How long before effects of insulin stop?

A doctor has provided 1 answer

Depending on type: Rapid, short-acting Insulin such as NovoLog starts working in15 mins and last 3-5 hours, Humalog starts in about 30 mins =, lasting 2-4 hours. Insulin-nph starts in about 1-1.5 hours, may last up to 24hours (often to about 14 hrs). Levemir (insulin detemir) or Lantus starts in about 3-4 hours and lasts about 24 hours, as these are basal insulin. Consult your pharmacist/doc. Good luck.
