questions to ask before immune

Overview

Immune therapy (also called immunotherapy) is a type of treatment that works with your body's immune system — the system that fights infection and disease. Some immune therapies boost the immune system to help it attack illnesses like certain infections or cancers. Others calm the immune system down to control autoimmune conditions (where the immune system attacks healthy tissue). This article explains the questions you can ask your healthcare team before starting immune therapy, so you understand what to expect.

Immune therapy is becoming more common. It is used to treat a wide range of conditions, including certain autoimmune diseases, chronic infections, and some cancers. Many people will receive immune therapy at some point.

Immune therapy can be used for children and adults. It depends on the condition being treated. Your doctor will decide if immune therapy is right for you based on your specific illness and health history.

Symptoms

Common symptoms

• Recurrent infections that are slow to clear
• Unexplained fatigue or low energy
• Fever that comes and goes
• Swollen lymph nodes
• Unexplained weight loss or poor appetite
• Pain or inflammation in joints or skin

Symptoms in children

• Frequent ear infections or pneumonia
• Poor growth or delayed development
• Recurrent deep abscesses
• Severe or unusual infections

Symptoms in older adults

• Aching muscles or joints
• Unexpected shingles or other viral reactivation
• Feeling confused or weaker than usual with an infection
• Frequent falls due to weakness

Causes

Main causes

• The exact cause depends on the condition — it may be an overactive immune system (autoimmune), an underactive immune system (immunodeficiency), or an abnormal immune reaction to an infection.
• Some infections, like HIV or Epstein-Barr virus, can weaken or alter the immune system.
• Genetic conditions can affect how the immune system works.
• In some cases, treatments like chemotherapy or organ transplantation suppress the immune system.

Risk factors

• Family history of immune disorders
• Previous or current cancer treatment
• Long-term use of medicines that suppress the immune system
• Chronic infections (e.g., HIV, hepatitis)
• Smoking or heavy alcohol use
• Poor nutrition

When to see a doctor

See a doctor urgently if:

• If you have any symptoms of a serious infection, such as a high fever, severe headache, difficulty breathing, or a sudden rash that does not fade under a glass, seek urgent medical care.

Book a routine appointment if:

• If you are about to start immune therapy, you should ask your healthcare team the following questions: What are the benefits and risks of this treatment? How is it given and how often? How will we know it is working? What side effects should I report right away? Are there any activities or medicines I should avoid during treatment? How will my immune function be monitored? And what support is available to help me cope with any side effects?

Diagnosis

Before starting immune therapy, your doctor will run tests to confirm the diagnosis of the condition being treated. This usually begins with a full medical history and physical exam, followed by blood tests.

Tests that may be done

• Blood tests to check levels of immune cells
• Imaging scans (X-ray, CT, or MRI) to see parts of the body affected
• Biopsy of affected tissue in some cases
• Tests for specific infections

What to expect at your appointment

You will meet with your specialist several times. They will explain the treatment plan, including how it will be given, how long it will last, and what to expect during each session. You will be asked to sign a consent form after you understand and agree to the treatment.

Treatment

Immune therapy is one option in a wider treatment plan. The aim is to help your immune system work more effectively, whether it needs to be boosted, calmed down, or supported. Your treatment plan is personalised to you.

Self-care at home

• Keep all appointments and let your team know about any changes in how you feel
• Maintain good hand hygiene to prevent infections
• Eat a balanced diet and stay hydrated
• Get enough rest and gentle physical activity as you feel able
• Keep a list of any new symptoms or side effects to share with your team

Medical treatments

Immune therapies include a range of approaches. Some are given as injections under the skin, into a vein, or as pills. They may be used alone or in combination with other treatments, such as antibiotics, antivirals, steroids, or supportive medicines. Your specialist will explain which type is right for you and what to expect. Do not take any over-the-counter medicines, supplements, or herbal products unless you check with your pharmacist or doctor first.

When is surgery considered?

Surgery is not usually part of immune therapy itself, but it may be used to treat the underlying condition (for example, to remove an infected or cancerous area). Your care team will tell you if surgery is needed.

Living with this condition

Life on immune therapy requires planning and self-care. Some people feel well between doses; others have peaks and troughs of energy. Talk to your team about what your daily schedule might look like. You may need to arrange time off work or help with household tasks.

Lifestyle tips

• Protect yourself from infections by washing hands often, staying up to date with vaccines (as advised by your doctor), and avoiding crowded spaces when your immune system is weak
• Create a daily routine that balances rest and activity
• Ask for help from family and friends
• Keep a symptom diary to track how you feel

Diet and exercise

Eat a varied diet with enough protein and calories to support your immune system. If your appetite is poor, try small, frequent meals. Gentle exercise, like walking or stretching, can help maintain strength and mood, but always ask your team what is safe for you.

Mental health and emotional wellbeing

Living with a condition that affects your immune system can be stressful and worrying. It is normal to feel anxious or low. Talk to your team about how you are feeling. They can refer you to counselling or support groups if that would help. If you ever have thoughts of harming yourself, call your local emergency number or a crisis line right away.

Prevention

Not all immune conditions can be prevented. But you can reduce your risk of infections and complications by following your treatment plan and keeping your immune system as healthy as possible.

Vaccines

Some vaccines are not recommended during immune therapy because they may be less effective or could cause harm. Always ask your doctor or pharmacist before getting any vaccination.

Screening programmes

Your doctor may recommend regular blood tests to monitor your immune function and adjust treatment if needed.

Complications

If left untreated

• If the underlying immune condition is left untreated, it may worsen and cause damage to organs or increase the risk of serious infections.
• An overactive immune system can cause ongoing pain and inflammation.
• An underactive immune system can lead to recurring, severe, or unusual infections.

Long-term outlook

Immune therapy can be very effective for many people. It may control a condition for years, or even lead to long-term remission in some cases. While side effects can happen, most can be managed with the help of your healthcare team. A hopeful outcome is possible.
