I have had an itch and I asked my doctor about it. I have had it for about 2 months. I am 84 years old and I just recently, by doctors advice, reduced my Medication Effexor l75 mg to 75, then to 37.5 mg. I don't know if my itch is caused by this reduction, or from not enough humidity in my house. One of my doctors said if I took 1 Benadryl I could tell what my cause was. The only thing is that I can't remember if he said after 1 pill it would go away, then it was caused by a pill I m taking or my itch would continue and it was caused by the humidity.
