I went to.my psychologist with problems of anxiety, depression and insomnia. My problem is my anxiety medicine doesn't work. I went to look up if it was safe to take a another dose but the problem is I cannot find it on any pill identification website! It has H on the front and 500 on the back its white and round. Someone please help! I was told it is hydroxyzine HCl 10 mg but I cannot find it anywhere!
