This is way, way off-topic, but I'm posting in case anyone has experience in this area.

We've had a medication snafu with Jimmy.

I was trying to boil the med snafu down to one sentence, but now that I've surfed some web sites I see that boiling it down isn't working.

As briefly as I can put it:

• Depakote is an anticonvulsant Jimmy takes to control a very mild seizure disorder.
  
• To work, Depakote has to be maintained at a certain level in the blood.
• Jimmy takes one dose of Depakote a day, always at bedtime.
  

The snafu:

• Last night Ed discovered he had probably given Jimmy his nighttime dose of Depakote that morning by mistake (we were out of town, pill box was turned upside down in suitcase, etc.)
  
• At that point we decided to skip his bedtime meds because he'd already taken them that morning.
  

So here's the question.

What should we have done?

And what should we do now?

I just picked Jimmy up from school, where he fell asleep during speech therapy and couldn't be aroused. Then, in the nurse's office, he woke up, "fell asleep," woke up again, fell asleep again, etc. His behavior was pretty close to what you'd call passing out, not falling asleep.

He's acting fine now.

The nurse says her intuition is that, in the case of Depakote, it's probably better to overshoot than to undershoot, but she doesn't know.

Does anyone have experience with this?

We've emailed his doctor, so we'll have professional advice shortly. But if anyone has experience or knowledge I'd like to get it.

Thanks!
