Intravenous (IV) therapy is a common procedure in hospitals, with over 90% of hospitalized patients receiving it as part of their care. IV therapy involves delivering fluids, blood, or medication directly into a patient's circulatory system through their veins. This method ensures rapid and effective distribution throughout the body, making it ideal for emergency situations or when a fast onset of action is required. IV therapy is particularly useful when oral intake is not possible or insufficient, such as in cases of severe gastrointestinal issues, eating disorders, or difficulty swallowing. It is also essential for administering chemotherapy drugs, blood transfusions, and potent antibiotic or antifungal therapies. Outside of medical settings, IV therapy has gained popularity as an on-demand service for hydration, vitamins, and other additives, despite limited evidence of its benefits in healthy individuals.

To deliver fluids, blood, or medication directly into a patient's system
Intravenous (IV) therapy is a common procedure, with over 90% of hospitalised patients receiving an IV as part of their care. IV therapy is the delivery of fluids, blood, or medication directly into a patient’s system through the veins. This makes IV therapy incredibly effective for patients who need rapid drug delivery or other IV fluids.
IV therapy is often used to deliver emergency drugs quickly and efficiently when they are needed. For example, in cases of extremely high blood pressure, IV antihypertensives may be administered to lower blood pressure in a controlled manner and prevent organ damage. Similarly, in atrial fibrillation, IV amiodarone may be used to restore a normal heart rhythm.
IV therapy is also used to deliver fluids to patients who are dehydrated or at risk of dehydration. This can occur when patients are required to fast before surgery or other diagnostic tests. A saline drip can help to keep patients hydrated when they are unable to drink. IV fluids can also help to maintain a patient's hydration, electrolyte, and blood sugar levels during surgery.
In some cases, IV therapy may be the only route for delivering medication or nutrition to a patient. This includes patients with a malfunctioning gastrointestinal tract or disorders requiring total bowel rest, such as short bowel syndrome or severe Crohn's disease. Patients with severe eating disorders or difficulty swallowing may also require parenteral nutrition through an IV. Certain medications, such as chemotherapy drugs, are also commonly administered intravenously.

To maintain hydration, electrolyte and blood sugar levels
Intravenous (IV) therapy is a common procedure in hospitals, with over 90% of hospitalised patients receiving an IV as part of their care. IV therapy is the delivery of fluids, blood, or medication directly into a patient's circulatory system through their veins. This makes it incredibly effective for patients who need rapid drug delivery or other IV fluids.
IV therapy is often used to maintain hydration, electrolyte, and blood sugar levels. When patients cannot eat or drink, they can become dehydrated, and even slight dehydration can cause odd symptoms that may interfere with test results. IV fluids can prevent this. For example, patients who are required to fast before surgery are often given a litre bag of normal saline or dextrose over eight hours to keep them hydrated while they wait.
IV therapy can also be used to deliver a "special blend of vitamins and electrolytes," as well as medications to treat symptoms such as nausea, pain, and heartburn. However, it is important to note that the benefits of IV fluids for those who are well-nourished and well-hydrated are unproven, and there are financial costs associated with this treatment.
IV therapy is generally safe and effective, but it can cause side effects, especially if the person administering it has not been fully trained. Therefore, it is recommended that IV therapy be performed in a medical setting by trained professionals.

To deliver emergency drugs quickly and efficiently
Intravenous (IV) therapy is a common procedure in hospitals, with over 90% of hospitalised patients receiving IV therapy as part of their care. It is the delivery of fluids, blood, or medication directly into a patient's circulatory system through their veins.
IV therapy is the fastest way to deliver medications and fluid replacement throughout the body. This makes it ideal for emergency situations or when a rapid onset of action is required. For example, in cases of extremely high blood pressure, IV antihypertensives can be administered to quickly and safely reduce blood pressure and prevent organ damage. Similarly, in atrial fibrillation, IV amiodarone can be used to restore a normal heart rhythm.
IV therapy is also used to deliver emergency drugs during surgery. It allows doctors to administer pain medications, antibiotics, and other vital fluids quickly and efficiently. It is also used to maintain a patient's hydration, electrolyte, and blood sugar levels during surgery. Additionally, IV therapy is useful when a patient's digestive system is not functioning properly, or when they are unable to meet their nutritional requirements through oral intake alone. This includes patients with severe eating disorders, difficulty swallowing, or disorders requiring total bowel rest, such as short bowel syndrome or severe Crohn's disease.
IV therapy can also be used to administer chemotherapy drugs for cancer treatment. In some cases, a loading or bolus dose of medicine is given intravenously before beginning a dosing regimen to quickly increase the concentration of medication in the blood. The bioavailability of IV medications is 100%, compared to oral administration where medication may be metabolised before entering the bloodstream.

