Hi, I was on vagifem x3 a week for pain, when I started with cystitis symptoms, pain, urgency, frequency, the usual list. After 2 sets of antibiotics I persuaded them to give me ovestin. They would not give me both ovestin and vagifem. I used the ovestin daily for 2 weeks but then could not drop a day without symptoms returning. They therefore allowed me to have it on repeat for daily use. I am now on my third month and am doing well right now with no intention of cutting down. I am also on Evorel 75 patches and utrogestan. If you need longer on daily then you should have it, I believe it says in the instructions to take for at least 2 weeks but maybe more for some.
