Lupus is an autoimmune disease. This means that the body's natural defence system (immune system) attacks healthy tissues instead of attacking only things like bacteria and viruses. This causes inflammation.
Although some people with lupus have only mild symptoms, the disease is lifelong and can become severe. But most people can control their symptoms and prevent severe damage to their organs. They do this by seeing their doctors often for checkups, getting enough rest and exercise, and taking medicines.
This topic focuses on systemic lupus erythematosus (SLE), the most common and most serious type of lupus. But there are other types of lupus, such as discoid or cutaneous lupus, drug-induced systemic lupus, and neonatal lupus.
The exact cause of lupus is not known. Experts believe that some people are born with certain genes that affect how the immune system works. These people are more likely to get lupus. Then a number of other things can trigger lupus attacks. These include viral infections, including the virus that causes mononucleosis, and sunlight.
Although these things can trigger lupus, they may affect one person but not another person.
Lupus symptoms vary widely, and they come and go. The times when symptoms get worse are called relapses, or flares. The times when symptoms are under control are called remissions.
Common symptoms include feeling very tired and having joint pain or swelling (arthritis), a fever, and a skin rash. The rash often happens after you have been in the sun. You may have mouth sores and hair loss. Over time, some people with lupus have problems with the heart, lungs, kidneys, blood cells, or nervous system.
There is no single test for lupus. Because lupus affects different people in different ways, it can be hard to diagnose.
Your doctor will check for lupus by examining you, asking you questions about your symptoms and past health, and doing some urine and blood tests.
Treatment for lupus may include:
The doctor may also recommend other medicines that slow down the immune system (immunosuppressants).
One of the goals of controlling mild to moderate lupus symptoms is to prevent flares. You can:
With good self-care, most people who have lupus can keep doing their regular daily activities.
It is important to learn about lupus so that you can understand how it might affect your life and how you can best cope with it. Also, help your family and friends understand your limitations and needs when your symptoms flare. Build a support system of family, friends, and health professionals.

The exact cause of lupus is not known. Experts believe that some people are born with certain genes that affect how the immune system works. These people are more likely to get lupus. Then a number of other things can trigger lupus attacks. These include certain medicines, certain chemicals, tobacco smoke, certain infections, and sunlight. Although these things can trigger lupus, they may affect one person but not another person.
Lupus symptoms depend on what body organs are affected and how seriously they are affected.
Many people have these symptoms:
Other conditions with symptoms similar to lupus include fibromyalgia and chronic fatigue syndrome.
The course of lupus varies by individual and is hard to predict, because symptoms come and go. Lupus usually develops so slowly that a person may not notice the symptoms for a long time. Sometimes lupus develops and progresses rapidly.
Periods of time when you have lupus symptoms are called flares or relapses. Periods of time when your symptoms are under control are called remissions. Flares and remissions can occur abruptly, unexpectedly, and without clear cause. There is no way to predict when a flare will happen, how bad it will be, or how long it will last. When you have a lupus flare, you may have new symptoms in addition to those you have had in the past.
Children can get lupus, though it more commonly develops in the teen years or later. Lupus in children appears to be more severe than in adults when vital organs, such as the kidneys and heart, are involved.
Some people with lupus have complications such as kidney and heart problems. There are also concerns if you have lupus and are pregnant.
Most people with lupus are able to continue their usual daily activities. But when your symptoms flare, you may find that you need to cut back on your activity level, get help with child care, or change the way you work. Or you may find that you need time off from all daily activities.
Most people with lupus can expect to live a normal or near-normal lifespan. This depends on how severe your disease is, whether it affects vital organs (such as the kidneys), and how severely these organs are affected.
A key to living with lupus is communication. Stay in touch with your doctor about new or increased symptoms, side effects of medicines, and your worries and anxieties. Talk with your family, friends, and employer so they understand what you can and can't do, and what they can do to support you.
The chances of developing lupus are higher in people who:
Certain things can trigger lupus attacks. These may include:
Hormones, including those used for hormone therapy or birth control, don't cause lupus. But they may have some effect on it.
Talk with your doctor about whether you should use hormonal birth control or hormone therapy.
or other emergency services immediately if you have symptoms of a heart attack. These may include:
After you call 911, the operator may tell you to chew 1 adult-strength or 2 to 4 low-dose aspirin. Wait for an ambulance. Do not try to drive yourself.
or other emergency services immediately if you have one or more of the following signs of a stroke:
Call a doctor immediately if you:
Call a doctor as soon as possible if you develop any new symptoms of lupus. Also call your doctor if any symptoms that you have had for a period of time get worse.
