I went to an inadvertently self-imposed hell last week. Partly it is the danger of knowing a little too much medicine in another field and partly just accident.
Okay, I have what doctors call a Poly-Pharmacy Syndrome. It seems like I march through life adding on new meds right and left. I've heard you guys talk about it, too. A new symptom here or there and there is a twinkly new drug to catch our eye and add to the medicine dispensers. Ohhhh, a another new symptom and another new med. There is so much twinkling going on that my medicine box glows in the dark. I would welcome Tinker Bell at this point.
Well, to our credit we do often ask what all these meds are doing to us and whether any of our symptoms are not MS, but rather side effects of a toxic medicinal regime. I do this less than most because I do have a passing knowledge of basic pharmacology, have handed out my share of scripts and was raised in a household where my father felt that, not only was there a pill for all ailments, but more is better than less. Now, in his elder years, we have had some medical emergencies arrising from his tendency to take pills by the handfull - aspirin, potassium, codeine, acetominophen.
So, I periodically go through my meds to see if there are any I can do without. I have come off sleeping meds, extra anti-depressants, meds for vertigo, ....the point here being that I have tried to keep the glow of glittery medicines down so we are not raided for being a pot-growing house in suburbia.
Recently it came to me that I had not had twinges of the Trigeminal Neuralgia for many months. That is why I take the Tegretol (carbamazepine). Last year I tried to stop it and the twinges returned. But, it is worth another try. So, I began very slowly decreasing it. I told my neuro about it who was okay, but said to restart it at the FIRST tweak of pain. I came off of it a couple weeks ago.
Now, this has not been a great summer for me - better and worse than some of you. The complete urinary incontinence has settled into what is "just my life". I'm no longer totally aggravated by the constant purchase and use of the products and the 10 visits to the loo daily, plus the carrying around of an overnight bag with incontinences products, at least two changes in clothes and clean up supplies. It just is the way things are. The med, Oxybutynin helps with the Epic Floods. I mop floors only about twice a week now instead of twice a day. THAT was really aggravating. And the usual side effects from such a med - even doubled - were minimal. Not much of a dry mouth nor much constipation. This was a sparkle from the med box that I didn't mind.
Suddenly, I was sick. Indescribably sick - literally - I couldn't describe it. My whole head was about to crack open, my skin felt tight and hot, yet the movement of air from a fan was horridly painful and uncomfortable. I was nauseated. My head roared. I was unsteady and dizzy - really unclear where the ground was or exactly how the ground met the wall. Chest pressure - not pushing in, but pushing out.
I recognized this. These were the same symptoms I had on even the normal dose of Detrol LA. But, I had been tolerating the Oxy at double dose for a couple months. The symptoms seemed systemic - all through my body - and not so much neurological. I stopped the second dose of Oxy, but didn't feel better. Nothing felt good and nothing helped. I stopped the Oxy completely.
Over about four days the horrid sense that I was dying of jungle rot or something similarly evil disappeared. And the flooding returned. The 3am moppings to save the hardwood floor, washing loads and loads of laundry. And the mice returned. As some of you might remember, several sad mice died in the floods of the springtime. Tony, our lazy, lovable lummox brought in his hunting prize one morning just before dawn. It was great fun tossing it into the air and catching it on the way down. Yes, the association between mice and incontinence was real. And then in great cat fashion, he presented me with his prize in my recliner.
I have no intention of becoming a Mouse POW camp. Tony had not even taken the courtesy of killing the mouse first. Little field mice have very tiny and soft feet, but the scurrying roused a primitive "scoot-away reflex" and that is impossible in a recliner. I turned on the light, and flicked the critter away, while yelling at Tony. Tony, is a heedless big guy who responds not at all to scolding. He's sort of like your college roommate who walked around in his boxer shorts and drank beer for breakfast. As you scold and yell he looks lovingly up at you and says, "Hi, Mom!"
Miraculously, the symptoms went away as the Oxy got out of my system - and curiously, we haven't had a mouse since then either. Since I could think again I tried to sort out what had happened.
Now, this is what I want all of you to know about. And, yes, somehow the mouse story seemed pertinent.
When the pharmacist checks for drug interactions, I wonder if most of us know what that means. The most common interaction is that one med affects how well another med works. Like a med containing calcium (TUMS) will render some antibiotics (Erythromycin and others in its class) completely useless because they bind together in the stomach and are pooped out together.
Well, there is another way and it is not important that you understand exactly what happens, but it can play REAL havoc with your meds.
Tegretol is metabolized in the liver. It also "induces" or rev's up a set of enzymes in the liver that can metabolize other meds faster. Its called the P450 system. So if you take a medication that is handled and metabolized by the P450 system, your levels will drop of that other med while you take Tegretol. That other med may appear to lose its effectiveness.
So, you guessed it. Oxybutynin is metabolized by the P450 system. If the P450 system is all rev'ed up, then Oxy will be elimated from the body faster. So, I have been on a good hefty dose of Tegretol for about two years now. I start Oxy and it doesn't work too well in the regular, 24-hour single dose. So I step up and take it every 12 hours. I tell all my doctors and no one seems to think this is out of the ordinary. Another member here also mentioned that he was on the double dose also. Makes sense. People often respond to meds at different doses than other people.
Soooo, I dropped the level of the Tegretol to zip. None there and after a few days the P450 system no longer has something driving it to work in hyperdrive. The double Oxy dose is no longer whizzed out of the body so fast and the level becomes toxic - and I feel like I'am going to die. I stop the Oxy and the mice show up. The little mysteries in life start making sense.
