How to inject insulin
Before injecting insulin, be sure to check its quality. If it was refrigerated, allow your insulin to come to room temperature. If the insulin is cloudy, mix the contents by rolling the vial between your hands for a few seconds. Be careful not to shake the vial. Short-acting insulin that isn’t mixed with other insulin shouldn’t be cloudy. Don’t use insulin that is grainy, thickened, or discolored.
