It took out endo about a year to warm up to the idea of going to the pill format. Intitially, she wanted us to keep the liquid on hand for smaller doses and we never have. We have had the phamacist make the suspension for us and it was just fine. They got the recipe from Upjohn, I beleive. this was during a time when Upjohn ran out of suspension. They have a great track record, huh??
