OverdoseWell, it happened---the thing I’d decided to bet against when I agreed to try a trial of the drug Tegretol, in an effort to combat the horrible daily headaches that have plagued me for many years. I essentially went into mild Tegretol poisoning. When you start on this drug, which is known most for being an anti-convulsant but which is also prescribed for trigeminal neuralgia (a wicked face pain caused by an irritation of a cranial nerve inside the skull), you start on a low, non-therapeutic dose. You have blood tests often, to make sure your liver is not being affected and that your Tegretol levels remain within a certain range. Gradually, the dose is raised--as long as you’re not having terrible side-effects--until you are taking a dose that is considered safe and one that is holding your pain at bay. With Tegretol, it’s a fine balance. The goal with me was to use the Tegretol to establish the firm diagnosis of trigeminal neuralgia, and then switch to a drug that has comparable results with far fewer side effects. Yesterday I saw my doctor and he upped my dose, since I was only experiencing mild relief from the face pain (mine is actually a stabbing pain in my right eye). I took the first increased dose last night. This morning, before I took my morning dose, I noticed I was twitching. Hands, feet, face, thigh--everywhere. I also noticed I was replacing a word in a spoken sentence with another word which made absolutely NO SENSE. Doug was NOT THRILLED when I told him I planned to fix “newspaper” for dinner. Now, if I’d just been looking at a newspaper, or had just emptied the trash and laid my eyes on a newspaper, it might explain why that word came out of my mouth, but there were no newspapers anywhere. Hmmm. I went ahead and took the morning dose. Four hours passed. I was still twitching and told Doug that my brain was so fuzzy all I could do was crochet a simple pattern. NO WAY could I have driven a car. In fact, when I cut up the onion and potato to put in the crock pot with the newspaper, I mean pork chops, I KNEW I should NOT be using a knife. Around noon, things began deteriorating rapidly. It all started when I stood up. Within a couple of minutes, I was staggering, slurring my words, and finally actually falling on the floor. (Doug caught me not once but twice before I crashed. My hero...) Doug tried to get me into bed, but I knew I had to go to the ER. Fast. The rapid onset of the symptoms was too alarming for me to wait for the doctor to get back from his lunch break before trying to get medical attention. I do not know how Doug got me in the car, especially since he also had to fit all four of him in the driver’s seat. That’s right, four. One of the symptoms of Tegretol poisoning is double vision, but I’m talkin’ quadruple, baby. To only have double vision, I had to keep one eye completely closed---which I did. I remember nothing of the 20-minute ride to the hospital. I do remember telling Doug not to let me fall asleep, because I was pretty sure that wouldn’t be a good thing. He chatted me up the whole time he drove, the sweetie. I also don’t remember much of the first hour we were there. It’s all one big Tegretol poisoning blur. I do know that the Tegretol level in my blood came back at 13.8. A therapeutic level is considered between 4-12. Anything higher than that is just too darned high and can cause the kind of overdose symptoms (and much worse ones) I experienced today. Yikes! So. I’m to skip my dose tonight. (Ya think?) Then take a lower dose for the next few days. Then maybe switch to the other drug that won’t carry these risks, because it looks like we may have hit on a diagnosis. On this intoxicating dose of Tegretol? My head hardly hurts at all!
