Zoloft - Dyes and propylene glycol as ingredients - effects?

I was about to begin taking brand zoloft, but see that the ingredients contain propylene glycol, aluminum lake, the red dyes, etc. There does not seem to be a generic that is free of the aforementioned either.

I hypothesize that many people who have ill effects from taking sertraline are reacting to the other ingredients. Would you say that the risk-benefit ratio is worth making the attempt, assuming, that is, that I can convince myself that ingesting these unnecessary ingredients will do less harm than not taking the sertraline? (I'm tending towards a "Yes" on this, for now - but in a few weeks? Thank you.
