Hypoglycemia can occur very quickly and usually within 2 hours after injection. Recheck blood glucose after 15 minutes to see if more carb is needed. After treating hypoglycemia due to Regular insulin, a snack is often needed to prevent another drop in glucose. A follow-up snack may not necessarily be needed for people using Humalog because of its short duration of action. Taking Humalog at bedtime or during the night is risky when not followed by food.
Severe hypoglycemia is more likely.
If you must take Humalog before bedtime, it is highly advised to recheck blood glucose within 60-90 minutes to be sure that you do not drop too low during the night. All rights reserved.
