My mother had a blod clot in her left side of the brain 5 years ago. She didn t undergone any surgery. She became well only by using the tablets prescribed the doctors. However, doctor suggested her to use the tablets for her lifetime. However, she stopped using those tablets 10 months ago, except the BP tablet. And she is keeping well now. Is that true that she should continue to use all those tablets for her lifetime. If we don t use those tabs for lifetime, will it cause any harm.
