Is it normal to feel panicky and have heart palpitations on this medicine? I've been on it for 4 days and I feel like I'm going crazy and I'm ready to be admitted. My body temperature feels like it's skyrocketing even if I don't have a fever. I hardly eat. I have panic disorder and mild depression which is why I got on it. I'm taking 25 mg and I'm supposed to increase to 50 in 2 weeks. I hyperventilate and sometimes I feel like I can't breathe. It stresses me out and upsets me because I thought it was supposed to help but it's getting worse. Is this normal? I'm also 18 years old
