What is Humulin R

Humulin R is a lab strain of E. coli, which has been synthesized in order to control and help with insulin production in human beings.

How does Humulin R work?

Humulin R is used to treat the condition diabetes. People with diabetes have either a pancreas that cannot produce enough insulin to fulfill the body's requirements, or their body doesn't utilize the insulin the way it was designed to. Because of this, glucose cannot be used or stored properly in the body, resulting in the accumulation of glucose in the blood stream. Humulin R is a type of insulin that is injected subcutaneously under the skin in order to help control or lower blood glucose levels.

When/How is Humulin R taken/used/applied?

Normally regular insulin's such as Humulin R are administered about 30 minutes before any meal. There are many different dosages for Humulin R, and different medical factors are considered when finding the correct dosage, such as: how much insulin your pancreas is secreting, body weight and height, and other life style factors. Humulin R is usually applied via syringe or needle, subcutaneously under the skin with a special insulin syringe. Keep Humulin R insulin in the refrigerator until it's time to use, and discard after the expiration date. Insulin becomes less resistant once it is out of date, and will not work or be of any use to your body.

Humulin R side effects

Most side effects don't happen very often or by all persons taking Humulin R, however; if you experience any side effects contact your doctor because certain side effects could result in more serious problems if not treated in a timely manner. When taking Humulin R keep an eye out for side effects that could indicate low blood sugar, such as: anxiety, blurred vision, difficulty concentrating, difficulty speaking, dizziness, drowsiness, and headache. If you are experiencing these side effects on a regular basis your Humulin R dosage may need to be changed to a lower dose or less frequent doses. Stop taking your Humulin R immediately and seek prompt medical attention if any of these side effects occur: rash and blisters all over the body, seizures, swelling of the face or throat, difficulty breathing, or unconsciousness.
