You should not use Levemir if you are allergic to insulin detemir, or if you are in a state of diabetic ketoacidosis (call your doctor for treatment with a short-acting insulin).
Never share a Levemir injection pen or syringe with another person, even if the needle has been changed.
Many other drugs can potentially interfere with the effects of Levemir. It is extremely important that you tell your doctor about all the prescription and over-the-counter medications you use. This includes prescription, over-the-counter, vitamin, and herbal products. Do not start a new medication without telling your doctor.
Low blood sugar (hypoglycemia) can occur if you skip a meal, exercise too long, drink alcohol, or are under stress. An insulin overdose can cause life-threatening hypoglycemia. Know the signs of low blood sugar (hypoglycemia) and how to recognize them: headache, hunger, weakness, sweating, tremors, irritability, or trouble concentrating. Be sure your family and close friends know how to help you in an emergency.
