IPT (Isoniazid Preventive Therapy)

Isoniazid Preventive Therapy (IPT) is a medical treatment used to prevent tuberculosis (TB) in people at high risk, such as those with weakened immune systems. It involves taking the medication isoniazid over several months to eliminate dormant TB bacteria that might be present in the body. Since these bacteria can become active later and cause illness, IPT helps reduce this risk, especially in people living with HIV or in areas with high TB prevalence. It is a proven strategy to protect vulnerable individuals from developing active TB disease.
