Precautions & Cautions
Be aware that this drug can cause low blood sugar (hypoglycemia), which may lead to seizures, loss of consciousness, permanent brain damage, and even death if not treated promptly. Discuss this risk with your doctor to understand how to manage it.
Additionally, this medication can cause low blood potassium (hypokalemia), which, if left untreated, may result in abnormal heart rhythms, severe breathing difficulties, and potentially death. Consult your doctor if you have concerns about this risk.
Until you understand how this medication affects you, avoid driving and other activities that require your full attention. Certain diabetes medications, such as pioglitazone or rosiglitazone, may increase the risk of heart failure, especially when used with insulin. If you are taking one of these medications, discuss this risk with your doctor.
Ensure you have the correct insulin product and understand how to measure and prepare your dose, as insulin products come in various containers, including vials, cartridges, and pens. If you have any questions, contact your doctor or pharmacist.
Be aware that stress, such as fever, infection, injury, or surgery, can make it more challenging to control your blood sugar levels. Changes in physical activity, exercise, or diet can also impact your blood sugar control.
Wear a medical alert identification to ensure prompt care in case of an emergency. Monitor your blood sugar levels as directed by your doctor and undergo blood tests as scheduled to ensure your treatment plan is working effectively.
Do not drive if you have experienced low blood sugar, as this can increase your risk of being involved in an accident. Consult your doctor before consuming alcohol or using products containing alcohol.
Adhere to the diet and exercise plan recommended by your doctor to maintain optimal blood sugar control. Never share your insulin product, including pens, cartridge devices, needles, or syringes, with another person, even if the needle has been changed, as this can transmit infections.
If you are 65 or older, use this medication with caution, as you may be more susceptible to side effects. Inform your doctor if you are pregnant, plan to become pregnant, or are breastfeeding, as you will need to discuss the potential benefits and risks to you and your baby.
Overdose Information
Overdose Symptoms:
- Severe hypoglycemia (very low blood sugar)
- Confusion
- Seizures
- Loss of consciousness
- Hypokalemia (low potassium levels)
What to Do:
Immediately consume fast-acting carbohydrates (e.g., glucose tablets, juice, candy). For severe hypoglycemia, glucagon injection may be needed. Seek immediate medical attention. Call 1-800-222-1222 (Poison Control).

- Alcohol (can potentiate hypoglycemic effect)
- Certain atypical antipsychotics (e.g., clozapine, olanzapine) (may cause hyperglycemia)
Moderate Interactions
- Oral antidiabetic agents (sulfonylureas, metformin, GLP-1 agonists, SGLT2 inhibitors, DPP-4 inhibitors) (increased risk of hypoglycemia)
- Corticosteroids (may increase blood glucose, requiring higher insulin doses)
- Diuretics (thiazide and loop diuretics) (may cause hyperglycemia)
- Sympathomimetics (e.g., decongestants, bronchodilators) (may increase blood glucose)
- Niacin (may increase blood glucose)
- Protease inhibitors (may affect glucose metabolism)
- Salicylates (e.g., aspirin in high doses) (may enhance hypoglycemic effect)
- ACE inhibitors (may enhance hypoglycemic effect)
- Somatostatin analogs (e.g., octreotide) (may affect insulin secretion and glucose levels)
Minor Interactions
- Certain antidepressants (MAOIs, SSRIs) (may affect glucose metabolism)
- Thyroid hormones (may affect glucose metabolism)
Monitoring
Baseline Monitoring
Rationale: To establish baseline glycemic control and guide initial dosing.
Timing: Prior to initiation of therapy.
Rationale: To establish baseline glucose levels.
Timing: Prior to initiation of therapy.
Rationale: To assess kidney function, as insulin clearance is partly renal and dose adjustments may be needed.
Timing: Prior to initiation and periodically thereafter.
Rationale: To assess liver function, as insulin metabolism occurs in the liver and dose adjustments may be needed.
Timing: Prior to initiation and periodically thereafter.
Routine Monitoring
Frequency: Multiple times daily (e.g., pre-meal, post-meal, bedtime, overnight) as directed by healthcare provider.
Target: Individualized (e.g., 80-130 mg/dL pre-meal, <180 mg/dL 2 hours post-meal)
Action Threshold: Hypoglycemia (<70 mg/dL), Hyperglycemia (>180-250 mg/dL depending on target)
Frequency: Every 3-6 months (or more frequently if glycemic control is suboptimal)
Target: Individualized (e.g., <7% for most adults)
Action Threshold: Above target range indicates need for dose adjustment or therapy change.
Frequency: Daily, ongoing
Target: N/A
Action Threshold: Presence of symptoms requires immediate action (e.g., glucose intake for hypoglycemia, insulin adjustment for hyperglycemia).
Frequency: Daily
Target: N/A
Action Threshold: Presence of lipodystrophy, redness, swelling, or pain requires site rotation or medical evaluation.
Symptom Monitoring
- Hypoglycemia: sweating, shakiness, dizziness, confusion, hunger, irritability, headache, blurred vision, rapid heartbeat, anxiety, weakness, slurred speech, seizures, unconsciousness.
- Hyperglycemia: increased thirst, increased urination, fatigue, blurred vision, headache, nausea, vomiting, fruity breath odor (ketoacidosis).
Special Patient Groups
Pregnancy
Insulin is the preferred treatment for diabetes in pregnancy (pre-existing or gestational diabetes) due to its efficacy and safety profile. It does not cross the placenta in significant amounts. Close monitoring of blood glucose is essential.
Trimester-Specific Risks:
Lactation
Insulin is compatible with breastfeeding. It is a large protein molecule and is not excreted into breast milk in clinically significant amounts. Insulin requirements may change during lactation.
Pediatric Use
Dosing must be highly individualized and adjusted frequently based on growth, pubertal status, activity levels, and carbohydrate intake. Close monitoring for hypoglycemia is crucial, especially in younger children who may not recognize symptoms. Education of parents/caregivers is vital.
Geriatric Use
Older adults may be more susceptible to hypoglycemia due to impaired renal/hepatic function, polypharmacy, and reduced counter-regulatory responses. Dosing should be conservative, and glycemic targets may be less stringent to avoid hypoglycemia. Close monitoring of blood glucose and renal function is important.
Clinical Information
Clinical Pearls
- Humulin 70/30 is a fixed-ratio combination; it cannot be adjusted for its individual components. If a patient needs more rapid-acting or more intermediate-acting insulin, a different regimen (e.g., basal-bolus) may be more appropriate.
- Always inspect the vial for clarity (Regular insulin should be clear, NPH should be cloudy). Humulin 70/30 should be uniformly cloudy after gentle mixing.
- Gently roll the vial between palms 10 times and invert 10 times immediately before drawing up the dose to ensure uniform suspension of NPH.
- Administer 30-45 minutes before a meal to allow the Regular insulin component to start working.
- Educate patients on proper injection technique, site rotation, and safe disposal of needles/syringes.
- Stress the importance of consistent meal times and carbohydrate intake to match the insulin's action profile.
- Patients should always have a source of fast-acting sugar readily available to treat hypoglycemia.
Alternative Therapies
- Basal insulins (e.g., insulin glargine, insulin detemir, insulin degludec)
- Bolus/prandial insulins (e.g., insulin aspart, insulin lispro, insulin glulisine, insulin regular)
- Oral antidiabetic agents (e.g., metformin, sulfonylureas, DPP-4 inhibitors, SGLT2 inhibitors, GLP-1 receptor agonists)
- Non-insulin injectable agents (e.g., GLP-1 receptor agonists, amylin analogs)
