Confidence Intervals for Geometric Means

I have some data where I need to get the geometric mean and its confidence intervals. Since Proc Means doesn't do geometric means, I've been taking the log of the data, getting the mean, and then taking the anti-log. However, that doesn't give me the proper CIs. Does anyone have any helpful tips?

Thanks,
Meredith
