It's not just stigma with thalidomide - the two forms of the molecule interconvert in the body. So even a dose of 100% pure R-thalidomide (the useful kind) will invert into its mirror image, L-thalidomide (the harmful kind), and will approach a 50:50 mix. As the sibling comment says, it's still used in cases where there's little to no chance of pregnancy, because we don't know another way to make it safe. |
