Treating multiple myeloma: how it is given and how long it lasts

Treatment for multiple myeloma is usually long-term rather than a fixed course. Most people start with a combination of medicines, which may include tablets, injections under the skin and drips, often alongside a steroid. This first treatment is given in repeating cycles over several months, mostly as an outpatient. People who are fit enough may then have high-intensity chemotherapy followed by a stem cell transplant using their own cells. After this, or instead of it, many people continue with gentler ongoing treatment, often tablets taken at home, for as long as it keeps the myeloma under control and is tolerated. Modern myeloma care relies on targeted and immune medicines as much as on traditional chemotherapy.

Because myeloma is usually managed as a long-term condition, treatment often continues for years, with changes along the way. If the myeloma becomes active again after a period of good control, a different combination is usually started. Many people go through several lines of treatment over the years, with breaks or lighter treatment in between, depending on how they feel. Regular blood and urine tests that measure the abnormal protein made by myeloma cells show how well the disease is controlled, and scans check the bones. This pattern differs from many other cancers, where chemotherapy is given for a set number of cycles and then stops, so patients and families may need to adjust their expectations and plans.

Typical effects depend on the medicines used. Tiredness, low blood counts, a higher risk of infection, numbness or tingling in the hands and feet, bowel changes, blood clots and steroid effects such as poor sleep, mood changes and higher blood sugar are common. Bone pain, kidney problems and high calcium can come from the myeloma itself rather than from treatment, so all new symptoms are worth reporting. A haematologist or medical oncologist leads care, often with kidney, bone and pain specialists. This page explains the general pattern and cannot describe your own plan. Your team will explain which medicines you will have, how they are given and how long treatment is expected to continue.

Long-term, not a fixed course

Treatment often continues or changes over years.

Tablets, injections and drips

Most treatment is given as an outpatient or at home.

Transplant for some

Fit people may have a stem cell transplant using their own cells.

It cannot tell you which medicines you will have or how long treatment will last. That depends on your myeloma, your health and how it responds.

It also cannot predict how well treatment will control your myeloma. Your haematologist can discuss your results.

Why myeloma is managed long-term

For most people, myeloma is controlled rather than removed for good. Treatment aims to bring the abnormal protein down, protect bones and kidneys, and keep symptoms away for as long as possible. Thinking of it as a long-term condition, with periods of treatment and periods of monitoring, helps families plan.

The stem cell transplant

An autologous transplant uses your own stem cells, collected from the blood after first treatment. High-intensity chemotherapy is given, then the cells are returned to help the marrow recover. It involves a hospital stay of a few weeks and is not suitable for everyone, particularly older or less fit people.

Protecting the bones

Myeloma can weaken bones and cause pain or fractures. Bone-strengthening medicines given by drip or injection are often part of care, and a dental check before starting them is usually advised. Radiotherapy or surgery may help painful or fragile areas of bone, as your team recommends.

Looking after the kidneys

The abnormal protein and high calcium can damage the kidneys. Drinking enough fluid, avoiding certain painkillers unless your team approves them, and having regular kidney tests all matter. Tell your team about any other medicines or supplements you take, so they can check that they are safe for your kidneys.

Infection risk

People with myeloma are more prone to infections, even between treatments. Vaccinations recommended by your team, preventive medicines where advised, good hygiene and prompt attention to any fever all help. Some people are given antibody infusions if infections keep coming back, as their haematologist decides.

Nerve damage

Some myeloma medicines can cause numbness, tingling or burning in the hands and feet. Myeloma itself can also affect nerves. Reporting symptoms early allows your team to adjust treatment before damage becomes lasting. Never change or skip medicines on your own; always discuss nerve symptoms at your next visit or sooner.

Blood clots

Certain medicines used in myeloma raise the risk of clots in the legs or lungs. Your team may recommend a blood thinner and will explain which symptoms to watch for. Staying active and drinking enough fluid help, and a painful swollen leg or sudden breathlessness needs urgent attention.

Tests that track myeloma

Blood and urine tests measure the abnormal protein, or parts of it called light chains. Changes in these levels show how well treatment is working and may give early warning that myeloma is becoming active again. Marrow tests and scans are repeated at key points to give a fuller picture.

When myeloma becomes active again

Myeloma often becomes active again after a period of control. This is expected and does not mean treatment failed. There are usually several further options, including different combinations, newer medicines, a second transplant for some people, or clinical trials. Your team will explain the choices at that point.

Older people with myeloma

Myeloma mostly affects older adults. Treatment can be adjusted for age, other illnesses and fitness, often using gentler combinations without a transplant. Good control is still possible. A frank conversation about what matters most, such as independence, comfort and time with family, helps shape a sensible plan.

The cost of long-term treatment

Because treatment continues for a long time, costs build up month after month. Asking about generic versions, insurance renewals, government schemes and financial counselling early helps families avoid gaps in treatment. Tell your team if cost is becoming difficult, so options can be discussed openly.

Living with ongoing treatment

Many people with myeloma work, travel and spend time with family while on treatment. Fatigue, pain and repeated hospital visits can still be wearing. Pacing activity, keeping a medicine diary, and support from counsellors or other people living with myeloma can make long-term treatment easier to manage.

What to do next

Ask your team which medicines you will start with, whether a transplant is being considered, how bones and kidneys will be protected, how often tests will be done, and what to do if a fever or new pain develops.
