Is ZenCortex for short-term relief or long-term use?

Zencortex is sold as a dietary product to help keep your hearing healthy. From what it says, it sounds like it's meant to be used for a long time instead of just for a short time. The supplement is meant to be used every day as drops, and each bottle lasts for 30 days. This means that it should be taken constantly to improve hearing health over time.
