I found some 20 mcg caverject packs. Do you think that after the reconstitution , if I inject a quarter of it, can I keep the rest in refrigerator and use it the next days ?
I have never used Caverject, but I remember some other chemical PE practitioners in the old days (“first wave of chemical PE”) doing just that.
Decay within a matter of a few days (let’s say up to 3) should be minimal.
A short research didn’t yield any decay curves for stabilized PGE-1 in aqueous solution.
I have however found the official guide of Caverject, which is worth the read:
After reconstitution, the solution of CAVERJECT should be used within 24 hours when stored at or below 25°C (77°F) and not refrigerated or frozen. Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration whenever the solution and container permit.
