Idiosyncratic hypersensitivity reactions have occurred.For prolonged treatment of lupus or rheumatoid arthritis, adverse effects include the acute symptoms, plus altered eye pigmentation, acne, anemia, bleaching of hair, blisters in mouth and eyes, blood disorders, cardiomyopathy, convulsions, vision difficulties, diminished reflexes, emotional changes, excessive coloring of the skin, hearing loss, hives, itching, liver problems or liver failure, loss of hair, muscle paralysis, weakness or atrophy, nightmares, psoriasis, reading difficulties, tinnitus, skin inflammation and scaling, skin rash, vertigo, weight loss, and occasionally urinary incontinence. Hydroxychloroquine can worsen existing cases of both psoriasis and porphyria.Children may be especially vulnerable to developing adverse effects from hydroxychloroquine overdoses. Eyes
One of the most serious side effects is retinopathy (generally with chronic use). People taking 400 mg of hydroxychloroquine or less per day generally have a negligible risk of macular toxicity, whereas the risk begins to increase when a person takes the medication over five years or has a cumulative dose of more than 1000 grams. The daily safe maximum dose for eye toxicity can be estimated from a persons height and weight. Macular toxicity is related to the total cumulative dose rather than the daily dose. Regular eye screening, even in the absence of visual symptoms, is recommended to begin when either of these risk factors occurs.Toxicity from hydroxychloroquine may be seen in two distinct areas of the eye: the cornea and the macula. The cornea may become affected (relatively commonly) by an innocuous cornea verticillata or vortex keratopathy and is characterized by whorl-like corneal epithelial deposits.
Medical uses
Daratumumab/hyaluronidase is indicated for the treatment of adults with multiple myeloma:
in combination with bortezomib, melphalan and prednisone (D-VMP) in newly diagnosed adults who are ineligible for autologous stem cell transplant
in combination with lenalidomide and dexamethasone (D-Rd) in newly diagnosed adults who are ineligible for autologous stem cell transplant and in people with relapsed or refractory multiple myeloma who have received at least one prior therapy
in combination with bortezomib and dexamethasone (D-Vd) in adults who have received at least one prior therapy
as monotherapy, in adults who have received at least three prior lines of therapy including a proteasome inhibitor (PI) and an immunomodulatory agent or who are double-refractory to a PI and an immunomodulatory agent.In January 2021, the U.S. Food and Drug Administration (FDA) granted accelerated approval to daratumumab/hyaluronidase in combination with bortezomib, cyclophosphamide, and dexamethasone for newly diagnosed amyloid light-chain amyloidosis.In November 2021, the FDA granted  approval to daratumumab/hyaluronidase in combination with carfilzomib plus dexamethasone to treat relapsed or refractory multiple myeloma in adults who have received one to three prior lines of therapy. History
It was approved for use in the United States in May 2020.Efficacy of daratumumab and hyaluronidase-fihji (monotherapy) was evaluated in the COLUMBA trial (NCT03277105), an open-label non-inferiority trial randomizing 263 participants to daratumumab and hyaluronidase-fihj and 259 to intravenous daratumumab (daratumumab IV). The trials co-primary endpoints were overall response rate (ORR) and pharmacokinetic (PK) endpoint of the maximum Ctrough on cycle 3, day 1 pre-dose.
