Indications
- Diabetes Mellitus
- Diabetes Mellitus
Dosing
Diabetes Mellitus - SC injection Inject at start of meal or within 20 minutes after starting a meal into abdomen, upper arm, or thigh; generally use with intermediate- or long-acting insulin; individualize dose based on metabolic needs and blood glucose monitoring.
Diabetes Mellitus - Insulin pump (CSII) Administer by continuous SC infusion using an insulin pump; change FIASP reservoir at least every 6 days or PumpCart at least every 4 days; do not mix with other insulins in the pump.
Diabetes Mellitus - IV infusion Administer only under medical supervision; dilute to 0.5-1 unit/mL in polypropylene infusion bags with 0.9% sodium chloride or 5% dextrose; stable at room temperature for 24 hours.
Diabetes Mellitus Inject subcutaneously within 15 minutes before a meal into the abdominal wall, thigh, upper arm, or buttocks; typically dosed twice daily, with each dose intended to cover 2 meals or a meal and a snack; individualize dosage based on metabolic needs, blood glucose monitoring results, and glycemic control goal.
Contraindications
- Episodes of hypoglycemia
- Known hypersensitivity to insulin aspart or any excipient in FIASP
- During episodes of hypoglycemia
- Known hypersensitivity to HUMALOG Mix50/50 or any of its excipients
Adverse Reactions
Most common (>=5%) Nasopharyngitis, upper respiratory tract infection, nausea, diarrhea, back pain (adults with T1D); urinary tract infection (adults with T2D); viral upper respiratory tract infection, upper respiratory tract infection, influenza, headache, pyrexia, vomiting (pediatric T1D)
Serious Hypoglycemia, hypokalemia, severe hypersensitivity reactions including anaphylaxis, angioedema, bronchospasm, hypotension, and shock; lipodystrophy; injection or infusion site reactions; peripheral edema; weight gain
Postmarketing Localized cutaneous amyloidosis at injection site; hyperglycemia with repeated injections into amyloidosis areas; hypoglycemia with sudden change to unaffected injection site
Most common Hypoglycemia
Serious Severe hypersensitivity reactions including anaphylaxis, hypokalemia
Postmarketing Ophthalmologic refraction disorder, worsening of diabetic retinopathy, acute painful peripheral neuropathy, injection site reactions (redness, swelling, itching), lipodystrophy, localized cutaneous amyloidosis, peripheral edema, weight gain, anti-insulin antibody formation
Pharmacology
Rapid-acting insulin analog; binds to insulin receptors to lower blood glucose by facilitating cellular uptake of glucose into skeletal muscle and adipose tissue and inhibiting hepatic glucose output, while also inhibiting lipolysis and proteolysis and enhancing protein synthesis.
Insulin lispro is a rapid-acting human insulin analog that regulates glucose metabolism by stimulating peripheral glucose uptake in skeletal muscle and fat and inhibiting hepatic glucose production; Humalog Mix50/50 combines 50% insulin lispro (rapid-acting) and 50% insulin lispro protamine suspension (intermediate-acting) to provide both rapid onset and prolonged glucose-lowering activity.
