If you mean Toaru Majutsu no Index, then i would read the LN or watch at least the Anime, because the manga skips some arcs and is behind the LN. Even the Anime outdated it. While the LN has already (if we include NT and the side stories) 35 - 40 volumes, the manga is at volume 9-10 and the anime is 13, so I would recommend to read the LN.

If you mean Toaru Kagaku no Railgun, then is there no problem to read it, because it follows the plot from Kamachi, but i wouldn't watch the anime, because it has a lot of filler that mess the timeline.
