Any IVF'ers out there use the Follistim Pen? I am a major stress case this morning over the damn thing.
The instructions on using it are clear enough - dial the dosage needed, insert needle and push plunger all the way to zero. Zero means you have given yourself the correct dosage. If there is not enough medicine left in the cartridge for your full dosage, it will stop before zero, and the number it stops on is the amount you need to give yourself out of the next cartridge.
Simple enough.
Now, as much as I am crazy busy and have tons going on right now, my drug regimen is not something I am haphazard about. I am meticulous with the medications, because in the grand scheme of everything this is the only thing that matters right now.
So, imagine my surprise.
My instructions were to give myself 225 units of Follistim on Saturday, Sunday and Monday. Knowing ahead of time that there are only 600 units of medicine in each cartridge, I knew that on Monday night I would need to administer two shots because there would only be 150 units left in the original cartridge.
So, as usual I dialed the pen to 225. I wanted to see it stop on 75 like it was supposed to. I pushed the plunger in and it kept going and going and going - all the way to zero.
I swear, I sat there silently staring at my injection site for twenty minutes. "What do I do? What do I do?" Anthony was as dumbfounded as I was.
"Are you sure you dialed it right tonight?" he asked.
"Positive."
"Are you sure you gave yourself the right amount the last two nights?"
"Anthony," I said, trying to stay calm, "this is the ONLY thing I am certain about. I am doing my meds correctly, I know I am."
After much debate, I decided to still go ahead and give myself an additional 75 units. I cannot understand or explain the behavior of the pen, but bottom line I know that a cartridge only contains 600 units and that after 3 nights I should have administrated 675 units. In equal doses every night, but apparently I have no way of knowing whether this happened or not.
I am very, very stressed out. I wanted to ensure that I got the right amount of meds last night, but what if in fact I wound up giving myself 75 units too many?
I guess that is why they monitor my blood work so closely. I am on my way to the clinic now, in fact. Let's see what they say.
Update: Thank all of you for your comments. The nurse told me the same thing you all told me, that the cartridges are overfilled with medicine. It really, really would have been nice to know that ahead of time. Here I thought this whole process was so precise and scientific! Anyways, I did indeed take 75 IU's too many, but they made a note of that in my chart. When they called in the afternoon with instructions, the nurse said everything was looking "perfect" and that I should stop worrying, she reassured me that the mistake I made has no bearing because everything looks good. So...that is reassuring.
