People also ask

What is Humulin S?

The Humulin S insulin medication contains human insulin as the active ingredient, which is used for the treatment of patients with diabetes mellitus who require insulin to maintain glucose homoeostasis. Humulin S is a rapid-acting insulin injection and is also indicated for the initial control of diabetes mellitus and in diabetes mellitus in pregnancy.

How does it work?

To counteract insulin resistance, The hypoglycaemic effect of insulin occurs when it binds to insulin receptors in muscle and fat cells, facilitating the absorption of glucose and simultaneously inhibiting hepatic glucose production. It is fast-acting insulin. The action starts after 30 min, the max effect. It occurs at 1.5 to 3.5 hours with an approximate duration of action of 7-8 hours.

What are the benefits of taking it?

Known for being a diabetes treatment medication; Humulin S helps the body convert blood sugar into energy. We always have a little sugar in our blood. This means that the pancreas has to produce small amounts of insulin during the day. When you eat, your blood sugar increases. This means that the pancreas needs to make more insulin during meals. When it is more active, the body uses more sugar and needs less insulin. When a person has diabetes, blood sugar remains high. That’s where Humulin S comes in and acts.

How do I use it and its dosage?

Make sure you get the Humulin S that your doctor has told you to use.

Follow exactly the instructions for the administration of Humulin S indicated by your doctor. Consult your doctor if you have doubts.


  • Your doctor has told you which insulin to use, how much, when, and how often to inject. These instructions are for you only. Follow them exactly and visit your diabetes clinic regularly. If you change the type of insulin (for example from animal to human), you may have to use more or less than before. This may only be on the first injection or it may be a gradual change over several weeks or months. Inject Humulin S under the skin. You should only inject it into a muscle if your doctor has told you to.

Preparing Humulin S

  • Humulin S is already dissolved in water, so there is no need to mix it. But you should only use it if it looks like water. It must be transparent and colorless and without solid particles. Check it every time you inject.

Injecting Humulin S

  1. First, wash your hands.
  2. Before injecting, thoroughly clean the skin as directed. Clean the rubber stopper of the vial, but do not remove it
  3. Use a new, sterile syringe and needle to puncture the rubber stopper and load the amount of Humulin S you need. Your doctor or diabetes educator will tell you how. Do not share your needles or syringes.
  4. Inject yourself under the skin, as you have been taught. Do not inject directly into a vein. After the injection, keep the needle injected into the skin for 5 seconds to be sure that the entire dose has been administered. Do not rub the area where you just injected. Make sure you are injecting at least 1 centimeter away from where you last injected and that you "alternate" the injection zones as you have been taught.
  5. Your doctor will tell you if you have to mix Humulin S with NPH Humulin. If, for example, you need to inject a mixture, load the syringe with Humulin S before doing so with the long-acting insulin. Inject the liquid as soon as you have mixed it. Repeat the same every time you need to inject a You should not normally mix Humulin S with a mixture of human insulins. You should never mix Humulin S with insulins produced by other manufacturers or with animal insulins.
  6. Humulin S should not be injected into a vein. Inject Humulin S as your doctor or diabetes educator has taught you. Only your doctor can inject Humulin S into your vein. You will only do this under special circumstances such as surgery or if you are sick and your glucose levels are too high.

Side effects & precautions

Like all medicines, Humulin S can cause side effects, although not everybody gets them.


Human insulin can cause hypoglycaemia (low blood sugar). Possible side effects include the following:

Systemic allergy: it is very rare (affects less than 1 in 10,000 patients treated). The symptoms are as follows:

  • Decreased blood pressure
  • Rash all over the body
  • Difficulty breathing
  • Wheezing (wheezing when breathing)
  • Fast heartbeat
  • Sweating

If you think you have this type of insulin allergy, tell your doctor immediately.

Local allergy: it is frequent (affects less than 1 in 10 treated patients). In some patients, the injection site becomes red, swollen, or itchy. Generally, these symptoms disappear in a few days or in a few weeks. If this happens to you, see your doctor.

  • Lipodystrophy (the skin becomes thicker or a kind of hole is formed): it is rare (it affects less than 1 in 100 treated patients). If you notice that your skin is getting thicker or a kind of hole in the places where you give the injections, tell your
  • Edema (e.g. swelling of the arms, ankles, fluid retention) has been reported, especially at the start of insulin treatment or during a change in treatment to improve the control of your blood

If you consider any of the adverse effects you suffer to be serious inform your doctor or pharmacist.


  • Hypoglycaemia (low blood sugar) means that there is not enough sugar in the blood. This can happen if:
  • Use too much Humulin S or other insulin
  • Skipping or delaying meals or changing your diet
  • Exercise or work too hard just before or after a meal
  • You have an infection or illness (especially diarrhoea or vomiting)
  • You have a change in your need for insulin
  • You have liver or kidney problems that get worse
