My wife aged 30 years suffered from severe vertigo few days back. She is on following medication: 1) Vertitac 16 mg, 2) Dom DT 10 mg, 3) Calistovit M, 4) Veloz 20 mg. She is taking these medicines since today morning. But, since evening she is suffering from diarrhea. She has gone for 5-6 times loose motions in last 2-3 hours. What would be the suggested medication for her on immediate basis. Is Norflox tz safe? Or, she should go for something else? Please suggest.
