I have to agree with the other poster. 3 days isn't long enough to determine if the medication is going to work, and the fact that her period is starting could have an effect too. Some meds take weeks to take effect so she should take them for awhile to see if they're going to work, and to see if she has any side effects and if so, to see if she can tolerate them or if they go away.

Like the poster said, DON'T let her stop them abruptly because that can be very DANGEROUS. With some meds, it you stop abruptly, it can cause seizures and other nasty problems so speak with your doctor before stopping them!

I wish you the very best! Please take care, and God bless. Hugs, Lee