If you have not been diagnosed with lupus and you have symptoms such as joint pain, fatigue, or skin rashes, see your doctor or tell your doctor about your concerns at your next medical appointment.
Your family doctor or general practitioner can evaluate initial symptoms and treat mild lupus.
For long-term management of complicated lupus you may be referred to a specialist, such as:
For more complicated cases of lupus, a rheumatologist is usually the primary doctor. Other specialists are consulted as needed.
To prepare for your appointment, see the topic Making the Most of Your Appointment.
Lupus can be hard to recognize, and it sometimes takes weeks to years to diagnose. Lupus affects different people in different ways. And it can take time for symptoms to develop.
Your doctor will record your medical history and do a physical examination. He or she will check for certain criteria to help diagnose lupus. These criteria include the butterfly rash and joint swelling.
If you have symptoms of lupus and you have a positive antinuclear antibody (ANA) test result, further testing may not be needed.
If your doctor feels that further testing is needed, you may have one or more of the following tests:
As part of ongoing treatment for lupus, you may have a:
To look for other possible causes of symptoms, imaging tests are sometimes done, depending on which organ systems are involved. Imaging tests include CT scan, echocardiogram, MRI, and X-rays.
Your treatment choices for lupus depend on how severe your symptoms are, whether your organs are affected, and how much your symptoms are affecting your daily life. Your treatment plans should be tailored to your individual needs and will change over time, as the disease flares or ebbs. There currently is no cure for lupus.
The goal of treatment for mild lupus is to prevent symptom flares-when fatigue, joint pain, and rash get worse.
If your lupus is causing or threatening organ damage, is life-threatening, or is seriously impacting your quality of life, you may also need to take:
To learn more, see Medications.
If you develop serious kidney disease that cannot be controlled with medicine, you may need dialysis or a kidney transplant.
Good self-care is essential to managing lupus. A healthy lifestyle may reduce how often you have flares and how severe they are. It can improve your quality of life. Good self-care also helps decrease the risk of heart attack and stroke.
Self-care includes getting regular exercise and eating a healthy diet. To learn more, see Home Treatment.
Taking corticosteroids by mouth and being physically inactive put people with lupus at great risk of bone thinning (osteoporosis). Getting an adequate supply of calcium and vitamin D may slow the bone thinning process. Your doctor may also prescribe bisphosphonates, a type of medicine that is also used for the prevention and treatment of osteoporosis. To learn more, see the topic Osteoporosis.
Lupus treatment is complicated by several things. The course and pattern of lupus symptoms vary widely. Flares and remissions can occur at any time, making it hard to tell how you are responding to treatment or which treatments are most helpful. Some treatment side effects can be as troubling as the symptoms of lupus.
It may not be possible to completely eliminate all of your symptoms for long periods of time, especially without the side effects from medicines. Work closely with your doctor to reach a balance between reasonably controlling your symptoms, preventing damage to your organs, and minimizing side effects of long-term drug treatment. For example, you may take a dose of medicine that will control lupus enough to prevent organ damage, but you may still have symptoms such as mild skin rash, muscle aches, and joint pain.
Using higher doses of medicines for a long time increases the risk of serious side effects. Your doctor will prescribe a dose that controls only the most serious, life-threatening symptoms and balances the risks of the medicines with the benefits of controlling your symptoms.
There is currently no way to prevent lupus. But people who smoke may be more likely to get lupus. Avoiding smoking and perhaps other tobacco products may decrease your risk.
Good self-care is essential to managing lupus. Learn to recognize your body's warning signs of a flare. Warning signs may include increased fatigue, joint pain, rash, or fever. When you notice any of these signs, take steps to control your symptoms.
Stress may trigger lupus symptoms. Keep your stress level as low as you can.
Fatigue is common in people with lupus. To fight fatigue:
Take care of your skin. Ask your doctor about the use of corticosteroid creams to relieve skin symptoms that are particularly troublesome. If you are bothered by the way a lupus rash looks on your face or if you have scars from lupus, you can try makeup, such as Covermark, to cover the rash or scars.
(UVA and UVB) light triggers disease flares in most people who have lupus. Exposure to ultraviolet light, as from sunlight, can trigger or start skin rash, joint pain, or fatigue, or it can make these symptoms worse. To minimize your exposure to ultraviolet light:
Good general care is essential. A healthy lifestyle not only improves your quality of life but may also reduce your chances of having more frequent and severe flares. Taking good general care of yourself also helps decrease the risk of heart attack and stroke. Good care includes:
Other good health habits that will help protect you include:
If you have lupus and are a woman in your child-bearing years, pay special attention to pregnancy-related concerns, both before you conceive and while pregnant. Most women with well-controlled lupus can take birth control pills if they choose. And for most women, lupus won't interfere with becoming pregnant or with pregnancy. But some women with lupus, especially those with active disease, are at higher risk of problems from pregnancy. All women of child-bearing age should check with their rheumatologist when they are planning to become pregnant.
