Effect of Latent TB medicine on marathon training

As some of you know I have been training for a marathon (November 15th). I was concerned about the effect of the TB medication on my training. The first week after the medicine I was quite lethargic and did not have a good weekend run. I was wondering whether it was related to the antibiotics. Once again, there is not much research on this. I found one paper which said that there is not much of an impact (but strangely said that Vo2 max levels did go down). My ID doctor in Stanford assured me that there should be no impact on my training.

I am happy to report that the second week (after antibiotics) went quite well. I finished my 20 miler on Sunday (three days ago) and I had the fastest time of this season. So I am really pumped. Third week is going well as well. So I suspect the reasons for the fatigue in the first week were either coincidence or related to stress because of all the things circling the donor approval process.
