This is the same stuff I bought and use:
bpatters, I use the same syringes shown in the pictures at the above link.

You said you were using a .5cc insulin syringe, which will have different markings. Insulin syringes are marked in units, not necessarily in ccs.
You need to be sure you're not giving half the recommended dosage.
Somewhere on the box (or perhaps in the directions) it should have the actual concentration in mg/ml. The Durvet pour-on ivermectin I have doesn't use the percent method (which can be misleading and end up with people giving less than they should). It does only say "Contains 5 mg ivermectin per mL" which is the clearest method of describing the concentration.
I do understand this was not easily evident on the Ivomec box.
Just make sure you understand there are 10mg/ml. That is the concentration (people, please, correct me if I'm wrong).
1 unit of U-100 insulin is 0.01 ml in a regular syringe Read more at: https://tr.im/NptLf

U-100 insulin syringe on left vs generic 1cc syringe on right. black lines indicate 5 units "insulin" on left & 0.5 cc on right. I'm not seeing a big difference in pic. If I'm reading the link correctly (my eye sight is at about 20% today) I've actually been dosing them with slightly more than recommended on GL calculator.

Don't kill yourself unless you really, really hate math. ;-)
1% is 1 in 100 of something (anything). That means that 1 gram of ivermectin is mixed in 100 grams of carrier.
The tricky part to remember is that the density of water is 1 g/mL, or one gram per milliliter. Most water-like substances are about the same, so now you'd have 1 gram of ivermectin in 100 milliliters of water(ish stuff).
There's 1000 mg in one gram, so now you have 1000 mg of ivermectin in 100 milliliters of water(ish stuff) = 10 mg/mL.
Wasn't that fun? :-)
Peek is scheduled for a re-check on Monday. If she still can't figure out what his problem is, I'll take Peek AND Fuzz up to Lacey to see the vet at The Farmhouse.
Also, he's decided the Metacam is SO delicious he jerked the syringe out of my hand and took off with it. I had to chase him down and take it back! (He takes it so easily any more, I've just been leaning down with the syringe and let him smell it, before he opens wide. I won't be doing that anymore!)

That's happened multiple times at our house. Actually, don't worry about it because usually they drag it into a hide and drop it. They won't hurt themselves with it -- at least none of ours ever have. Just pick the hide up and retrieve the syringe, and give the med to the pig if he didn't already get it.
It's enormously useful when they like the meds (Metacam is usually readily taken at our house, too). Saves an awful lot of time and hassle having to chase them down and pick them up.
We also hear you on the lettuces. We usually feed redleaf and greenleaf primarily, because we too have had a lot of trouble with romaine. The quality here (metro Atlanta) has been dismal, too.
