Immediately after taking them, I felt good and a lot of the troubles I have been having with my mouth(white spots on
tongue,
sore throat) disappeared. Then, on the fourth day, it all returned with a vengeance. Sore throat, dry cough, white coated tongue, and since then has only gotten worse. I stopped the Zantac after about 12 days and on that day my neck started to ache like crazy. The day after I was in pain and had a bad sore throat, still dry coughing. Is this a side effect of the Zantac?
