The treatment for each immunodeficiency disorder will depend on the specific conditions. For example, AIDS causes several different infections. Your doctor will prescribe medications for each infection. And you may be given an antiretroviral to treat and HIV infection if appropriate. Treatment for immunodeficiency disorders commonly includes antibiotics and immunoglobulin therapy. Other antiviral drugs, amantadine and acyclovir, or a drug called interferon are used for treatment of the viral infections caused by immunodeficiency disorders. Primary immunodeficiency disorders can be controlled and treated, but they can’t be prevented. Secondary disorders can be prevented in a number of ways. Sleep is very important for a healthy immune system. According to the Mayo Clinic, adults need about eight hours of sleep per night. It’s also important that you stay away from people who are sick if your immune system isn’t working properly. Primary immunodeficiency disorders — also called primary immune disorders or primary immunodeficiency — weaken the immune system, allowing infections and other health problems to occur more easily. Many people with primary immunodeficiency are born missing some of the body's immune defences or with the immune system not working properly, which leaves them more susceptible to germs that can cause infections.
