Hi. My younger brother has severe migraine problem. We took him to peerless hospital neuroscience department. He has weak nervous system & can't take any pressure. Doctor gave him Nexito 5 mg tablet 2nd time, 1st time he prescribed Nexito 1 mg. But after taking Nexito 5 mg ,he feels always restless, can't sleep properly, if he wants to remember something ,he feels pain severely. Now what should we do now?
