Questions:
- If I pierce a 30 ml vial of bacteriostatic water once, draw 1.5 ml, and then leave the vial untouched at room temperature for several weeks or months – is the remaining water still safe to use later? Or does the 28‑day clock start after the first puncture regardless of how much I take?
- Does bacteriostatic water "die" or become unsafe simply because it was punctured once and then left alone, or is the 28‑day rule mainly about repeated punctures and contamination risk?
- For reconstituted teriparatide stored in a refrigerator – is 28 days a hard limit after which it definitely degrades, or can it remain effective for 60–90 days if the solution stays clear and aseptic technique is used?
- In practical home use with a single patient – what is the real safe storage period for an opened vial of bacteriostatic water and for reconstituted teriparatide?
