One concern for midwives is the storage of ergonovine, carboprost and oxytocin for women planning homebirths. Storage and refrigeration is essential to the efficacy of ergometrine. Ergometrine loses 21-27% of active ingredients after 1 month and 90% after 1 year of storage exposed to light and at 21-25 degrees Celsius. For most effective long-term storage, ergonovine must be kept between 2-8 degrees Celsius and protected from light. Similarly, carboprost must also be stored at between 2-8 degrees Celsius.62 Oxytocin is ideally stored between 15-30C and should be protected from freezing.27 Midwives should not store these drugs in their cars where large temperature fluctuations can adversely affect their efficacy.
