Citalopram Serotonin Syndrome Causes and Reviews


Antidepressants are medicines that treat depression. Your doctor can prescribe them for you. They work to balance some of the natural chemicals in our brains. It may take several weeks for them to help. There are several types of antidepressants. You and your doctor may have to try a few before finding what works best for you.

Antidepressants may cause mild side effects that usually do not last long. These may include headache, nausea, sleep problems, restlessness, and sexual problems. Tell your doctor if you have any side effects. You should also let your doctor know if you take any other medicines, vitamins, or herbal supplements.

It is important to keep taking your medicines, even if you feel better. Do not stop taking your medicines without talking to your doctor. You often need to stop antidepressants gradually.

I have been prescribed Citalopram and for the first two months had started to feel better. However I noticed on my third prescription my regular pharmacist had changed the brand to aurobindo I didn't think anything of it at the time . However after two days of taking , I have started to experience a lighthead / dizziness. I continued to take the tablets hoping that the this would go , unfortunately it has become worse , to the point where I haven't wanted to partake in my usual activities , walking , swimming and daily tasks. I visited my GP yesterday who dismissed my experience . He did give me another prescription which I have taken to my regular pharmacy, who dispensed the original brand which I had previously taken without any side effects . I have decided to start coming of this type of medication due to my recent bad experience and shall begin reducing my dose over the next few weeks .
