How long does a vial of reconstituted TIRZ last if kept refrigerated?

I am on my second week of 2.5mg of TIRZ. Had a little heartburn last week, but this week has been on another level. Acid reflux and general indigestion. I have a strong history of acid reflux but normally am able to manage it with daily 20mg Omeprozole. Unfortunately, for the last couple days, I've been taking Tums non-stop and a few doses of Pepto. To be fair, I did drink a glass of red wine and eat pasta with red sauce. I learned my lesson so now really being careful with acidic foods. Any similar issues or advice?
