My momhave epilepsy and doctor recommend tegretol tablets 200mg in morning 400 mg at night but i always forget morning one so can i take both together?

No.: Because of the rate at which tegretol is broken down, or metabolized, it needs to be dosed twice daily. If you only give it to her once a day you are increasing her risk of having a seizure. Having a seizure can result in serious injury or even death sometime. Do you and your mom a favor and set an alarm for her to take her pills. It is nice that you are trying to help your mom. Good luck!
