Rituximab, sold under the brand name Rituxan among others, is a monoclonal antibody medication used to treat certain autoimmune diseases and types of cancer. [18] It is used for non-Hodgkin lymphoma, chronic lymphocytic leukemia (in children and adults, but not recommended in elderly patients), rheumatoid arthritis, granulomatosis with polyangiitis, idiopathic thrombocytopenic purpura ...
[5] [6] When occurring as a result of a medication, it is also known as an infusion reaction. [ 1 ] The term cytokine storm is often used interchangeably with CRS but, despite the fact that they have similar clinical phenotype , their characteristics are different.
Medicare Part B (medical insurance) may cover Rituxan (rituximab) infusions. This is because medical professionals typically administer the medication in a medical setting on an outpatient basis.
Medications for a fast heart rate may include beta blockers, or antiarrhythmic agents such as procainamide, which attempt to restore a normal heart rhythm. [6] This latter group may have more significant side effects, especially if taken for a long period of time. [6] Pacemakers are often used for slow heart rates. [6]
Postural orthostatic tachycardia syndrome (POTS) is a condition characterized by an abnormally large increase in heart rate upon sitting up or standing. [1] POTS is a disorder of the autonomic nervous system that can lead to a variety of symptoms, [10] including lightheadedness, brain fog, blurred vision, weakness, fatigue, headaches, heart palpitations, exercise intolerance, nausea ...
Rapid and irregular heart rates may be perceived as the sensation of the heart beating too fast, irregularly, or skipping beats (palpitations) or exercise intolerance and occasionally may produce anginal chest pain (if the high heart rate causes the heart's demand for oxygen to increase beyond the supply of available oxygen).
Combinations of DMARDs are often used, because each drug in the combination can be used in a smaller dose than if it were given alone, thus reducing the risk of side effects. [citation needed] Many patients receive an NSAID and at least one DMARD, sometimes with low-dose oral glucocorticoids. If disease remission is observed, regular NSAIDs or ...
Structural heart disease, such as heart failure, myocardial infarction, and left ventricular hypertrophy, are also risk factors. Diuretic-induced hypokalemia and/or hypomagnesemia taken for heart failure can induce proarrthymia. The ischemia that results from myocardial infarctions also induce QT prolongation. [citation needed]
