If for some reason you no longer have the data sheets from the pharmacy, you can go to the library and look the drug up in the PDR (Physician's Desk Reference) which will give you all of the requisite data on any medication available, albeit,, not generally in laymans terms.....
Trust me, doc, sir, I am so leery of these things I have all paperwork associated with them. In my opinion, or perception, or observation based upon past experiences with others, this is dynamite here--necessary dynamite--and needs to be handled with as much caution and care possible. Knowledge is power.
But none of the instruction sheets deal with dehydration.
I'm going to play a primitive here, and boast about the specific pharmaceuticals; it's no hair off my ass anyway, because the plan is, after stabilization, to work to get off of these things. Especially, as my primary physician, the dermatologist, says, I'm in really bad trouble if I go out into the sun too much with this in me. I'm in enough trouble as it is, without these chemicals in me.
At the hospital, in the emergency room, the physician was going to prescribe me a whole array of drugs, including pain-killers (even though I was in no pain), until I made noise about it, and told her we needed to go mild, as mild as possible, on this.
So we talked about it, and she tore everything up, and ordered me only Metoprolol Tartate 50 mg, one tablet two times a day.
That was Sunday night; Monday early afternoon, another physician said no, that wasn't nearly enough, that wasn't going to cut it. He started writing down a whole lot of things, to which I said, whoa-ho, mild it down. My body has a history of healing on its own, and even if it takes longer, I'd just as soon heal naturally as much as is possible.
So he tore everything up, and ordered me only Lisinopril-HCTZ 12.5 mg, one tablet one time a day.
In my whole adult life, other than occasional penicillin, these are the only pharmaceutical drugs I've ever taken. Every time I've broken bones, physicians have prescribed pain-killers, but those pieces of paper went into the wastebasket upon leaving the hospital, or arriving home.
I some days ago read all the small print regarding the two pharmaceuticals, whose primary side-effects appear to be loose bowels, which has not happened in six days, since I first started taking them. But then and again, not being a primitive, too-loose or too-tight bowels has never been a problem. As Sigmund Freud reminds us, excepting in the case of women bearing infants, bowel disorders are a result of malfunctioning attitudes about people and life.
