Hi Dr, My father is 63 yrs of age. He was diagnosed with Myasthenia gravis 3 months back and is on medication. A month back he was also diagnosed with pulmonary tuberculosis and the dr prescribed combunex and rcin. 15 days back he had two back to back convulsions and the MRI showed tb strains on the left side of the brain. He was then put on 16 mg predmet along with rcin 450 and combunex. Predmet is being tapered and now is at 12 mg/day. His liver function test was done two days back and is normal. The dr would now start Pzide.But he has been experiencing mild headache on his left side since past 10 days. He is also been administered oxcazo 300 mg twice a day and Oresta 10 mg for 15 days. Oresta will be discontinued in couple of days. He also sometimes forget a few words while speaking but that is not seen often. Kindly advise if headache is a normal symptom and how many days will it take to completely vanish? Also suggest on the forgetfulness.
