Antacids/Cipro interaction?

Patient: I am a male, age 32 and was diagnosed with a urinary tract infection yesterday. I was prescribed Cipro and just took my 2nd pill. I have a reasonably regular heartburn and I took a TUMS about an hour and a half after I took my 2nd pill. THEN, I read by coincidence that I shouldn’t do that. Did I ruin the effect of the Cipro? If so, should I take another? Please explain the interaction between the 2 as well. Thank you.
