What is Humulin® 70/30?

Insulin is a hormone produced by the pancreas to managed blood sugar levels. It works by decreasing sugar in our blood and urine by increasing the uptake of sugar from blood into the various tissues such as our muscles, liver and fat.

For those with diabetes, our body either does not produce enough insulin or not at all. This is why insulin injections are necessary in order to keep blood sugar levels within a normal range.

Humulin 30/70 is used to treat patients diagnosed with type 1 and type 2 diabetes mellitus.

Humulin 30/70 combines both intermediate-acting (Humulin N) and short-acting insulin (Humulin R U-100). It’s covers your insulin needs after meals, throughout the day and during bedtime.

This insulin is produced using recombinant DNA processes. Due to its unique manufacturing process, Humulin differs from animal-source insulin but structurally identical to that produced by the pancreas in our body.

Medication is administered through injection under the skin (subcutaneous) and duration can last between 16-18 hours.

HUMULIN 30/70 is a fixed mixture of:

  • 30% Humulin R Regular (insulin injection, human biosynthetic)
  • 70% Humulin N- NPH (insulin isophane, human biosynthetic)

Side Effects

However rare, the side effects associated to Humulin can occur as with any insulin medication.

The most common side effect is low blood sugar (hypoglycemia). Signs of hypoglycemia include:

  • unconsciousness
  • disorientation
  • seizures
  • death

Diabetic Acidosis (DKA)

Diabetic Acidosis (DKA) may develop if your body has too little insulin. This can result from insulin rationing, taking less than your doctor prescribed, eating more than your diet suggests or developing an infection or fever.

Symptoms of Diabetic Acidosis include:

  • flushed face
  • loss of appetite
  • thirst
  • drowsiness

More serious symptoms of DKA can include heavy breathing and increased heart rate.

Urine tests have shown that when diabetics experience acidosis, their urine contains a high amount of sugar and acetone.

If untreated, diabetic acidosis can lead to loss of consciousness, coma or can be fatal.

If you believe you are experiencing DKA, seek medical attention immediately.

Allergic Reactions

Insulin users may experience allergic reactions. This can be visible in the form of swelling, redness and itching at the site of injection called local allergy. This typically goes away after a few days. Let your doctor know if you experience any allergic reactions as they my prescribe a different type of insulin or dosage.

If you experience a rash all over your body this can potentially be serious. If you are showing these symptoms in addition to shortness of breath, wheezing, low blood pressure, sweating, increased pulse notify your doctor.

If you are experiencing a generalized allergic reaction, this can be severe and you should seek medical attention immediately.

Your doctor may recommend a skin allergy test to see how your body reacts to other insulin in order to choose the one that is best for you.

Skin reactions at the site of injection may occur. This can include localized cutaneous amyloidosis, lipoatrophy or lipohypertrophy.

If you notice any skin lumps on areas of injection, notify your doctor.
