Also known by its trade name “Benlysta”, Belimumab is used in combination with other medicines to treat lupus (a disease that causes inflammation of the skin). It is worth noting that this medication received FDA approval for the treatment of systematic lupus (SLE) on March 9, 2011. According to webmd.com, Belimumab works by decreasing the effect of a certain protein that is increased in people with active lupus, which helps decrease some of the symptoms of systematic lupus. Before using this treatment, you need to tell your doctor that you’re going to take it, because “in some drug studies, more deaths happened in people taking Belimuma compared to those not taking it”(quoted from drugs.com). Therefore, you need to make sure that the other drugs that you’re taking or that you may take in the future, won’t interact with Belimuma. You should also tell your doctor beforehand if you’re allergic to a certain drug, food or substance. According to drugs.com, chest pain, signs of infection and allergic reactions are some of the side effects that may occur as a result of using Belimuma. Besides, you can also experience excruciating headaches, shortness of breath, nausea and diarrhea. It’s preferable that you get medical help if you have any of these side effects. Bear in mind that this treatment is given as a shot into the fatty part of the skin on the top of the thigh or the belly area.
