Sensitivity to Drug Side Effects Increased by Migraine Attack
Nine days of dizziness following four days of migraine. That’s what I’ve been up to these last two weeks.
The migraines made sense. We had rainstorms that week and I’d blown off my diet a couple times. The dizziness, however, was surprising. Wellbutrin has been to blame every time I’ve been dizzy in the last 16 months, but it didn’t make sense. I haven’t changed my dose in a few months months. I’d eaten plenty before taking it each time and hadn’t missed a dose. Maybe I accidentally took too much one day? I skipped a dose intentionally, took it at different times, took 300 mg instead of 450 mg. When the dizziness did lessen, the reprieve never lasted long. It was as if the migraine attack had made me more sensitive to Wellbutrin’s side effects.
It seemed unlikely that one migraine attack would change how I reacted to medication I’ve been on for more than a year, but my headache specialist told me he’s seen it happen with other patients. As he put it, the brain you have after a migraine attacks is not the same brain as you had before it. Any medication that acts on the central nervous system, like antidepressants, could interact with this new brain in a different way than before, causing an increase in side effects. My dose hadn’t changed, my brain had.
The changes to your brain after an attack are not permanent, so please don’t let this scare you. It’s more like a storm with high winds came through and there’s still dirt and debris in the street. The street sweeper will get to it eventually, but it may take some time. (I live in a place with haboobs and dramatic thunderstorms. You can liken it to a snowstorm if that’s more familiar.)
I’ve been taking 300 mg of Wellbutrin for the last week. Today I can look at the computer without feeling like my head is melting as if in a psychedelic video, but I still have to be careful to minimize the chance of side effects whenever I take a dose. My fingers are crossed that this part of the change to my brain lasts and that I can keep the depression at bay on this lower dose.
My naturopath/therapist believes that my depression is directly tied to migraine attacks. Since I started seeing her almost two years ago, every increase in depression has followed a long migraine attack that didn’t respond to acute medications. This fits with my headache specialist’s explanation. I haven’t waited to see if the depression abates without medication, but I wonder if it would. Not enough to find out, but I will ponder it.
My fingers are crossed that I have the internal mess from this latest storm cleaned up. Now it’s time to attend to everything I haven’t been able to attend to while weathering it. I’m going to read and approve a slew of comments now, but it will take me a while to respond to all of them.
