  • In addition to opportunistic infection, you can autoimmune disorders (a condition in which the immune system attacks healthy body tissue) may also occur after you start taking medicines to treat your HIV – infection. Autoimmune disorders can occur several months after starting treatment. If you notice any symptoms of infection or other symptoms such as muscle weakness, a weakness that starts in the hands or feet and moves to the torso, palpitations, tremors, or hyperactivity, inform your doctor immediately for the necessary treatment.
