At a glance
Infusion therapy in rheumatology is a treatment in which medication is delivered directly into a vein so it can reach the bloodstream quickly and in precise amounts. It is used when oral tablets either cannot deliver the drug effectively or are not strong enough to control a patient's condition.
The drug travels through a thin plastic tube called a cannula, inserted into a vein, usually in the arm. Once in the bloodstream, the medication works on the immune system, slowing or blocking the signals that cause joints, connective tissue (the fibres that hold the body together), or organs to become inflamed (swollen and damaged). Sessions typically last from thirty minutes to several hours, depending on which drug is used and how the body tolerates it.
Medical Condition
Rheumatologists prescribe infusion therapy when a disease involves the immune system attacking the body's own tissues and oral or injected treatments have not brought it under control. The conditions below are among the most common reasons a patient is referred for infusions.
- Rheumatoid arthritis (an autoimmune disease where the immune system attacks the joint lining, causing pain and swelling)
- Ankylosing spondylitis (chronic inflammation of the spine and large joints)
- Psoriatic arthritis (joint inflammation linked to the skin condition psoriasis)
- Systemic lupus erythematosus, often called lupus (an autoimmune disease that can affect the joints, skin, kidneys, and other organs)
- Vasculitis (inflammation of blood vessel walls)
- Myositis (inflammation of the muscles)
- Juvenile idiopathic arthritis (a form of arthritis that begins in childhood)
- Osteoporosis (thinning and weakening of the bones) when oral bone-strengthening drugs are not suitable
Infusion therapy may not be suitable for everyone. Doctors usually assess carefully before prescribing it in the situations below.
- Active serious infection such as tuberculosis, hepatitis B, or severe bacterial infection
- Severe heart failure that could be worsened by certain biologic drugs
- Known severe allergy to the specific drug or its ingredients
- Pregnancy or breastfeeding, depending on the drug chosen
- Significantly weakened immune system from another cause
Risks & Complications
Rheumatology infusion therapy is generally well tolerated, but like any treatment that affects the immune system, it carries risks that your medical team will monitor for during and after each session.
- Infusion reaction: flushing, rash, itching, or chills during the drip, which nurses can manage by slowing the infusion or giving antihistamines
- Increased risk of infection, because the drugs dampen immune activity
- Delayed allergic reaction occurring hours after the session ends
- Headache or mild fever after the infusion
- Nausea or fatigue lasting a day or two
- Bruising or soreness at the cannula site
- Rare but serious: severe allergic reaction (anaphylaxis) requiring immediate medical treatment
- Long-term use of some drugs carries a small risk of effects on the liver, kidneys, or blood cell counts, monitored through regular blood tests
Preparation & Procedure
Most rheumatology infusions do not require fasting, but your care team will give specific instructions based on the drug being used. Alcohol is best avoided in the day before a session, and smoking can affect circulation, so clinics often advise stopping on the day of treatment. If you take blood thinners or certain other medications, the prescribing doctor will decide whether to pause them beforehand.
Before the first infusion, and sometimes before later ones, a set of screening tests is usually ordered. These help confirm it is safe to proceed.
- Blood tests to check full blood count, liver function, and kidney function
- Screening for tuberculosis, hepatitis B, and hepatitis C, because the drugs can reactivate dormant (sleeping) infections
- A chest X-ray in some cases
- Pregnancy test if relevant
- Review of all current medications to check for interactions
On the day of the infusion, the steps below describe what typically happens, though the exact sequence can vary by hospital and by drug.
- 1. You arrive at the infusion suite or day clinic and are checked in by a nurse, who records your vital signs (blood pressure, pulse, temperature).
- 2. A nurse inserts a cannula into a vein in your arm or hand.
- 3. Pre-medications such as antihistamines or a low dose of a steroid are given through the cannula in some protocols to reduce the chance of a reaction.
- 4. The infusion bag containing your medication is connected and the drip begins at a slow rate.
- 5. The nurse gradually increases the drip speed if you are tolerating it well.
- 6. Throughout the session, your blood pressure, pulse, and any symptoms are checked at regular intervals.
