After seeing the post about Phenylephrine, what other drugs do you feel do little or nothing?

After reading some of the comments on the post about phenylephrine, a few other ineffective meds that should be removed from the market were mentioned. It made me curious, which other meds do you think are a waste of time/money & do other pharmacists agree?

I frequently see docusate, now I’m hearing guaifenesin as well. Please help us save money by not buying medicine that won’t treat our symptoms!
