 [ 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 ] it is possible that this is just a temporary side effect as your body adjusts to the new drug i would probably take a few more doses and go from there i recently started zoloft for anxiety along with my klonopin which i have been on for 2 years and i have had no side effects after 5 days none of the typical gastrointestinal nausea etc however cymbalta is an snri and zoloft is an ssri i am not sure but i do believe that snris can come with more side effects you may want to ask your doctor why an snri was chosen
