After India took the decisive match by 49 runs to claim their first victorious tour of the West Indies in 35 years, Lara expressed his frustration with regional cricket authorities.
Lara said he would make a decision on his future tenure as captain after a new panel of selectors was appointed.
"It's unfortunate. I think the selectors are coming up for election very soon and depending on the outcome of that, I definitely have to revisit my decision to captain the West Indies team," Lara told reporters on Monday.
"It's painful what has gone on in the last couple of months, not just the Test matches, but the one-day matches too," he added.
"I have West Indies cricket at heart, but it's a situation where my reputation as a captain is being dragged down."
Lara also revealed that he received a letter from the regional governing body on the eve of the final Test, notifying him that he was a member of the selection panel, effective from May 28.
It was against this background that he complained during the series that he was not a selector and he was not getting the teams he wanted to take on to the field.
"It's unfortunate that, first of all, I have been a selector, as I understood, since the series started, since May 28 after the one-day matches," he said.
"It's hurtful when you know that you are in the team, you know the chemistry of the team, but you can't do anything about it."
"I said in the press conference after (the second Test in) St Lucia that in hindsight, a spinner should have played, yet two days later he was dropped from the entire 14. How do you work these things out?"
Lara was appointed captain for a third time in April after former captain Shivnarine Chanderpaul resigned from the post.
He had previously led the West Indies between 1998 and 2000 and again between 2003 and 2005.
