Tianeptine hardened. I assume because of exposure to air. Nootropics

I had a 5 gram tub of Tianeptine. I was dosing from it but eventually it hardened. I was able to dissolve the hardened tianeptine in tap water. Now that I have it in tap water how long will it stay good for?

I put it in a 8oz, no spill container and added more water to it but I assume it cannot be kept in that form indefinitely. Although I can shake it up anytime I want if it begins to settle.

Or is tianeptine in tap water a bad idea. The tap water was purified with a Brita water filter, if that matters. I also stuck it in the refrigerator.

Thank you for considering my question
