Can I drink alcohol with levaquin (levofloxacin) and prednisone? Will it diminish the effects?

See below. Both Levaquin (levofloxacin) and Prednisone can irritate the stomach, and alcohol can intensify this effect. While alcohol shouldn't decrease their effectiveness, the 3 together might make you nauseated or have stomach irritation. I'd recommend not indulging until you've finished both of your prescriptions.
