Hi i have just recieved pepcid AC 60 pack in the mail from the US.
I have noticed that they expire in this month, 01/07.
Is it bad to use these pills when they become expired? The container still has its seal intact.

I also suffer from the asian flush, i am half chinese on my dads side and I live in New Zealand.  When i drink alcohol my face turn red and eyes go bloodshot, I also get a headache and my face heats up.
I tried to get pepcid/pepzan from the pharmacy but they did not sell it and said it was discontinued.  I picked up the Zantac and it helped, my eyes did not go red but my face was still a pink colour which looked liked i was slightly sunburned.  I only took one tablet, I will take more next time when i go out but what happens if i excede the amount which is stated as two?  That morning i took a hayfever relief pill called telfast because i had a slight case of hayfever, do you know if that would of had any affect on my results?  How much Zantac tablets should i take?? I brought the 28 pack containing 150mg of Ranitidine, does it make a difference if you take more?  Should i eat or not?
Sorry for all the questions, most can proberly answered if i read other peoples input.
