We've only been through one IVF cycle, and used the pharmacy that my fertility center recommended (Freedom Fertility). The total cost for my meds for the first cycle was ~$3900, after insurance covered a portion of a few drugs and brought the cost down from the initial ~$4200 estimate Freedom gave us. The cost breakdown for each of the meds was as follows:
Endometrin suppositories (3 x 21 suppositories, or 3 wks worth) - $45.00 copay
Estradiol tablets - $9.60 copay
Azithromycin - $6.70 copay
Novarel - $67.00 copay
Menopur (15 vials) - $1103.50 copay
Gonal-F RFF pen (5 or 6 pens; can't quite remember) - $2085.00
Ganirelix (5 pre-filled syringes, I think) - $599.50
The expensive drugs - the Menopur and Gonal-F - are the injectibles that were used to stimulate the production of multiple follicles/eggs. The Ganirelix was used in combination with those to prevent premature ovulation before the trigger. The rest of the meds (the cheaper ones!) include the trigger shot (Novarel), the antibiotic taken prior to egg retrieval, and the progesterone/estrogen support for the endometrial lining following egg retrieval and through the pregnancy test/early pregnancy.
I hope the information is at least a little helpful for you, but more than that I hope you won't need to go the IVF route at all! Good luck as you continue TTC over the next few months.
