Hi Michael,
Ribavirin should be taken with food. I tried without when I wasn’t hungry on peg/riba treatment and became quite nauseous, after that I always made sure I ate something with it.
Here you go, page three, half way down left column:

Edit: as Paul points out below, the food should have some fat in it. I changed to full cream milk on my cereal and if the evening meal is fat free I have some cheese and biscuits with the riba.
