I was taking generic for claritin and stopped it because It took care of my symptoms at the time. I think about 2 weeks was the duration about. I have noticed rapid receeding gumline and seems like the taste of peroxide in my mouth all the time and a tingly sensation also. I tried some green tea to hopefully flush out the taste and symtoms quicker but imediately got a super dry tongue and gums. I have very nice teeth that the dentist always says I must have had braces, they are very aligned. I didn't just teeth pulled and applied pressure to the teeth that were really sticking forward at night or when I remembered. Now It seems my gums are deteriorating rapidly because my salvia is more seemingly acidic. I am leaving on a mission's trip in a few days and feel like I hope this stops breaking down or my teeth may just fall out in my hands. Do I need a medication to stop the chemical reaction? Like steroids. That stuff makes me so gittery and busy. Just wondering what I am to do. I remember now the reason I quit taking the med. was I had halusinating dreams. I pray I remember never to take this drug again. I may loose my gums and teeth and really they are in good health up til this.
