At my current dosage, I get almost six months' worth for fifty bucks at the local AIDS-serving pharmacy. The price includes needles. I didn't get any alcohol wipes last time, but I thought they were included the previous time...still, wipes are cheap, a few bucks a box. For each injection, I use one wipe for the vial and one for me. So it all adds up to a little over a hundred bucks a year. When I was at a higher dosage, I still paid less than $150 a year.
I also use a tissue and a little dot Band-Aid for each injection. The price is negligible, a few bucks a year.
This is all out of pocket, of course. Insurance prices are usually cheaper.
