What is Infusion Therapy

Sometimes, when we think about how far science has progressed we are left to wonder just how many deaths could have been prevented if those who lived in times past had the knowledge that we do. For example, in the past, all medication, save for balms and salves, was oral medication. This meant that medication would have to pass through the digestive tract (which may sometimes reduce its efficacy) before being absorbed into the bloodstream. Sadly, in cases of emergency, the whole process of digestion and absorption may take just too long- a situation that no doubt led to the death of countless millions. Infusion therapy was, therefore, a welcome development as it did away with the need for oral introductory of medicine and is particularly efficient in emergency cases as it bypassed the alimentary canal and introduced medication or fluid directly into the bloodstream. This article addresses all you need to know about Infusion Therapy.

Infusion Therapy

Infusion Therapy is the administration of medication or drugs through the vein with the aid of a needle or catheter. Infusion therapy allows caregivers to administer certain medications that either can’t be taken orally or requires dispensation at a regulated speed. There are different types of infusion therapy, namely:

  1. Subcutaneous
  2. Intramuscular
  3. Epidural
  4. Insulin Pumps

It is noteworthy that while infusion therapy is mainly utilized to transmit medication, that is not its only purpose as it can also be used to administer nutrition. Some of these medications and nutrition include:

  1. Inotropic heart medication
  2. Immunoglobulin replacement
  3. Blood factors
  4. Corticosteroids
  5. Chemotherapy
  6. Antibiotics

What kind of condition is infusion therapy used for?

Apart from emergencies such as stroke, heart attack, poisoning, and anaphylactic shock where theirs is an urgent need for medication to get into the bloodstream, Infusion therapy is utilized in the treatment of cancer. In chemotherapy for cancer, certain medications cannot be ingested orally as there is a need to inject them directly into the spine or to a specific part of the body.

How does Infusion Therapy work?

Infusion therapy is usually carried out in a clinic or hospital by a doctor, nurse, or other qualified healthcare professional. To avoid the risk of infection, at each scheduled Infusion therapy a new needle stick is utilized. However, where you need several infusion therapy sessions, and to avoid scarring and needless pain from the jab of the needle, your doctor may either surgically implant a port under your skin or insert central lines into your chest, neck, or groin.

To begin the process of infusion therapy, typically, a nurse or doctor searches for a suitable vein, usually in your arm, and inserts a needle into it. Then, a tube is attached to the IV bag which is hung in such a way that gravity allows its content to flow into your bloodstream at apace regulated by the catheter.

Risks of Infusion Therapy

  1. Scarring from several needle insertions
  2. Collapsed veins
  3. Air embolism
  4. Infection


Infusion therapy is a lifesaving scientific marvel that ameliorates the delays of oral medication. And it is evident that its rewards are well worth its risk.