- 7. Once the full dose has been delivered, the cannula is removed and you rest for a short observation period before being discharged.
Aftercare
Most patients go home the same day and can return to light daily activities, though fatigue or a mild headache in the hours after the infusion is common. Your team will explain which symptoms are expected and which ones warrant a phone call or a visit to the clinic.
- Stay in the clinic or infusion suite for the observation period your team specifies, usually at least thirty minutes after the drip finishes
- Keep the cannula site clean and dry; mild bruising at the site normally fades within a few days
- Drink plenty of water to help your body process the medication
- Avoid crowded places and people with obvious infections for a day or two, as the drug continues to affect immune responses after the session
- Report fever, chills, difficulty breathing, rash, or unusual pain to your medical team promptly
- Attend all scheduled follow-up appointments; blood tests are usually repeated at intervals to monitor for any effects on the liver, kidneys, or blood cells
- Infusion therapy is given in cycles, so your doctor will plan the full schedule of sessions in advance, typically every few weeks or months depending on the drug
- Lifestyle habits such as gentle exercise, a balanced diet, and not smoking support the treatment's effect on inflammation
Cost & What Determines It
The price of rheumatology infusion therapy can differ dramatically from one patient to the next, because so many factors specific to this treatment affect the final bill. The drug itself is often the single largest cost driver, and different drugs for the same condition can vary widely in price.
- Which drug is prescribed: biologic medications (drugs made from living cells) used in rheumatology are among the most expensive in medicine, and the choice of drug is determined by your diagnosis and disease severity
- Frequency and number of sessions: some conditions require infusions every few weeks for months or years, multiplying the total cost
- Hospital class: a private specialist hospital charges differently from a public academic centre, and costs differ substantially between countries
- Infusion suite facilities: dedicated infusion centres with private rooms cost more than shared day-ward settings
- Pre-infusion screening tests: blood panels, TB tests, and imaging ordered before starting therapy add to the upfront cost
- Pre-medications and supportive drugs given during the session
- Monitoring blood tests ordered at follow-up appointments between infusions
- Specialist consultation fees before and during the treatment course
Hospital packages for infusion therapy often bundle the nursing care, the infusion suite time, and the cannula and tubing into one fee. The drug itself, pre-infusion screening tests, specialist consultation fees, and follow-up blood tests are frequently billed separately, so patients should request a fully itemised estimate before committing.
For Indonesian patients, BPJS Kesehatan and most Indonesian private insurance policies do not cover treatment received abroad, meaning the full cost is usually paid out of pocket. Patients with international private insurance should verify coverage and pre-authorisation requirements directly with their insurer before travelling. Asking the hospital abroad for a written cost estimate that lists every expected charge is the most reliable way to plan your budget and avoid unexpected bills on arrival.
Frequently Asked Questions
How many sessions of infusion therapy will I need?
The number of sessions depends on your condition and how your body responds to treatment. Some people receive infusions every few weeks, while others have them monthly or even less often. Your rheumatologist will set a schedule after reviewing your diagnosis and how well the medication is working.
What does infusion therapy feel like during the session?
Most people feel little more than a small pinch when the needle is placed into a vein in the arm. Once the drip starts, you will usually sit or recline in a chair for anywhere from one to several hours while the medication enters your bloodstream slowly. Some patients feel mild fatigue or a slight chill during the session, but many find it quite tolerable.
How soon will I notice improvement after starting infusion therapy?
Many patients begin to notice less joint pain and stiffness after two or three sessions, though some people take longer to respond. Because the medication builds up in your system gradually, your doctor will usually ask you to complete several infusions before deciding whether the treatment is working. Patience is key, as early sessions are often about building a steady level of medication in your body.
How much does infusion therapy cost?
The cost varies depending on which medication is used, how long each session runs, how frequently you need treatment, and the class of hospital or clinic providing the service. Biologic medications (lab-made proteins that target specific parts of the immune system) used in rheumatology infusions can be a major cost factor on their own. Requesting a written estimate from your chosen hospital is the most reliable way to understand the full price for your specific treatment plan.
