I took my first injection doses of menopur and follistim last night and I felt dizzy for two hours and have had a killer headache ever since. I called my doctor, and he thinks it is from the menopur... he suggested that I tripple the dose of the follistim and not take the menopur. He said they are basically interchangeable. Has this happened to anyone? Is dizziness and tightness of the chest a typical side effect of menopur? Thanks!!
