I am 53 and have been having a very heavy cycle every 3 months. Last time my cycle was light for 30+ days and then extremely heavy. My doctor gave me samples of Lysteda, I took 3 x day for 2 days, and my bleeding stopped. The next cycle was 3 months later and very light for 7 days. Two weeks later, and I am now flooding again. I took 2 doses of Lysteda so I could work, and the flow is much lighter. Unfortunately I have now had a horrible headache for the last 4 hours. Is Lysteda safe at my age?
