Lupus can be difficult to diagnose because its signs and symptoms often mimic those of other ailments. The most distinctive sign of lupus — a facial rash that resembles the wings of a butterfly unfolding across both cheeks — occurs in many but not all cases of lupus. Some anti-inflammatory agents and antibiotics are on the list, as well as so-called biologics used intravenously to treat rheumatic diseases. DILE has been observed with increased frequency in association with human leukocyte antigen (HLA)‒DR4.
In contrast, SLE affects individuals with slow and fast rates approximately equally. No specific criteria establish the diagnosis of DILE, and excluding underlying autoimmune disease is not a simple process. DILE is typically diagnosed by a process of elimination to rule out SLE (see Differentials).
A doctor may suggest supervised “drug holidays,” in which a person stops specific drugs for several months at a time. Symptoms are similar to those of another autoimmune condition called systemic lupus erythematosus (SLE) and include muscle and joint pain, fatigue, and rash. Hydralazine induced lupus is frequently manifested by arthralgia, myalgia, fever, rash (malar rash is common), hepatosplenomegaly, lymphadenopathy, and pleuritis. Rare cases of glomerulonephritis, neuropsychiatric manifestations and pericarditis have been reported. While arthralgia, myalgia, fever, and pleuritis are common in procainamide induced lupus, rash and lymphadenopathy are less common, and glomerulonephritis or CNS involvement is rare.
Rapid introduction of newly developed drugs in the absence of clear understanding of the pathophysiologic mechanisms behind drug-induced lupus erythematosus (DILE) can sometimes make DILE difficult to recognize in clinical practice. The purpose of this review is to summarize drugs most recently reported to be involved in DILE and discuss the current landscape of diverse mechanisms involved. SLE can be more difficult to diagnose in elderly people, since they often do not experience the typical features of the disease. Sometimes the symptoms can be very similar to those of drug-induced lupus.
- “My blood pressure drug hydralazine was to blame,” wrote one MyLupusTeam member, describing how they developed lupus.
- For pharmacists, an awareness of the potential adverse effects of these medications can help with the identification of this drug-induced syndrome in patients.
- The mild symptoms that are caused by the use of these medicines ceases after it is discontinued.
- For example, the first onset of typical subacute cutaneous LE in an older person, especially if involving the legs, should raise the suspicion of drug-induced LE.
Read on for a list of drugs that can cause lupus, how it’s diagnosed, and what you can expect if you have it. SLE is a chronic condition that can cause inflammation anywhere in the body, including internal organs such as the kidneys or lungs. If you have any concerns with your skin or its treatment, see a dermatologist for advice.
Unlike other lupus cases resulting from other medications, hydralazine-induced lupus usually doesn’t affect the heart, kidneys, or lungs. Procainamide is an antiarrhythmic — a drug that treats irregular heart rhythms. The incidence of lupus as a side effect has been reported to be as high as 30 percent, according to StatPearls, a clinic support tool.
Constitutional symptoms including myalgia, fever and weight loss are also common. Cutaneous involvement is frequent and may include photosensitivity, purpura, erythema nodosum, malar rash, and subacute cutaneous lupus erythematosus (SCLE) rash. Scarring alopecia, discoid lesions, and mucosal ulcers are less common in DIL than in SLE.
Ways To Save Money With Lupus: Insurance, Medication, Housing, and More
It may take several months of therapy with the medication before symptoms appear. For the high risk drugs such as procainamide and hydralazine, only 5 to 20 per cent of people treated for one to two years at currently used doses will develop drug-induced lupus. With most of the other drugs, the risk is less than 1 percent that those taking the medication will develop drug-induced lupus. It usually takes several months or even years of continuous therapy with the medication before symptoms appear. For people treated for one to two years at currently used doses of the high-risk drugs, approximately 5% of those taking hydralazine and 20% of those taking procainamide will develop drug-induced lupus.

Make sure to talk with your doctor before starting or stopping psychological dependence on alcohol: physiological addiction symptoms any medication. Some drugs need to be tapered off to avoid side effects, so don’t stop taking your medication abruptly without consulting a health care professional.
How quickly does drug-induced lupus develop?
Characterizing the mechanisms involved might help better understand the cause of idiopathic autoimmunity. A person may also experience autoimmune responses, including drug-induced lupus, after taking other medications. Minocycline induced lupus is more common in younger females, while procainamide or hydralazine induced lupus is more common in the elderly population. People with drug-induced lupus may complain of flu-like symptoms, especially muscle and joint pain. Symptoms may appear gradually and become worse after the person has taken the drug for several months. They are generally mild, but can become much worse if a patient continues to take the medication that is causing them.
Minocycline induced lupus is usually characterized by fever, arthralgia, arthritis, rash, and rarely pneumonitis and cutaneous vasculitis. Drug-induced lupus erythematosus is an autoimmune disorder that is triggered by a reaction to a medicine. DILE may be induced by medications or caused by other compounds in the environment. The most common drugs that cause drug-induced SLE are hydralazine (rate roughly 20%), procainamide (rate roughly 20%, 5-8% if taken for 1 y), quinine, isoniazid, and minocycline. Fever is found in similar incidence in both TNF-α inhibitor–induced DILE and DILE caused by other categories of medications.
Below are some of the most common questions and answers about drug-induced lupus. Since drug-induced lupus is likely to improve once you stop taking the drug, long-term treatment is usually not necessary. There are about 15,000 to 20,000 new cases of drug-induced lupus diagnosed each year in the United States, usually in people between 50 and 70 years old. Laboratory evaluation shall also include evaluation of complements (C3 and C4), renal function including urine to evaluate for proteinuria, liver function.
When to see a doctor
Drug-induced lupus carries a favorable prognosis with less morbidity and mortality as compared to SLE. In most cases, DIL resolves within a few weeks after discontinuation of the drug, with rare patients needing treatment for several months. Life-threatening disease is infrequent.[16] However, early recognition is crucial in preventing prolonged hospitalizations or multiple outpatient visits due to uncertainty about the diagnosis. Drug-induced lupus may develop a few weeks to several months after starting the drug, which may make the diagnosis difficult.
Varying mechanisms leading to the formation of self-recognizing antibodies may explain the differential characteristics of drug effects in persons with DILE and those with SLE. For example, whereas some drugs can cause DILE, others may cause a flare of preexisting SLE. Isoniazid (Nydrazid), an antibiotic april is alcohol awareness month national institute on alcohol abuse and alcoholism niaaa that’s used to treat tuberculosis, can pose a risk of liver damage and lupus. DIL happens in just 1 percent of people who take the drug, but one-fourth of people who take isoniazid will have ANAs. Like lupus occurring from procainamide use, hydralazine-induced lupus is most common among older people.
Nephritis may require treatment with prednisone and immunosuppressive medicines. Drug-induced lupus (DIL) is an autoimmune disorder that some people develop as a reaction to certain medications. DIL causes symptoms that are similar to those of systemic lupus erythematosus (SLE), the most common form of lupus. Skin rash is one of the most common clinical presentations of drug-induced lupus. The pathological examination of the biopsy from the skin rash in patients with DIL is similar to those with SLE. Your doctor may prescribe non-steroidal anti-inflammatory drugs (NSAIDs) to hasten recovery, if appropriate.
