If you have allergic asthma, your body produces more IgE when you breathe in air containing an allergen, leading to an asthma attack. This can trigger a series of chemical reactions in a process called the allergic inflammatory cascade, which occurs in allergic asthma.<\/span><\/p>\n<p class=\"ds-markdown-paragraph\" style=\"text-align: justify;\"><span style=\"font-size: 14pt;\"><strong>What is the difference between Xolair and other asthma medications?<\/strong><\/span><br \/>\n<span style=\"font-size: 14pt;\">This medication comes as an injection containing an active ingredient from the class of monoclonal antibodies. It is used as an add-on treatment for severe allergic asthma caused by pollen, dander, and dust. An allergic reaction occurs when the immune system activates and attacks these triggers, releasing IgE antibodies. This drug is specifically engineered to recognize the antibodies naturally produced by the body due to allergies. It binds to them, preventing them from attaching to allergens and also preventing them from binding to basophil cells and releasing the chemicals that cause allergy symptoms. In other words, this drug prevents the body&#8217;s allergic reaction that leads to an asthma attack.<\/span><\/p>\n<p class=\"ds-markdown-paragraph\" style=\"text-align: justify;\"><span style=\"font-size: 14pt;\"><strong>What are the possible side effects of Xolair?<\/strong><\/span><br \/>\n<span style=\"font-size: 14pt;\">The most common side effects reported by patients are:<\/span><\/p>\n<ul style=\"text-align: justify;\">\n<li>\n<p class=\"ds-markdown-paragraph\"><span style=\"font-size: 14pt;\">Reaction at the injection site (bruising, redness, warmth).<\/span><\/p>\n<\/li>\n<li>\n<p class=\"ds-markdown-paragraph\"><span style=\"font-size: 14pt;\">Viral infections.<\/span><\/p>\n<\/li>\n<li>\n<p class=\"ds-markdown-paragraph\"><span style=\"font-size: 14pt;\">Upper respiratory tract infections.<\/span><\/p>\n<\/li>\n<li>\n<p class=\"ds-markdown-paragraph\"><span style=\"font-size: 14pt;\">Sinusitis.<\/span><\/p>\n<\/li>\n<li>\n<p class=\"ds-markdown-paragraph\"><span style=\"font-size: 14pt;\">Headache.<\/span><\/p>\n<\/li>\n<li>\n<p class=\"ds-markdown-paragraph\"><span style=\"font-size: 14pt;\">Sore throat.<\/span><br \/>\n<span style=\"font-size: 14pt;\">Less common side effects include bone pain, leg pain, dizziness, joint pain, muscle pain, joint swelling, and hair loss.<\/span><\/p>\n<\/li>\n<\/ul>\n<p class=\"ds-markdown-paragraph\" style=\"text-align: justify;\"><span style=\"font-size: 14pt;\"><strong>Who should not take Xolair?<\/strong><\/span><br \/>\n<span style=\"font-size: 14pt;\">You should not take Xolair if you are allergic to Omalizumab or any of the ingredients in this medication.<\/span><\/p>\n<p class=\"ds-markdown-paragraph\" style=\"text-align: justify;\"><span style=\"font-size: 14pt;\"><strong>How is Xolair taken?<\/strong><\/span><br \/>\n<span style=\"font-size: 14pt;\">The medication is given as a subcutaneous injection (under the skin).<\/span><\/p>\n<p class=\"ds-markdown-paragraph\" style=\"text-align: justify;\"><span style=\"font-size: 14pt;\"><strong>How often is Xolair given?<\/strong><\/span><br \/>\n<span style=\"font-size: 14pt;\">Xolair is given once every two weeks or every four weeks, depending on the dose determined for each person based on body weight and IgE level.<\/span><\/p>\n<p class=\"ds-markdown-paragraph\" style=\"text-align: justify;\"><span style=\"font-size: 14pt;\"><strong>How quickly does Xolair work?<\/strong><\/span><br \/>\n<span style=\"font-size: 14pt;\">It is very important to understand that Xolair takes time to start working.
