Cymbalta not working

I am on cymbalta at 30 mg per day but my mood is still down. Can I take a herbal supplement?

When you are prescribed anti-depressants, it is recommended that you not take any other type of herbal supplement because of the risk of interactions. The dose of cymbalta you are taking is too small, I think you can safely go to 60-120 mg per day. Speak to your doctor before you increase the dose. I think a higher dose for adults works well.
