If you have lupus or a condition that predisposes you to lupus, such as undifferentiated connective tissue disease (UCTD), there are certain foods and medications that you should avoid. The substances listed below have shown to induce lupus signs and flares and should be avoided by people with lupus or autoimmune diseases suggesting “pre-lupus.”
(1) Sunlight
People with lupus should avoid the sun, since sunlight can cause rashes and flares. Some people are more sensitive to sunlight than others, but all people with lupus are advised to be cautious when they are outside. Of course, it would be impractical to completely avoid going outdoors, but try to be prepared. Carry a sunscreen with an SPF of at least 70 and be sure that your sunscreen contains Helioplex, an ingredient that blocks UV-A and UV-B rays, both of which are harmful to people with lupus. Apply sunscreen to all areas of the body, even those covered by your clothes, since most normal clothing items only protect your skin to the level of SPF 5. In addition, carry a hat with you when you know you will be outside. Certain sportswear manufacturers now make hats with SPF built into the material, which may be helpful for people with greater photosensitivity.
(2) Bactrim and Septra (sulfamethoxazole and trimethoprim)
Bactrim and Septra are antibiotics that contain sulfamethoxazole and trimethoprim. They are grouped as “sulfa” antibiotics because they contain a substance called sulfonamide. Bactrim and Septra are often prescribed for bacterial infections, especially urinary tract infections. They are also sometimes given prophylactically (i.e., to prevent infection), especially in people taking immunosuppressive medications. However, it is very important that you avoid Bactrim and Septra, because these antibiotics are known to cause an increase in sun sensitivity and lower blood counts in people with lupus, resulting in lupus flares. Several medications can be used instead of Bactim or Septra for the prevention and treatment of infection; perhaps the most frequently used substitute is Dapsone (diaminodiphenyl sulfone) to prevent Pneumocystis pneumonia.
(3) Garlic
Scientists believe that three substancs in garlic—allicin, ajoene, and thiosulfinates—rev-up your immune system by enhancing the activity of white blood cells, particularly macrophages and lymphocytes. Scientists also believe that the sulfur components of garlic help to prevent and suppress cancer in the body. For this reason, garlic is often used as a supplement to combat colds and infections. Unfortunately, the enhancement of immune response is counterproductive in people with autoimmune disease such as lupus, because their immune system is already overactive. As a result, people with lupus and lupus-like signs should avoid cooking with garlic and adding it to food. Of course, a tiny amount of the herb will not harm you, but try to consciously avoid purchasing and preparing foods with garlic.
(4) Alfalfa Sprouts
Alfalfa sprouts contain an amino acid called L-canavanine that can increase inflammation in people with lupus by stimulating the immune system. As a result, people with lupus and similar autoimmune conditions should avoid alfalfa sprouts completely.
(5) Melatonin and Rozerem (ramelteon)
Melatonin is a hormone secreted by the pineal gland in your brain that regulates other hormones in the body that control how your body reacts to daily patterns of light and dark. Melatonin release is suppressed during the light hours of the day and stimulated by dark, helping you stick to patterns of nighttime sleep and daytime wakefulness. As a result, melatonin is often used as a sleep aid over other medications. Melatonin and melatonin-containing supplements should be avoided in people with lupus and other autoimmune disorders because they may stimulate the immune system. In addition, people with these conditions should also avoid the prescription sleep aid Rozerem (ramelteon), because it mimics melatonin in the body. It is important that you understand the necessity of avoiding both melatonin and Rozerem, since sleep aids are often used to help people with fibromylagia and other conditions to attain normal sleep patterns. In general, be sure that you speak with your physician before taking any new medications or supplements.
(6) Echinacea
Echinacea is often used as a dietary supplement to boost the immune system against colds and other illnesses. However, because Echinacea boosts your immune system, it may cause flares in people with autoimmune diseases such as lupus. In fact, Echinacea supplements sold in Europe bear warning labels that advise against use by people with autoimmune diseases. As a result, people with lupus and other autoimmune diseases should avoid these supplements. In general, it is important that you speak with your physician before taking any new medications or supplements.
