What is the main difference in use?

How the insert goes in. Imvexxy is a small insert placed smaller end up, about two inches deep.1 Vagifem comes loaded in a disposable applicator that is pushed in gently, no further than comfortable, and the plunger releases the insert.2 The schedules are the same shape: daily for 2 weeks, then twice a week.12

How do the side-effect numbers compare?

Imvexxy's 12-week trial found headache as the only side effect in at least 3% of women and more often than on placebo.1 Vagifem's 12-month trial lists vaginal yeast infection, itching, back pain and diarrhea more often than placebo.2 These numbers come from separate trials with different people, lengths and methods, so they are not a head-to-head comparison.
