For Progesterone Insufficiency "I'm pregnant and my lab work came back indicating I have a low progesterone level. My doctor prescribed Prometrium and initially I took the medication in the daytime, but then found that it makes me extremely tired. I decided to start taking the medicine at bedtime then started having very bizarre dreams only when I take the medication at bedtime. I informed my doctor, but he dismissed the side effect as not being related. I'm positive the side effect is from the medication. I hope this comment lets other women who experience this side effect know that you are not alone. Just because it's not a listed side effect doesn't mean it can't happen."

For Perimenopausal Symptoms "Taking it at 100 mg. Didn't like the dizzy feeling. Started taking it at night, much better, but I feel it building up in my system over time. I wish I could take half or 3/4 as much, but it is not available in those doses. I have absorption issues, and the liquid form is great except I can't cut it in half. I do like what it does for my thinking, digestion, emotions, etc., but over time, irritability, heavy dreaming, pregnant-like feeling build up. I am a small woman, about 110 lbs, 5 feet, and wish smaller doses were available. A little bit goes a long way."

For Uterine Bleeding "I am on 200 mg Prometrium due to uterus bleeding and enlarged uterus wall. Other than the bleeding, I had no post-menopause issues (I am 57 with high estrogen levels). After 2 days of taking the medication, bleeding stopped - great! After a few more days, I started gaining weight, breast tenderness, breast enlarging, very strange dreams every night, very tired during the day although I sleep at least 8 hours now, and bad headaches. Too many side effects for me. I went to my naturopathic doctor to do detailed hormone tests. Result = extremely high progesterone level. Make sure you get your hormones tested before taking the medication!"

For Progesterone Insufficiency "I am 46. I am estrogen dominant and have low progesterone. I also have PCOS. I take 100 mg after menstrual bleeding, 200 mg upon ovulation, and none when bleeding starts. My periods were abnormal (cycle 25-36). I take it by mouth at night and go straight to bed as it makes me extremely drowsy. If I try to stay up, I have lucid dreams. Some tiny stomach cramps but not bad. Breast tenderness has drastically decreased. Some left shoulder pain. Not sure if that has anything to do with the medication. Since starting break-through spotting during ovulation and a short window between ovulation and period. Cycle is currently now at 20 days. I have read this can happen but can’t find a lot of reviews on it. Not sure if that is normal and will be following up. Facial hair growth appears to have decreased."

For Progesterone Insufficiency "I am on a 100 mg dose, days 14-28 of my period or the first 12 weeks of pregnancy. The first month was great, I felt level. The only side effects felt were extreme sugar cravings and vivid, bizarre dreams. However, in month two, no cravings, extreme mood swings, and ranging from a need for a lot of sleep, not wanting to get out of bed, to anxiety and very little sleep. No pregnancy yet."
