IVIG is typically given as an infusion through your vein (intravenously), but some brands can also be given as an injection under the skin (subcutaneously).\u00a0<\/span>\r\n<span style=\"font-weight: 400;\">IVIG is commonly used to treat certain diseases of the nerves and muscles, including:<\/span>\r\n<ul>\r\n \t<li style=\"font-weight: 400;\" aria-level=\"1\"><a href=\"https:\/\/ameripharmaspecialty.com\/guillain-barre-syndrome\/gbs-guillain-barre-syndrome\/\"><span style=\"font-weight: 400;\">GBS (Guillain-Barr\u00e9 syndrome)<\/span><\/a><\/li>\r\n \t<li style=\"font-weight: 400;\" aria-level=\"1\"><a href=\"https:\/\/ameripharmaspecialty.com\/cidp\/what-is-cidp\/\"><span style=\"font-weight: 400;\">CIDP (chronic inflammatory demyelinating polyneuropathy)<\/span><\/a><\/li>\r\n \t<li style=\"font-weight: 400;\" aria-level=\"1\"><a href=\"https:\/\/ameripharmaspecialty.com\/myasthenia-gravis\/myasthenia-gravis\/\"><span style=\"font-weight: 400;\">Myasthenia gravis<\/span><\/a><\/li>\r\n \t<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Dermatomyositis<\/span><\/li>\r\n \t<li style=\"font-weight: 400;\" aria-level=\"1\"><span style=\"font-weight: 400;\">Multifocal motor neuropathy<\/span><\/li>\r\n \t<li style=\"font-weight: 400;\" aria-level=\"1\"><a href=\"https:\/\/ameripharmaspecialty.com\/other-health-conditions\/stiff-person-syndrome-causes-symptoms-and-treatment\/\"><span style=\"font-weight: 400;\">Stiff person syndrome<\/span><\/a><\/li>\r\n<\/ul>\r\n&nbsp;\r\n<h2><span class=\"ez-toc-section\" id=\"How_Long_Does_IVIG_Take_To_Work\"><\/span>How Long Does IVIG Take To Work?<span class=\"ez-toc-section-end\"><\/span><\/h2>\r\n<span style=\"font-weight: 400;\">It is difficult to know for sure. However, experience and research show that most people can start to feel better within a few days to weeks after the first treatment. However, not everyone responds to <a href=\"https:\/\/ameripharmaspecialty.com\/ivig\/a-guide-to-ivig-treatment-for-itp\/\">IVIG treatment<\/a>. People are categorized into two types: Responders and nonresponders.\u00a0<\/span>\r\n<span style=\"font-weight: 400;\">One study shows that 6 in 10 people with chronic inflammatory demyelinating polyneuropathy respond to IVIG treatment [<\/span><a href=\"https:\/\/www.ncbi.nlm.nih.gov\/pmc\/articles\/PMC9050528\/#\"><span style=\"font-weight: 400;\">1<\/span><\/a><span style=\"font-weight: 400;\">].<\/span>\r\n<span style=\"font-weight: 400;\">On the other hand, 8 in 10 people with <\/span><a href=\"https:\/\/ameripharmaspecialty.com\/other-health-conditions\/idiopathic-thrombocytopenic-purpura-itp\/\"><span style=\"font-weight: 400;\">immune thrombocytopenia<\/span><\/a><span style=\"font-weight: 400;\"> (ITP) respond to IVIG [<\/span><a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/34859421\/\"><span style=\"font-weight: 400;\">2<\/span><\/a><span style=\"font-weight: 400;\">].\u00a0<\/span>\r\n<span style=\"font-weight: 400;\">In those who respond, the time it takes for IVIG to work depends on several factors, such as:<\/span>\r\n<h3><span class=\"ez-toc-section\" id=\"Specific_IVIG_Brand\"><\/span>Specific IVIG Brand<span class=\"ez-toc-section-end\"><\/span><\/h3>\r\n<span style=\"font-weight: 400;\">IVIG products are unique and <\/span><a href=\"https:\/\/ameripharmaspecialty.com\/ivig\/are-ivig-products-interchangeable\/\"><span style=\"font-weight: 400;\">not interchangeable<\/span><\/a><span style=\"font-weight: 400;\">.
