i took a ranitidine this morning and during and hour after lunch i feel my hearts racing i am just wondering if i can take both the ranitidine and omeprazole tonight. i did not have any panic attacks nothing that would make my heart race and i am not dizzy.  oh i had a blood test done which show that i had h-pylori and i had 10 days treatment of antibiotics along with the omeprazole. please tell me if it is safe to take the omeprazole and the ranitidine tonight just once. and a ranitidine tomorrow morning. 

thanks
