Short answer: Keep the Ovidrel prefilled syringe in the fridge at 36-46°F (2-8°C) so it lasts until the expiry date. You may instead keep it at room temperature, up to 77°F (25°C), for no more than 30 days, and it must be used within those 30 days. Store it in the original package. It is a single injection; discard any unused material. Source: Ovidrel label, Storage.
Storage: “Patients should store the pre-filled syringe refrigerated to allow the product to be used until the expiry date shown on the syringe or carton. The Ovidrel PreFilled Syringe may be stored by the patient for no more than 30 days at room temperature (up to 25°C (77°F)) but must be used within those 30 days.”
| Option | Temperature | Limit |
|---|---|---|
| Refrigerated | 36-46°F (2-8°C) | Until the expiry date on the syringe or carton |
| Room temperature | Up to 77°F (25°C) | No more than 30 days; must be used within them |
Also: “Store in original package. Discard unused material.” Ovidrel is recombinant hCG (choriogonadotropin alfa), already liquid, so there is no mixing.
No. Ovidrel is intended for a single injection under the skin, delivering 250 micrograms; any unused material is discarded. This differs from Novarel and Pregnyl, which are mixed and drawn from several times. More on the hCG page.
The room-temperature option stops at 77°F (25°C), lower than many GLP-1 pens. The label gives no allowance above that and no instruction for freezing. Ask your pharmacist or clinic before using a syringe that went outside these limits; trigger-shot timing is usually tight, so ask early.
Ovidrel can travel at room temperature up to 77°F (25°C) for up to 30 days, which counts toward its limit. In warm weather an insulated bag helps keep it under 77°F.
