Gasol finished with 25 points and 14 rebounds, and Andrew Bynum had 16 points and 17 rebounds to help the Lakers snap a two-game skid.
Allen scored 22 points and Kevin Garnett had 12 points and 12 rebounds for Boston, which had won five in a row and nine of its previous 10. But Garnett was 6-for-23 from the field and Paul Pierce was 7-for-18, including a clean-look jumper at the end of OT.
It rimmed out and Allen tried to push the rebound in, but Gasol got his fingertips on it and it floated away as the buzzer sounded.
The Lakers had lost six of their last seven road games.
But a trip to Boston to play the rival Celtics was just what they needed.
Both teams shot under 40 percent, and they each missed twice to start the overtime before Kobe Bryant sank a jumper that gave the Lakers an 84-82 lead with 3:30 to play. Allen missed, then Steve Blake made a jumper to give the Lakers a four-point lead.
Pierce made a jumper and, after Gasol missed, Pierce hit a 3-pointer over Metta World Peace to make it 87-86 Boston. Bryant missed, but Bynum tipped it in with 1:30 remaining to give L.A. the lead, and it held up.
