Can i take 5mgs klonopin with 1mg lunesta. having major panic?

No: Lunesta is not for anxiety, just for sleep, and the combo with klonopin can be dangerous. 5mg of klonopin is high-dose, so if panic remains on such a high dose, the klonopin is likely not the solution or perhaps withdrawal is occurring. Relaxation techniques would be helpful (e.g. deep breathing/mindfulness), and work with your Psychiatrist & Therapist on finding a better med for longer-term.
