Neupogen works for about 75% of women. You do a total blood count before you start and then every two weeks. The monitoring is really important particularly if your doing IVIG as well and my dose went from 100mcg (1/3 of a vial) to 60mcg (1/5 of a vial) over the 12 weeks I was on it. Dose is based on weight, immune issues and your total blood count results. My starting dose was particularly high but I am 6ft and 80kg(before pregnancy and 8months of steroids lol!).
Other stuff, you don't take Neupogen the day you do IVIG and it's very important to shop around because I know Sydney prices vary from $1300 to $1600 for 10 vials (aprox 50 shots for the average 60kg woman). Most pharmacies do not stock it and it takes about a week to get in so make sure you reorder in time if you get your BFP on it.
You can't stop taking it till 10 weeks as there is a study where women had to stay on it till at least 9 weeks. You start it just before ovulation and it usually improves your lining even if you had no prob with it. It also appears to improves egg quality if you are taking it in a cycle prior to egg collection.
Ladybug I am sorry for your bfn, it's so crappy. For me I had a failed FET with a PGD embie in feb and my husband convinced me it was like gambling and to give it one more shot on all the same immune meds in March and I am pregnant from an iui, so go figure why my perfect PGD didn't work and an iui with no embie did ? Personally I think the immune meds build up in your system. For me my last PGD embie, and failure on the strong immune meds along with my blood test on my 38 birthday was a really low point but then next month I was incredibly lucky to get a BFP on the same meds. Hopefully your BFP will happen very soon.
Oh I ordered it once from India from medicine+house which was cheaper but he (Atul) is so incredibly unreliable and it ended up in storage so out if the fridge for two days so even though it costs more I would source it in Australia. I am still fighting with Atul.
let me know if there's any other questions that I might be able to answer on Neupogen. I know about 4 ladies who have used it lately and it worked for 3, one got a chemical and is still cycling and one lady it didn't work for even after multiple cycles. Dr M is having some pretty good success with it.