Home treatment and regular checkups are sometimes enough for managing mild lupus or for periods of remission. Be sure to have regular checkups. These checks are important to help find and treat progressive organ damage.
It is important that the people in your life understand what lupus is, how it affects your life, and how you can best cope with it. Help them understand your limitations and needs when your symptoms flare. Support groups are great places to learn coping strategies from others.
Medicines can't cure lupus, but they can control many symptoms and often can prevent or slow organ damage.
Medicine treatment for lupus often involves reaching a balance between preventing organ damage, having an acceptable quality of life, and minimizing side effects. You will need to see your doctor often to see how you're doing and check for medicine side effects.
Your doctor may have to change the dose and combinations of medicines until you reach the best possible balance.
If you have mild disease or symptoms that affect your quality of life but you don't have organ-threatening problems, your doctor may prescribe:
If you have more severe disease, your doctor may prescribe:
If you have had blood clots in a vein or artery (venous or arterial thrombosis), or have antiphospholipid antibody syndrome, which increases your risk for blood clots, your doctor may prescribe a blood thinner (anticoagulant). This is especially important if you already have blood clots. Aspirin is a non-steroidal anti-inflammatory drug (NSAID) that is sometimes used to slow blood clotting in antiphospholipid antibody syndrome.
Some lupus medicines, like acetaminophen and prednisone, are considered safe during pregnancy. Others may not be. You may not be able to stop taking lupus medicines after becoming pregnant. Or you may need to start taking medicines for a symptom flare. If possible, talk to your doctor before becoming pregnant so you can learn about the effect lupus may have on your pregnancy.
Because corticosteroids are powerful medicines and can cause serious side effects, your doctor will recommend the lowest dose that will give the most benefit.
Some people with lupus are sensitive to antibiotic medicines called sulfonamides (sulfa medicines). These include Septra and many others. Your doctor can prescribe medicines that don't contain sulfa, if needed.
People with lupus can go into spontaneous remission. If this happens to you, your doctor may cut back your medicine over time or stop your medicine.
Surgery isn't used to treat mild or moderate symptoms of lupus. But it may be considered for people who have permanent, life-threatening kidney damage. A kidney transplant or kidney dialysis may be done instead of continuing long-term treatment with high doses of medicines that have serious side effects.
While some people with lupus try alternative or complementary therapies (such as special diets, fish oils, or chiropractic treatment), these are not proven treatments for lupus.
Some therapies that focus on relaxation can help you cope with having a long-lasting (chronic) disease and may significantly improve your quality of life. These relaxation therapies include yoga, guided imagery, and massage.
Medicines and therapies now being studied are meant to change how the immune system works so that they can keep the disease from progressing. These newer treatments include stem cell transplantation and biologic treatment.
Immunoablation with or without
stem cell transplantation
is being studied as a treatment for severe lupus that has not been controlled with all other treatments. Immunoablation uses powerful drugs to wipe out the damaged immune system. After immunoablation, either the bone marrow is allowed to replace itself, or it is partially replaced through a stem cell transplant. The transplant replaces damaged or destroyed bone marrow cells with healthy cells, or stem cells. Stem cells are immature cells that are produced in the bone marrow. They can divide to produce more stem cells. Or they can mature into red blood cells, white blood cells, and platelets. More study of these treatments for lupus is needed.
Biologic treatment blocks specific steps in the lupus autoimmune process without suppressing the entire immune system. Researchers are currently experimenting with very specific substances, such as antibodies and nucleotides, that block certain steps of the autoimmune process. Rituximab is an antibody directed against certain immune cells that may have a role in lupus. It is approved for treating rheumatoid arthritis. Studies are looking at the use of rituximab for lupus. It is beginning to be used for lupus flares that have not responded to other immunosuppressive therapies. In some cases, rituximab has been associated with serious side effects such as breathing difficulty, heart problems, or severe infection. So the use of rituximab is closely watched.
Plasmapheresis, the removal of some parts of the blood, is rarely used as treatment for lupus except for certain severe cases.footnote 2
Intravenous gamma globulin (IgG) may be used to treat lupus that has not responded to other treatment. There is not good evidence that this works for lupus.
