Quote from wpmtc:Has anyone taken PREVPAC? This is my second day and I don't think I can take it anymore. I feel sick - severe headache, nausea, horrible taste in my mouth, general overall feeling of beng sick. Is there anything that reduces the side effects? I can't believe I have 12 more days to go.
Your side effects are common, although certainly unpleasant.
A PrevPac is actually a combination of Prevacid and the antibiotics Amoxil and Biaxin.
Biaxin is most likely causing most of your problems-- many people experience nausea and a metallic taste in the mouth while taking it.
As far as foods, grapefruit can interact with the Prevacid and Biaxin.
