Oil and gas LLC passive losses with no taxable income

I sold my interest in an oil and gas LLC and had passive losses that exceeded my passive gains, so I had unused passive losses (Sched E).   Also because my itemized deductions were so large from medical expenses I had no taxable income.  Since these passive losses are not needed to reduce my income (because of my very large itemized deduction) Can these passive losses be carried forward to a year where I don't have large itemized deductions or are these passive losses only able to be used in the year that I sold my interest in the LLC?
