    Can galantamine be stopped anytime? My dad doesn’t like the headache that comes with it. It makes him grumpy.


    Hi, Brad.. Unfortunately, it is not advisable to just stop galantamine unless told by his doctor to do so because if the medication will be stopped without a doctor’s advice, the benefits gained from the treatment will gradually fade away and symptoms of the disease may return.
    If the side-effect of this medication persists and is greatly affecting your dad, it would be best to consult with his doctor so he could make any necessary adjustment in the medications..


    Will there be any withdrawal symptoms when we do decide to stop galantamine?


    If you do decide to stop this medication, the most common side effects associated with the discontinuation would be dizziness, headache, nausea, vomiting, decreased appetite, diarrhea, weight loss, and abdominal pain. Do talk with the doctor before stopping it so that a proper course of action may be planned.
