Paramedics were called to the penthouse suite around 10:15 a.m. last Friday. Lohan was not transported to a hospital.
Lohan tweeted early Saturday morning, blaming the long production hours for the incident: "Note to self.. After working 85hours in 4days, and being up all night shooting, be very aware that you might pass out from exhaustion & 7 paramedics MIGHT show up @ your door.... Hopefully they're cute. Otherwise it would be a real let down."
Lohan was hospitalized just last week after being involved in a car crash on Pacific Coast Highway.
The 25-year-old actress was with her assistant when she crashed her Porsche into the back of a dump truck.
After the accident, Lohan reportedly told police she was a just passenger in the car, but her assistant revealed the actress was actually driving.
TMZ says that the full police report includes the alleged lie, and could trigger a probation violation in her shoplifting case.
In March, a judge ended the actress' supervised probation on shoplifting and drunk-driving convictions.
But Lohan remains on informal probation until May 2014, and she could face up to 245 days in jail in her latest legal snafu.
Lohan has been to rehab multiple times for drug and alcohol abuse.
