Hi Dr, my younger brother suffering from abdominal Koch's. He is advised to take forecox for first 2 month then Dr. change the medicine including ethambutol (450 mg) rifampicin (800 mg) and solonex (100 mg 100 mg) After 45 days of taking these three medicine. One dose of solonex is missed then what should do? We are very confused and worried about these. Please Dr. guide. Our physician is not available at this time to guide us.
