Is it possible for prenatal vitamins to cause headaches?

At first I was blaming my headaches on the heat and not drinking enough water throughout the day but I seem to be getting headaches almost every day. Is it possible that the prenatal vitamins are causing them?

Re: Is it possible for prenatal vitamins to cause headaches?

I think anything is possible with pre-natals. The most common one I hear is that they make people nauseous (did with me). But it is possible that they give other people headaches. I would talk to your doctor about it to see if they have a different brand they can recommend/prescribe. Also, I am guessing by your name/number of posts you are newly pregnant and/or in hiding. I would also make sure that you aren't having caffeine withdrawals. I BARELY drank coffee, just one (big) cup in the morning and I still had 2 week caffeine withdrawal. I hit the soda aisle and picked up the little 8oz cans of coke and would drink one of those if I had a REALLY bad headache. It wouldn't get rid of the headache, but it did help!
