I am a 69 year old male who experienced upper gastric pain and was prescribed Mucosta t.i.d. times 7 days. After the very first dose of 1 tablet I began serious side effects: hypertension, constipation, inability to concentrate and panic attacks related to my inability to stop the effect of the drug. Depression and inability to experience happiness, or pleasure. I suspect my hypersensitivity may be related to the fact that I have genetically evolved essential tremor for which I have taken Corgard/Nadalol 40 mg for the past 20 years. WHAT IS THE HALF LIFE of Mucosta? I was given a 40 mg dose of Pantoloc which I also stopped taking after the first pill. I switched back to Omeprazole 20 mg which I took before with no problems and it seems to have ended the gastric pain.
