The incident happened when the actor returned to Jaipur, where the show is being shot, after a visit to his hometown Nainital.
"I was down with high fever and almost fainted when a crew member from the production house fed me some sugar, chocolate syrup, and lime juice. Finally, I gained some energy and finished my close up shots. But later, again, I felt dizzy and was admitted to hospital where doctor decided to put me on a glucose drip," Sameer said in a statement.
He added: "Within a short while, I felt better and decided not to wait as long as the doctor had prescribed and reached the sets to continue shooting. I finished all my scenes for the day because I know what a unit goes through when actors go missing. Health comes first and I did tend to it, but I was not about to let my show suffer either."
