How do doctors help prevent infections during treatment?

Some of the approaches to manage infection risk are: 

Close monitoring: Regularly checking your immunoglobulin levels as well as monitoring the presence of common viral and bacterial infections and viral reactivations. Early detection allows for prompt treatment, minimizing potential complications.

Prophylactic medication: In some cases, doctors may prescribe preventive antibiotics or anti-virals such as Acyclovir, Valacyclovir, or Bactrim, to help prevent infections before they occur.

Immunoglobulin replacement therapy: If immunoglobulin (IgG) levels become very low, this therapy involves receiving infusions of healthy antibodies to strengthen your immune system; this is also referred to as IVIG therapy.

Maintaining good hygiene: Simple practices like frequent handwashing and avoiding contact with sick people remain crucial in preventing infections.
