Hydroxychloroquine (brand name Plaquenil) provides significant benefits primarily in the treatment of specific autoimmune diseases and for malaria. It works by modifying the immune system's activity and is classified as a disease-modifying anti-rheumatic drug (DMARD).
Cautions with other medicines
If you take antacids, leave a gap of at least 4 hours between taking them and hydroxychloroquine. Tell your doctor or pharmacist if you're taking any other medicines, including: azithromycin, erythromycin or clarithromycin, antibiotics. amiodarone or digoxin, medicines for heart problems.
About hydroxychloroquine Brand name: Quinoric
It works by blocking the effects of the chemicals released when your immune system attacks your body. It's used to treat inflammatory conditions, including rheumatoid arthritis, juvenile idiopathic arthritis (inflammation of joints in children) and lupus.
How long you take hydroxychloroquine for depends on why you're taking it. For some conditions, if hydroxychloroquine works for you then you may need to take it for several years, or even for the rest of your life, to control your symptoms.
Get medical help right away if you have signs like red, swollen, blistered, or peeling skin; red or irritated eyes; sores in your mouth, throat, nose, eyes, genitals, or any areas of skin; fever; chills; body aches; shortness of breath; or swollen glands.
Common side effects
Hydroxychloroquine (HCQ) has been widely used in rheumatic diseases. Some pSS patients are also receiving HCQ treatment. Studies have shown HCQ can significantly alleviate the symptoms of dry mouth, dry eyes, and joint pain in pSS patients and can also reduce circulating inflammatory factors.
Hydroxychloroquine starts to work gradually. For inflammatory conditions such as rheumatoid arthritis and lupus, it can take 6 to 12 weeks before you notice any benefits. It's important to keep taking hydroxychloroquine. You may not feel any different at first, but it is likely to be working.
Rheumatoid Arthritis Drugs With The Least Side Effects
Your physician will balance your quality of life with the severity of the disease when choosing the right med for you. The RA drug with the least side effects is hydroxychloroquine (Plaquenil).
The most common side effects are nausea and diarrhea, which often improve with time. Other side effects include rash, hair changes, and muscle weakness. Rarely, hydroxychloroquine can lead to anemia, typically in individuals with G6PD deficiency or porphyria.
Early signs of lupus often include extreme fatigue, joint pain/swelling, unexplained fever, and skin rashes, especially a butterfly-shaped rash on the face, but symptoms vary greatly and can develop slowly or suddenly, including hair loss, sun sensitivity, chest pain, and Raynaud's phenomenon (fingers/toes turning white/blue in cold). Because these symptoms mimic other conditions, seeing a doctor for persistent issues like headaches, mouth sores, or swelling is key for proper diagnosis.
With modern medicine, most people with lupus (SLE) can expect a near-normal lifespan, with 85-90% surviving at least 10 years post-diagnosis, and many living much longer due to earlier diagnosis and better treatments, though complications like heart disease, infection, and kidney issues remain major concerns. Factors like age at diagnosis, disease severity, race, and treatment adherence significantly influence outcomes, but overall, lupus management has vastly improved survival rates.
HYDROXYCHLOROQUINE (hye drox ee KLOR oh kwin) treats autoimmune conditions, such as rheumatoid arthritis and lupus. It works by slowing down an overactive immune system. It may also be used to prevent and treat malaria.
Hydroxychloroquine sulfate primarily affects vitamin B12, vitamin D, folate, calcium, and magnesium levels in the body. This medication, commonly used for autoimmune conditions like lupus and rheumatoid arthritis, can interfere with nutrient absorption and metabolism through several mechanisms.
It does not matter when you take your tablet, but because Hydroxychloroquine has a bitter taste, it is better to take them with food.
HCQ was found to trigger symptoms of psychosis, depression, suicidal ideation, mania/hypomania, anxiety, sleep disturbances, and cognitive impairments. The onset of these psychiatric side effects varied, appearing shortly after starting the medication to a more extended period.
Overexertion, poor sleep, stress or an infection like the flu can all set off RA symptoms.
Periods of severe symptoms or very advances stages of the condition can sometimes cause fatigue. Fatigue is different than normal feelings of tiredness. People describe it as being overwhelming and uncontrollable. They feel worn out and drained of energy, and sometimes even lose all interest in anything.
What is Hydroxychloroquine (Plaquenil®)? Hydroxychloroquine is used in the treatment of arthritis to help relieve inflammation, swelling, stiffness, and joint pain and also to help control the symptoms of lupus erythematosus (lupus; SLE). A common brand name for hydroxychloroquine is Plaquenil®.
If you take a 200-milligram dose of hydroxychloroquine, it takes 22 days for your body to break down half (100 milligrams). For the remaining 100 milligrams, it takes another 22 days to break down half (50 milligrams), and so forth. Therefore, it can take months to clear your system of hydroxychloroquine.
Inhibition of systemic inflammation and autophagy by hydroxychloroquine has been linked to antineoplastic effects. Currently, multiple randomized controlled trials have been conducted using hydroxychloroquine as an anticancer drug or as an add-on to existing chemotherapeutic regimens [1].
Specific Testing: During the Plaquenil eye exam, several specialized tests may be performed, including: Visual Acuity Test: To assess overall visual function. Amsler Grid Test: To detect any distortions or changes in central vision. Color Vision Test: To check for color vision abnormalities.
A twenty-eight-year-old woman with discoid lupus erythematosus was treated only with hydroxychloroquine. After seven months of this therapy, a diffuse bluish-gray pigmentation was apparent on the vestibular surface of the gums of both dental arches. No pigmented lesions were noticed on either the skin or the nails.