To help patients who are unable to meet their nutritional requirements through oral intake alone
Intravenous (IV) therapy is a common procedure in hospitals, with over 90% of hospitalised patients receiving an IV as part of their care. IV therapy is the delivery of fluids, blood, or medication directly into a patient's circulatory system through their veins. This method of delivery is incredibly effective when rapid delivery of drugs or other IV fluids is required.
IV therapy can be life-saving for patients who are unable to meet their nutritional requirements through oral intake alone. This includes patients with a non-functioning gastrointestinal tract or disorders requiring total bowel rest, such as short bowel syndrome or severe Crohn's disease. Patients with severe eating disorders or dysphagia (difficulty swallowing) may also experience malnutrition due to their inability to consume adequate nutrition orally.
In such cases, parenteral nutrition, or Partial Parenteral Nutrition (PPN) and Total Parenteral Nutrition (TPN), can be life-saving. PPN and TPN are methods of feeding that supply some or all of a patient's daily nutritional requirements intravenously. This ensures that the patient receives the necessary nutrients directly into their bloodstream, bypassing the digestive system.
Additionally, IV therapy can be used to administer specific nutrients or vitamins that may be lacking in a patient's diet. For example, high doses of vitamin C may be administered intravenously to people living with cancer. However, it is important to note that there is currently insufficient evidence to recommend the use of multivitamin IV therapy outside of medical settings, and most daily vitamin requirements can be easily obtained through a well-balanced diet.
IV therapy is generally safe and effective, but it can cause side effects, especially if performed by untrained individuals or in uncontrolled settings. Therefore, it is recommended that IV therapy be administered by trained medical professionals in a hospital or clinical setting to ensure patient safety and proper monitoring.

To deliver chemotherapy drugs
Intravenous (IV) therapy is a common procedure in hospitals, with over 90% of hospitalised patients receiving an IV as part of their care. IV therapy is used to deliver fluids, blood, or medication directly into a patient's circulatory system, making it the fastest way to deliver medications and fluids.
IV therapy is often used to deliver chemotherapy drugs to cancer patients. Chemotherapy is a common cancer treatment that uses drugs to destroy cancer cells and prevent tumour growth. It is usually given intravenously, directly into a vein through a needle, catheter, port, or pump. A needle is usually inserted into the arm, although a catheter is often placed in the chest, where it is attached to a port under the skin.
IV chemotherapy is typically administered in a hospital setting, although some patients may receive it in an outpatient setting or at home. It is usually given once every few weeks, although the length of treatment depends on the type of chemotherapy and the patient's response to it. The bioavailability of IV medication is 100%, meaning that it is completely absorbed into the bloodstream, unlike oral medication, which may not be fully absorbed.
IV chemotherapy can be used in different ways depending on the patient's needs. It can be used as adjuvant therapy to destroy cancer cells after surgery or radiation therapy, or as curative therapy to eliminate the cancer completely. It can also be used as neoadjuvant therapy to shrink a tumour before surgery or radiation therapy, or as palliative therapy to shrink tumours and lessen symptoms without curing the cancer.
In addition to IV chemotherapy, there are other ways to deliver chemotherapy drugs. These include oral chemotherapy, which comes in pill or liquid gel form and can be taken at home, and intra-arterial (IA) chemotherapy, which is delivered directly into the main artery supplying blood to the tumour. The choice between IV and oral chemotherapy depends on various factors, including the patient's preference, the type of cancer, and insurance coverage.
