Humalog

Warnings

Humalog is a fast-acting insulin that begins to work very quickly. If you use this medication with meal, use it within 15 minutes before or just after you eat.

Never share an injection pen, cartridge, or syringe with another person, even if the needle has been changed.

You should not use Humalog if you are having an episode of hypoglycemia (low blood sugar).

Humalog is only part of a complete program of treatment that may also include diet, exercise, weight control, foot care, eye care, dental care, and testing your blood sugar. Follow your diet, medication, and exercise routines very closely. Changing any of these factors can affect your blood sugar levels.
