Doctor, My Mother is having tinnitus and she is taking Vertin 16. Also she has rheumatoid arthritis for which she took Sazo 1000, Supracal D, Folitrax and Prednisone for almost 3 years which was described by her physicians. The problem started for last 1 month, she is frequently getting drowsiness and tired. We consulted a neuro physician who took serum test and concluded that she has loss of Vitamin D3. He ha suggested for ReNerve injection for 1 week and to continue Vertin if she has tinnitus. She is getting very much drowsy after taking Vertin and gets tired. How to get her back to normal? Kindly help Her age is 60.
