I went to the emergency room last night. I was severely dehydrated, I have the flu and an intestinal virus. The doctor prescribed me Tamiflu, but I'm scared to take it. It's a category C product, not tested on pregnant women, but their website states "TAMIFLU is normally not recommended for use during pregnancy or nursing, as the effects on the unborn child or nursing infant are unknown" and "FDA pregnancy category C. This medication may be harmful to an unborn baby." But my doctor tells me he recommends I take it, so I don't get worse...What should I do?
