 [ Symptoms ] i recently starting taking cymbalta for anxiety and every time i stand my head throbs like when your sick is this okay  i have only been taking cymbalta for two days now immediately i felt this problem though the day that i received the medicine i took it about mid day later that evening is when i began to feel the head throbbing as i stood i was on lexapro and i didnt have this side effect before that i tried celexa and had the same problem its a throbbing pounding that last for a few seconds the same way your head pounds when your sick and you stand up should i go back to the doctor or wait it out [ Disease ] also consider why you changed from lexapro lexapro is generally considered to be more effective in treating anxiety than celexa i know someone who had success with lexapro but the sexual side effects were too pronounced they switched to zoloft and had the same success and a decrease in sexual dysfunction
