6 ADVERSE REACTIONS The most common adverse reactions reported (greater than 2%) were post-oocyte retrieval pain, abdominal pain, nausea, and ovarian hyperstimulation syndrome. ( 6 ) To report SUSPECTED ADVERSE REACTIONS, contact Ferring Pharmaceuticals Inc. at 1-888-FERRING (1-888-337-7464) or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch . 6.1 Clinical Studies Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. The safety data reflect exposure to ENDOMETRIN in 808 infertile women in a single Assisted Reproductive Technology 10 week clinical study conducted in the U.S. [see Clinical Studies (14)]. ENDOMETRIN was studied at vaginally administered doses of 100 mg twice daily and 100 mg three times daily for 10 weeks and compared to a vaginally administered active comparator. The adverse reactions that occurred at a rate greater than or equal to 2% in either ENDOMETRIN group are summarized in Table 1. Other less common reported adverse reactions in ENDOMETRIN-treated women included vaginal irritation, itching, burning, discomfort, urticaria, and peripheral edema.
