Hi Jacque :lol:
These are some of the most common side-effects of plaquenil. Because a side effect is stated here, it does not mean that everyone using this medicine will experience all of these side effects:
Rash, Blurred vision, Changes in skin pigmentation, Dislike of light (photophobia), Balance problems involving the inner ear (vertigo),
Hair loss (alopecia), Disorders of the front layer of the eye (cornea),
Worsening of the skin condition psoriasis, Gastric disturbances including nausea, vomiting, gastric discomfort, constipation, diarrhoea, Worsening of porphyria, Disorder of the retina resulting in impairment or loss of vision.
Plaquenil is a Hydroxychloroquinine and is used in the treatment of systemic lupus erythematosus. In this disease, the body's immune system is over-active and slightly defective. The body develops antibodies which attack and cause damage to its own cells. Damage can occur anywhere in the body, such as in the joints or cartilage. As a result of the damage to the joints, reduced mobility and stiffness in the affected joints is experienced. Hydroxychloroquine is thought to act by interfering with the production and release of blood cells that are involved in the body's immune defence system. Hence the autoimmune response of the antibodies against its own body is reduced and as result, the amount of damage to the cells is minimized and prevented. As it has the potential to prevent progression of the disease, by limiting the damage caused, it is often referred to as a disease-modifying antirheumatic drug (DMARDS) and is commonly used very early in the treatment of Lupus. Hydroxychloroquine is also used in treating the skin conditions in Lupus that are caused or aggravated by sunlight.
This medication may cause a blurring of vision. If affected do not drive or operate machinery. Your doctor will probably have you take regular blood tests to check the levels of your blood components. Also, eye examinations are carried out before starting treatment with this medicine and repeated every six months in the course of the treatment. This medicine should be discontinued if you experience any visual problems.
I hope this has been helpful
Peace and Blessings
