one, just in case I end up in the same boat I was in last year again.
