I take 60 mg twice a day for endometrial bleeding. I am 28 years old. I had a biopsy done two weeks ago. Which caused heavy bleeding, so they increased my dosage to 80 mg twice a day. I started getting nauseous and dizzy with stomach pain. I almost passed out at work. The doctor said Megace does not cause dizziness or nausea. I had the same symptoms on liquid Megace and had to take over the counter medication to help.
