I have also had hiccups after cortisone shots. I tried the q tips and it helped a little, but I found that the peanut butter worked best for me so far. I didn't have to eat alot at one time, I just took a large eating spoon and dipped it into th epeanut butter jar and got about 1/2 of the spoon full of peanut butter...then I put some honey on it and ate it sloly lie you would ice cream. Hiccups stopped. I went to be then two hrs later they started again. Repeated the same thing and they stopped for the rest of the night.

Earlier in the day at work I had some hiccups and ate some pepcid and that helped too.
