Letrozole THEN Clomid?

Hi all - anyone move from Letrozole to Clomid? I usually hear of the reverse. I have been happy with (no side effects) and responded fine to Letrozole so far, but my nurse suggested thinking about moving to Clomid. Frankly, I'd be a little nervous from what I hear about Clomid side effects! Thanks for any input.
Me: 33, PCOS with anovulation
DH: 36, No known issues
TTC since 11/2014
1000mg Metformin daily

Oct-Dec 2015: Letrozole 5mg, Ovidrel, TI = BFN x 2
Feb-May 2016: Letrozole 5mg, Ovidrel, TI, Prometrium = BFN x 3
August 2016: Clomid 100mg no response, Letrozole 5mg, Ovidrel, TI, Prometrium = BFN

Re: Letrozole THEN Clomid?

  • I've always heard of it done in the reverse as well. At least that's how it was for me. What has your dr said? Are you seeing an RE?

  • You should ask your RE for a reason why. I switched from clomid to letrozole because I had a thin lining and some odd side effects on clomid. I did have a better response on the clomid with more mature follicles though.

  • @LizzieJ13 I'm wondering her reasoning behind that?? I did several rounds of clomid before switching to Femara. Everyone's different hopefully you'll have a great response to it, I didnt
  • My RE is switching me from letrozole to clomid this next cycle as well...I've taken letrozole the last 5 cycles with okay response...so my RE wants to see how my body responses to clomid....I'm excited...letrozole isn't doing it for me
  • Thanks everyone. Yes, I am seeing an RE. The nurse asked me if I was interested in switching, since this will be my 4th round of Letrozole. I asked if my response hadn't been good enough and she said no it's been fine. I think they're just trying to switch it up since I'm not doing IUI or IVF so they want to exhaust all options for meds. 

    @LMart85 , what do you mean by an OK response? I've only had 1 follicle each time, maybe they'd like more? My thought is, if an u/s confirms a good-sized follicle and then ovulation is confirmed with a blood test, how would Clomid be different? I am so afraid of mood swings that I think I'm going to stick with Letrozole but I am definitely to interested to hear other experiences.

  • When I took letrozole, I only had 1 mature follicle except for 1 month I had 2. My RE would like to see 2 maybe 3 mature follices for a better chance. So if it helps get me pregnant, I'm all for the clomid!
  • Ah I see. Please update on how the Clomid works for you! I would definitely like to have 2 follicles so maybe it is worth considering.
