Should i take medication for inactive/latent tuberculosis infection?

Do you have it?: That's a hard question to answer based on the information you've provided. If you have a positive skin test or blood test for latent tb, the indications for treatment depend on your age, your other medical conditions, your risk of having true latent infection, and the strength of the reaction (e.g. Size of the positive skin test). This is something you should discuss with your doctor.
